Ian McCollum: “Why The M7 And 6.8x51mm Are Bad Ideas”

Sunday, December 7th, 2025

I’m not enough of an expert to know whether the new M7 U.S. battle rifle chambered in 6.8x51mm is a good idea or not. But I’m pretty sure Ian McCollum is such an expert, and he says it’s a bad idea:

  • “I have thought from the very beginning that this program was a bad idea.” As evidence by this snippet from 2019.
  • “I really didn’t expect that that the US Army would adopt anything from the NGSW program. We do have a long history of doing weapons development trials, looking at all the options, and adopting nothing new. And that’s what I thought would happen here. Obviously, it didn’t.”
  • “I had a chance to do some shooting with a civilian 68 by 51 or 277 Fury Spear rifle, the civilian version of the M7 several years ago. It was a good rifle. Um, like as a technical thing, it worked well. It handled well, but that doesn’t mean that it’s a good idea for the military to adopt it.”
  • “This video isn’t about the rifle itself. It’s about the doctrine and the concept behind its adoption, which is the part that I think is a really bad idea.”
  • “There were two main justifications that are typically given for the decision to get rid of the intermediate, light recoiling, highc apacity cartridge, the 5.56 [NATO], and replace it with a much higher pressure, much heavier recoiling, much physically larger and physically heavier cartridge, the 68 x 51[mm].”
  • “The first one is when we were in Afghanistan, US troops were often taken under fire by enemy forces from ranges at which they could not effectively respond with their little wimpy 5.56 M4s. And that’s very true. Something like 50% of combat engagements in Afghanistan took place in excess of the practical engagement range of the M4.” Taliban would routinely ambush U.S. troops from higher in the hills “800 or 1,000 meters away.”
  • “And so the justification is often given that if we had some big honking rifle with a magnified optic on it that could reach out to 800 yards, well then, by gosh, we could have taken that dude out.”
  • “And my counter to that is that the world has changed since we were fighting in Afghanistan.”
  • “But if that were happening today, you know what the answer would be? It’s not rearm everybody in the Humvee. It’s you have a box of a couple of little one-way attack drones sitting in the Humvee.”
  • “We’ve all seen the drone footage from Ukraine. Like that’s exactly what would happen if we were in Afghanistan dealing with that situation today. There’s no need for a new small arm to do it.”
  • “And it’s so totally counterproductive to make all the sacrifices of going back to a full power battle rifle in order to be able to do what you can do more effectively with, I don’t know, a couple thousand military procurement one-way attack drone.”
  • “The second justification was armor penetrating capability. Our potential near-peer allies are developing really good, next generation body armor and we need our infantry weapons to be able to defeat that body armor. And I think this is also a mistake, or I think the adoption of the M7 is not the ideal solution to that problem either.”
  • So they needed armor penetration but want to keep the rifle short for usability, and to put a suppressor on it. “This is how we end up with a 13-in barrel that has to achieve 30 something feet per second, which means you have to jack the pressure, the chamber pressure of the cartridge way up in order to get a high, you know, 140 or 130 grain bullet at 3,000 plus FPS.”
  • “Now we have an 80,000 PSI cartridge. And interestingly, looking at Cappy Army’s video, in order to try and mitigate the weight issue, Sigs M71 actually cuts the barrel down even shorter to 11 in. And the SIGR rep that they had in that video was talking about potentially upping chamber pressures to 125,000 PSI…Maybe that’s that’s a typo. Maybe that’s a misspeaking thing.”
  • 80,000 PSI is already really high. Most cartridge pressures top out around 65,000 PSI. At 80,000 PSI, the M7/.277 Fury is already the highest pressure cartridge in the world. 125,000 PSI is simply insanely high.
  • “To me, that’s just mind-bogglingly insane. Like, at that sort of pressures your barrel life is going to be abysmal. Your parts life and everything is going to be abysmal. Like that’s that’s not a really good compromise to achieve higher velocity.”
  • “There are capabilities out there for armor penetration that are much more focused on bullet construction and don’t need to have necessarily the sort of super hyper velocity that you get out of an 80,000 PSI cartridge.”
  • “I recently had the chance to visit CBJ in Sweden. The 65 CBJ cartridge is a pistol caliber cartridge that uses some velocity, but also a lot of material science and projectile design to create a remarkably effective, to many people a shockingly effective, armor penetrating cartridge without having to do a whole lot. And they do it in the chamber pressures of 9 by 19 parabellum.”
  • “If you took the guys from CBJ and you told them, ‘Right, here’s a DoD contract. We need you to come up with an armor-piercing loading for standard 5.56 carbines that will go through and whatever they want to get, whatever they want to be able to defeat with the M7, with the 68 x 51. Give that standard to the guys at CBJ. Tell them they’re going to be doing it out of a 14.5 in barreled M4 carbine with a .223 chamber. And I’m willing to bet that they can they can do it. They’ve got 30 years of expertise developing, designing the small details that make so much difference on a project like this.”
  • That ammo is always going to be expensive, but not as expensive as adopting an entirely new battle rifle.
  • “Every new military weapon out there has some sort of whoopsie, we messed that up and we had to recall a bunch of guns and fix them. Like everyone in history always has it. It’s going to happen on the M7 if it’s not already. It’s going to happen on the M249 or the M250s if it hasn’t already. And all that’s incredibly expensive and I don’t think actually necessary for the goal of being able to defeat significant good armor.”
  • “If you put a tenth that amount of money into development of a 5.56 armor penetrating cartridge, you now have the ability to issue that really fancy expensive ammo when it’s necessary, or standard 5.56 ball and retain all of the benefits that we already have in 5.56 carbines.”
  • Then there’s the issue that most infantry soldiers aren’t really good at hitting anything out in the ranges the M7 is supposed to fill a need for. “And my concern with that is every time the US has gone into a war, they’ve ended up in the aftermath doing some research and trying to figure out what worked and what didn’t.”
  • “What is the effective range of an infantryman with a rifle? The answer that pretty much always comes back is 100 to 300 meters. At 100 meters, infantry are really good at hitting stuff with rifles. At 200 meters, they’re reaching their effective limit. And at 300 meters, it’s really rare that anyone’s doing anything very effective.”
  • Plus NATO studies showed “In 70% of cases, 300 meters was the maximum range that you could actually see a person standing up.”
  • “So when you consider all of the compromises that go into, and the expenses that go into, trying to generate a rifle that can give an infantryman a 600 meter effective reach out and touch that guy range, well, 70% of the time it’s a total waste, because the dude could be standing upright and walking around slowly with no idea he’s under observation, but he’s not under observation, because you can’t actually see someone 300 meters away when you’re prone.”
  • And that’s when someone is standing up. “Go look at footage from Ukraine and tell me how often are guys just standing up straight in the middle of nowhere.”
  • “Compromising a lot of the other capabilities of an infantry small arm in order to attempt to give the infantry a rifle that is effective at 500 meters, in my opinion, is a waste of time and it’s a really bad choice, because most of those infantry cannot make any sort of practical, effective use of that capability at 500 meters. They can do it to 200. The really good ones can do it to 300. And that’s where it falls apart.”
  • “It would be much better to maximize the effectiveness of the rifle within the the operational envelope that we know they’re really good in. Take a rifle and optimize it for one to 200 yards and go with that. Embrace that and then accept that you’re going to need other options for longer shots.”
  • Then take better marksmen and give them sniper rifles optimized for that role. “That’s absolutely well worth it. But what’s not well worth it is trying to turn everyone into the unit into that guy and in the process massively compromising their ability to maintain fire superiority because they run out of ammunition.”
  • And here’s the video that McCollum’s video references:

    In this video, you can clearly hear the Sig rep claim the gun was designed to withstand 125,000 psi. Like McCollum, I have my doubts…

    “Does The US Military’s New Combat Rifle Kinda Suck?”

    Sunday, May 21st, 2023

    Remember the U.S. Army’s Next Generation Squad Weapon, AKA the XM-5, AKA the XM-7, AKA 6.8 x 51mm? Brandon Herrera has managed to get Sig Saur to send him the prototype of the new weapon (the Sig Spear) to test, and…he has some reservations.

    The caveat here is that this is not an actual 6.8 x 51mm XM-7, it’s chambered in 308 Winchester/7.62 x 51mm (two calibers that are extremely close but not exactly the same), so the ballistics and operation are likely to be slightly different. (To make matters worse, the civilian version of the round is being marketed as 277 Fury. As far as I can tell from looking at Gunbroker, 277 Fury ammunition is available now, but models of the Sig Sauer MCX Spear chambered for the round aren’t yet on the civilian market.)

    Pros:

  • Short stroke piston doesn’t need a buffer tube, meaning that the gun can have a folding stock. “Actually pretty cool.”
  • Decent trigger.
  • “This little right side bolt release here. Kind of a fan. Feels a little flimsy, but I like the placement.”
  • Left side fold-out charging handle is good.
  • “Hand guard here offers a lot of space to mount whatever shit you want.”
  • Two gas settings.
  • Silencer works (even if not hearing-safe quality).
  • Likes the flat dark earth (FDE) finish. “In my opinion, it’s a pretty sweet looking gun.”
  • “Gun recoil impulse not bad.”
  • “Running it suppressed it’s not that gassy.”
  • Very reliable, at least over the initial 200 rounds.
  • The cons:

  • “It’s fucking heavy, dude!…Unloaded it comes in at 8.9 pounds. For reference that is one full pound, or 13% heavier, than a full-size SCAR 17, which is also a semi-automatic 308 with a 20 round magazine.”
  • Folding aside, the stock isn’t great and wants to slip.
  • “This charging handle in the back is borderline fucking unusable. It feels, really flimsy, like I feel like I’m gonna fucking break it. And it’s stiff. It is so
    fucking stiff! ‘How stiff is it, Brandon?’ Joe Biden in a room full of school kids.”

  • Potentially the biggest combat problem: Overinsertion of the magazine. “If you put too much force on the magazine when you’re inserting it, you will actually run up past the magazine release and get the weapon jammed.” Yeah, that sounds like a huge problem, and Sig needs to get that fixed ASAP.
  • The spring is a bit hard to get back in.
  • Super expensive right now.
  • From the comments on the video: “The fact that he’s actually able to unironically hold up a Scar 17 as a lighter, more affordable option is just batshit insane.”

    Yeah, looks like Sig needs some more work here before it’s ready to field…

    MiniLinkSwarm for March 25, 2022

    Saturday, March 25th, 2023

    For several weeks, I’ve been running out of time to post every link I’ve gathered, so I’ve been bumping some links (generally ones that seemed less time-sensitive or required more commentary than others) to the next week’s LinkSwarm, whereupon I may use one or two, but otherwise the process repeats.

    Well, I’m just going to post all those today to clear the decks.

  • California’s leftwing Democratic Governor Gavin Newsom is using his position as governor subsidize his wife’s own leftwing business empire.

    In the summer of 2022, Governor Gavin Newsom convinced the state legislature to provide $4.7 billion for K-12 mental health services, which, among other things, funded 10,000 new school counselors.

    Gavin Newsom convinced the legislature because Jennifer Siebel Newsom, the wife of the governor, convinced him. The biggest advocate for mental health funding within the K-12 California public schools in the Newsom administration was Mrs. Newsom, according to published accounts.

    In fact, Gavin Newsom created The Office of First Partner so his wife could promote her policy agenda using taxpayer money. Since 2019, Siebel Newsom’s been armed with nearly $5 million and nine staffers within her subdivision of the governor’s office.

    Snip.

    Siebel Newsom spent years laying the ideological groundwork and political infrastructure to support her policy ambitions.

    In 2012, Siebel Newsom founded a nonprofit, The Representation Project, that licenses “gender justice” films and curricula to 5,000 schools in all 50 states. The year Gavin Newsom became governor, the California Board of Education adopted guidance that recommended her films and curriculum be licensed and used in classrooms.

    Policy making in California isn’t magic. Turns out, it’s a carefully thought through process to maximize political power and personal return from public investments.

    Last week, we investigated the sophisticated scheme through which Siebel Newsom’s film and curricula “gender justice” nonprofit, The Representation Project, leverages taxpayer dollars to promote radical ideologies, personally profit, and push the political ambitions of her husband. She brags that 2.6 million students have seen the films nationwide.

    The Representation Project contracts with her for-profit film-production company, Girls Club Entertainment. Since 2012, Siebel Newsom received $1.5 million in salary from the nonprofit. Furthermore, since 2012, the Siebel’s nonprofit paid her for-profit Girls Club $1.6 million to produce films.

    Last month, our investigation broke the story that The Representation Project was not in compliance with the California Charitable Solicitation Act. The organization was not permitted to operate or solicit donations in California most of 2022 – yet spent all last year in operation and fundraising.

    Now, we dig deeper, investigating the $4.8 million “Office of the First Partner” Gavin Newsom established for his wife’s policy work, and how Jennifer Siebel Newsom used her position to impact social and political processes, cashing checks along the way.

    n 2019, Gov. Newsom created an office for his wife as a division within the governor’s executive team. According to a press release “the First Partner and her team will focus on lifting up women and their families, breaking down barriers for our youth, and furthering the cause of gender equity in California.”

    Since inception, Siebel Newsom’s office has received nearly $4.8 million in directed taxpayer funding. The Office of First Partner has grown from seven employees with a budget of $791,000, to nine employees with a budget of $1,166,000 proposed for 2023-2024.

    Snip.

    Parents have complained about the pornographic content in Newsom’s films shown to 11-year-olds (such as an animated, upside-down stripper with tape over breasts) and 15-year-olds (nearly naked women being slapped, handcuffed, and brutalized in images taken from porn sites) — to view images, viewer discretion is advised.

    Editorials have criticized the activities in Newsom’s film The Great American Lie as “emotionally abusive.” The activities ask students to publicly reveal personal information and force commentary on their relative “privilege” and “oppression.”

    So Jennifer Siebel Newsom is using California taxpayer money to propagandize children for radical social justice and transexism.

  • An Australian comedian, YouTuber and Journalist, made videos making fun of Australian politicians and covering their oppressive Flu Manchu lockdown policies. That’s when they started trying to use the state machinery to shut him up. Then they firebombed him.

    Jordan Shanks is an Australian comedian, also know as freindlyjordies, who fell in to doing YouTube videos about Australian politicians and powerful companies over the past few years. Along the way he became a journalist, the only journalist covering some of the things being done by the government and the corporations. Then in November of 2022 his house was firebombed. It was only by chance that he wasn’t in the house at the time.

    And hey, if that sounds too dry, well you kids like Knives Out or whatever. Stick around. It’s a pretty interesting whodunit.

    Most of the Australian press is even more in the bag for the powers-that-be than the US national media is for the Democrats. There were numerous stories, all but ignored by the mainstream. One example, the Premiere of New South Wales was under investigation. That was all but ignored by the press until she resigned. Then there were the antics of her Deputy Premiere, John Barilaro.

    That is the most entertaining — or damaging to powers that be — story friendlyjordies covered.

    As a result of that coverage, the Australian anti-terrorism machinery was directed at Shanks and his employees. Of course that turned out to be a group of Keystone cops, which got their own exposure on freindlyjordies. Along the way he exposed the abuse of the anti-terrorism squad, the relationship between some of the politicians and large corporations and perhaps organized crime. Then in November of the last year, after the lawsuits failed, the anti-terrorism actions failed, and the intimidation failed, someone moved to direct action, and tried to kill him.

  • You may remember my previous post on the army selecting the M5 Next Generation Squad Weapon. So how is that going? Evidently not well.

    On all key technical measures, the Next Generation Squad Weapons program is imploding before Army’s very eyes. The program is on mechanical life support, with its progenitors at the Joint Chiefs obstinately now ramming the program through despite spectacularly failing multiple civilian-sector peer reviews almost immediately upon commercial release.

    Indeed the rifle seems cursed from birth. Even the naming has failed. Army recently allowed a third-party company to scare it off the military designation M5. The re-naming will certainly also help scupper bad public relations growing around ‘XM-5′ search results.

    Civilian testing problems have, or should have, sunk the program already. The XM-5/7 as it turns out fails a single round into a mud test. Given the platform is a piston-driven rifle it now lacks gas, as the M-16 was originally designed, to blow away debris from the eject port. Possibly aiming to avoid long-term health and safety issues associated with rifle gas, Army has selected an operating system less hardy in battlefield environments. A choice understandable in certain respects, however, in the larger scheme the decision presents potentially war-losing cost/benefit analysis.

    Civilian testing, testing Army either never did or is hiding, also only recently demonstrated that the rifle seemingly fails, at point-blank ranges, to meet its base criteria of penetrating Level 4 body armor (unassisted). True, the Army never explicitly set this goal, but it has nonetheless insinuated at every level, from media to Congress, that the rifle will penetrate said armor unassisted. Indeed, that was the entire point of the program. Of course, the rounds can penetrate body armor with Armor Piercing rounds, but so can 7.62x51mm NATO, even 5.56x45mm NATO.

    The fundamental problem with the program is there remains not enough tungsten available from China, as Army knows, to make the goal of making every round armor piercing even remotely feasible. The plan also assumes that the world’s by far largest supplier will have zero problems selling tungsten to America only for it to be shot back at its troops during World War III. Even making steel core penetrators would be exceedingly difficult when the time came, adding layers of complexity and time to the most time-contingent of human endeavors. In any case, most large bullet manufacturers and even Army pre-program have moved to tungsten penetrators for a reason, despite the fact it increases the cost by an order of magnitude and supply seems troubled. Perhaps Army has a solution, perhaps.

    The slight increase in ballistic coefficiency between the 6.8x51mm and 7.62x51mm cartridges neither justified the money pumped into the program nor does the slight increase in kinetic energy dumped on target. Itself a simple function of case pressurization within the bastardized 7.62mm case. Thus the net mechanical results of the program design-wise is a rifle still chambered in a 7.62×51 mm NATO base case (as the M-14), enjoying now two ways to charge the weapon and a folding stock. This is the limit of the touted generational design ‘leap’ under the program. And while the increased case pressure technology is very welcome the problem is, in terms of ballistics, the round is in no way a leap ahead compared to existing off-the-shelf options as those Army nearly went with under the now disavowed Interim Combat Service Rifle program, or it in fact did purchase schizophrenically just before the NGSW program began with the HK M110A1.

    The Army is evidently still moving ahead with the program.

    I can’t tell you whether the criticisms are true or not unless Sig Saur sends me a example to shoot. While that would be cool, I suspect it’s pretty unlikely, and I fear many test ranges have picayune policies against using military grade automatic weapons…

  • How Georgetown Law cracked down on Flu manchu mandate heretics.

    For questioning Covid restrictions, Georgetown Law suspended me from campus, forced me to undergo a psychiatric evaluation, required me to waive my right to medical confidentiality, and threatened to report me to state bar associations.

    The Dean of Students claimed that I posed a “risk to the public health” of the University, but I quickly learned that my crime had been heretical, not medical.

    Just before I entered Georgetown Law in August 2019, I watched The Paper Chase, a 1973 film about a first-year Harvard Law student and his experiences with a demanding professor, Charles Kingsfield.

    The movie has the standard themes of law school: teaching students how to think, challenging the premises of an argument, differentiating fact patterns to support precedent. Kingsfield’s demands represent the difficulty of law school, and the most important skill is articulate, logic-based communication. “Nobody inhibits you from expressing yourself,” he scolds one student.

    “Nobody inhibits you from expressing yourself.”

    Two years later, I realized that Georgetown Law had inverted that script. The school fired a professor for commenting on differences in achievement between racial groups, slandered faculty members for deviating from university group-think, and threatened to destroy dissidents. Students banished cabinet officials from campus and demanded censorship of a tenured professor for her work defending women’s rights in Muslim-majority countries.

    Unaware of the paradigm shift, I thought it was proper to ask questions about Georgetown’s Covid policies.

    In August 2021, Georgetown Law returned to in-person learning after 17 months of virtual learning. The school announced a series of new policies for the school year: there was a vaccine requirement (later to be supplemented with booster mandates), students were required to wear masks on campus, and drinking water was banned in the classroom.

    Dean Bill Treanor announced a new anonymous hotline called “Law Compliance” for community members to report dissidents who dared to quench their thirst or free their vaccinated nostrils.

    Meanwhile, faculty members were exempt from the requirement, though the school never explained what factors caused their heightened powers of immunity.

    Shortly thereafter, I received a notification from “Law Compliance” that I had been “identified as non-compliant” for “letting the mask fall beneath [my] nose.” I had a meeting with Dean of Students Mitch Bailin to discuss my insubordination, and I tried to voice my concerns about the irrationality of the school’s policies.

    He had no answers to my simple questions but assured me that he “understood my frustration.” Then, he encouraged me to “get involved in the conversation,” telling me there was a Student Bar Association meeting set to take place the following Wednesday.

    I arrived at the meeting with curiosity. I had no interest in banging my fists and causing a commotion; I just wanted to know the reasoning – the “rational basis” that law schools so often discuss – behind our school’s policies. There were four simple questions:

  • What was the goal of the school’s Covid policy? (Zero Covid? Flatten the curve?)
  • What was the limiting principle to that goal? (What were the tradeoffs?)
  • What metrics would the community need to reach for the school to remove its mask mandate?
  • How can you explain the contradictions in your policies? For example, how could the virus be so dangerous that we could not take a sip of water but safe enough that we were required to be present? Why are faculty exempt from masking requirements?
  • I feared there were simple answers to my questions that I had overlooked: these administrators made hundreds of thousands of dollars per year, surely they must have had some reasoning behind their draconian measures. Right? The contradictions appeared obvious to me. The data seemed to be clear, but maybe there was an explanation.

    I delivered the brief speech without a mask, standing fifteen feet away from the nearest person. I awaited a response to my questions, but I realized this wasn’t about facts or data, premises or conclusions. This was about power and image.

    Arbitrary. Irrational. Capricious. Students learn in their first days of their legal education to invoke these words to challenge unfavored laws and policies. I figured that I was doing the same, and I thought the school would welcome a calm, albeit defiant, student asking the questions rather than loud and angry crowds.

    But this assumption turned out to be an incorrect premise. Nobody cared about my points regarding rationality – they cared that I had been reading from the wrong script. Even worse, not wearing a mask had been a more objectionable wardrobe malfunction than Janet Jackson’s Super Bowl performance.

  • Scrapped Railway Project Could Derail Putin’s Arctic Ambitions.

    Moscow’s ability to develop its own resource-based economy, expand the Northern Sea Route, cement ties with China and support Vladimir Putin’s ambitions to project power into the Arctic depends on the development of land-based infrastructure in the northern regions of the Russian Federation…

    Yet, that ability has now been called into question, as the Russian government has canceled, despite Putin’s repeated orders to the contrary, a program to complete the broad-gauge Northern Broad-Gauge Railway. The route was intended to link settlements that support the Northern Sea Route, military bases and the locations of key sources of raw materials across the Russian North with the rest of the country…

    Snip.

    What appears to be this project’s death knell, at least for the time being, is instructive in its own right. It occurred not with some dramatic single action by the Kremlin but in a rolling fashion as has often been the case with the backtracking of decisions under Putin. In April 2021, to much acclaim, the Russian president called for construction of the Northern Broad-Gauge Railway to begin, with the goal of completing the project in the next few years. Yet, despite Putin’s words, nothing happened, at least in part because of the COVID-19 pandemic, increased spending for his war against Ukraine and the impact of Western sanctions. Then, in 2022, Putin issued a new order for the project to go ahead. Again, nothing happened. Instead, less than a month later, Marat Khusnullin, a Russian deputy prime minister, quietly stopped all work on the project without giving anyone reason to think it would be resumed. Indeed, many Russian experts and commentators concerned with infrastructure issues believe that this railway plan has come to the end of its line, and one has even suggested that the cancellation of this project puts “a cross on the future of Russia.

    Russia was broke before it launched its illegal war of territorial aggression against the Ukraine. Now it’s even more broke.

  • Turns out I got through all but one…

    Update: 6.8 x 51mm Yes, TVCM No

    Saturday, May 7th, 2022

    In a previous post, I made the assumption that the army’s decision to go with 6.8 x 51mm for its Next Generation Squad Weapons (NGSW) program meant they had selected the True Velocity 6.8 x 51mm TVCM round.

    That appears not to be the case:

    About 3:40 in, he says the army choose not to go with the bullpup and it’s polymer ammo, so presumably TVCM is out of the picture for now. Instead the new round will use bimetallic steel-brass hybrid ammunition manufactured Remington. On the other hand, he says the “Lake City Ammo Plant” is in Utah, when it’s actually in Independence, Missouri, so some grains of salt are in order.

    If you have any additional information, leave it in the comments below.

    Is The Army Finally Ready To Pull The Trigger On 6.8mm TVCM?

    Saturday, April 2nd, 2022

    The light recoil of the 5.56 NATO round has helped make AR-pattern rifles a favorite of the civilian market, but the military has been looking for a rifle round with more punch for a while. Now they’re evidently moving forward with the replacement:

    Buried deep within the DoD FY23 budget request by weapon system, the US Army has officially chosen the contractor(s) for the Next Generation Squad Weapons (NGSW) program.

    NGSW is a prototyping effort by the Army that consists of a new rifle (NGSW-R) and automatic rifle (NGSW-AR), chambered in a new high tech 6.8mm cartridge, set to replace the aging M16, M4A1 Carbines and the M249 Squad Automatic Weapon, chambered in a 5.56 NATO round.

    The NGSW has been in competitive prototyping testing with three defense firms, including SIG Sauer, General Dynamics – OTS, and Textron Systems.

    On page 53/106 of the budget request, the Army expects to procure 29,046 NGSWs in 2023.

    “Starts funding for the procurement and fielding of 1,704 NGSW-AR, which is the planned replacement for the M249 Squad Automatic Weapon (SAW) within the Close Combat Force; Procurement and fielding of 15,348 NGSW-R which is the planned replacement for the M4A1 Carbine within the Close Combat Force; and procurement and fielding of 11,994 Next Generation Squad Weapons Fire Controls,” the document read.

    If I’m reading that correctly, the “new high tech 6.8mm cartridge” would be the 6.8mm TVCM, which uses a polymer case rather than brass.

    Supposedly the round is compatible with a wide range of current weapon platforms with just a barrel swap.

    The hybrid polymer-cased cartridge, developed by Texas-based True Velocity as part of the Army’s Next Generation Squad Weapon program, is compatible with legacy firearms as well.

    The 6.8mm TVCM composite case design, coupled with the Army’s 6.8mm (.277-caliber) common cartridge projectile, was originally developed and optimized for use in the NGSW-Rifle and NGSW-Automatic Rifle submissions submitted to that military program by General Dynamics-OTS.

    However, using what True Velocity characterizes as a “switch barrel” capability, they have demonstrated it can work with much of the Army’s currently fielded small arms including the M240B belt-fed machine gun, the M110 semi-automatic sniper system, and the M134 minigun.

    Here’s a video of test-firing the ammo in an Assault Machine Gun.

    Next Generation Squad Weapon will also be using an on-weapon ballistic computer integrated into the optics:

    “The new optic has a integrated laser range finder, wind sensor, temperature gauge, elevation sensor, and ballistic computer all rolled into one.” That is likely to be a huge boost to troop capabilities, assuming it works as planned. Like any piece of technology, expect a shakedown phase where they work out all the bugs.

    True Velocity hails from Garland, so mark that down as another win for Texas.
