Good news for bullpup fanatics: The Lithgow F90, Australia’s improved version of the AUG, is in production in the USA right now under the name “Atrax”. Representatives of Dasan USA, the stateside manufacturer/importer, said that major components of the Atrax, including the barrel, were already being produced in their facilities within the country, to allow production weapons to comply with US import laws. Dasan Representatives said that the technical data package for the US-made components was transferred to the US from Australia, so each component made in the States adheres exactly to Lithgow’s methods and standards for that component.

At an AUSA breakfast conference yesterday, US Army Chief of Staff General Mark Milley gave us a hint at exactly what the US Army’s next rifle could look like, and the focus was on extended range capability. The rifle, Milley said, will give a 10x improvement in capability through the type of ammunition, optics, and degree of chamber pressure specific to it, with the aim of providing the soldier a weapon with much more accuracy and range than the current M4 Carbine. Milley also clarified that the term “10x” was not intended to be a precise measurement of the capability growth, but rather a term indicating significant improvement. The new rifle will come as part of an effort that also includes new artillery, tanks, aircraft, and virtual reality training facilities, Milley said.

Canton Ohio custom gunmaker Middlebranch Machine has released a teaser image of a new kind of suppressor, which they say is made of “carbon fiber composite” construction. Unlike previous efforts at making carbon fiber suppressors, Middlebranch Machine’s design does not seem to use a straight carbon-fiber tubing body, but appears to be 3D printed, instead. This is strongly suggested by the background of the image which shows a customized Glock with a unique looking suppressor in front of what is probably a Markforged Mark Two carbon fiber 3D printer. Mark Twos are some of the only carbon fiber 3D printing machines in the world.

Recently on The Firearm Blog we talked about one of the great might-have-beens, the German caseless G11 rifle developed by Heckler & Koch during the 1970s and 1980s. Today we have a video from 1990 filmed at Aberdeen Proving Grounds of a demonstration of the G11K2 on the firing range.

Is the US Army pushing for a new high-powered 6.Xmm caliber with their new NGSAR program? Recently, the listing for the NGSAR industry day in December was updated with a document describing in part the agenda of the second conference. Scheduled for 9:45 in the morning in the document is a 15 minute long presentation on “Ammunition Data – Surrogate Projectile and Specs”, presented by Todd Townsend, David Charowsky, and Mark Minisi. Minisi’s name may not be well-known, but it will be familiar to astute students of recent wound ballistics literature: It was Minisi who developed the finite element analysis-based tissue damage model, which has been refined over the past decade at ARDEC through PM Maneuver Ammunition Systems (PM-MAS). Mr. Townsend is also likely representing PM-MAS, now under the leadership of Colonel Hector Gonzalez. 

In the comments section of my recent Brief Thoughts article regarding caseless ammunition, there was a discussion about whether the cookoff issues of caseless would also be problem for LSAT-style polymer cased telescoped ammunition. Based on conversations I have had with subject matter experts regarding polymer cased ammunition in general, I noted that a lower cookoff threshold is one of the challenges I would expect CT ammunition developers to face. However, after some back-and-forth in the comments, I decided to contact LSAT/CTSAS program officer Kori Phillips regarding this issue (as it was not something I covered in my three-part interview with her), and she kindly agreed to allow her comments on the matter to be published here on TFB. They are below:

In the world of “might-have-been” small arms, a world of .276 Garands and NATO-standard EM-2s, none flew so high nor fell so far as the Heckler & Koch G11 caseless hyperburst assault rifle. Designed to out-match any contemporary small arm in a Cold War shootout across Central Europe, the G11 combined the aesthetics of a scifi plasma rifle with complexity of a Swiss watch. The result was a bullpup caseless wunderwaffe with a 2,000 round per minute hyperburst setting, and a price tag that, as the joke goes, compared unfavorably with reconstructing East Germany.

Caseless: The ammunition designer’s holy grail, and the engineer’s worst nightmare. It would obsolete the cartridge case overnight, resulting in cheaper, lighter, and more compact ammunition. Weapons would be able to carry 50, 60, or more rounds in slim, inexpensive magazines, and expel them at a rate of fire much higher than current weapons are capable of – not only because the ammunition is lighter and therefore more could be carried to feed such thirsty guns, but because the extraction and ejection cycles of the weapons themselves could be eliminated.

Working under contract from the Army’s Research, Development, and Engineering Command (RDECOM), AimLock, a subsidiary of Rocky Mountain Scientific Laboratory, developed an actively stabilized weapons chassis for AR-15 rifles. AimLock has been in the news before for their stabilized rifle platform, which was shown off in a presentation at the 2016 National Defense Industry Association conference and subsequently reported on in Futurism and Popular Mechanics, and, of course, here at TFB.

In the coming decades, it is likely that one of the biggest challenges facing small arms ammunition designers will be solving the problem of how to deal with advanced body armors. The problem is already percolating to the surface, as Level IV body armor – which is immune to virtually all general issue rounds below .50 caliber – becomes more available and less expensive. Already, an individual can equip themselves with a full set of Level IV plates and a carrier for less than $1,000. As armor improves, it will only get lighter, cheaper, and more resistant to fire.

We have already seen the 6.5mm CT Carbine prototype brought out by Textron for the 2017 Association of the United States Army annual meeting, but TFB also got an up close and personal look at Textron’s cased telescoped machine guns. Textron has two different cased telescoped belt fed weapons in testing right now: A 5.56mm CT light machine gun, and a 7.62mm CT medium or general purpose machine gun.

General Dynamics Ordnance and Tactical Systems (GDOTS) brought their .338 Norma Magnum caliber Lightweight Medium Machine Gun (LWMMG) to the 2017 Association of the United States Army (AUSA) annual meeting, giving TFB the chance at a closer look at this much-anticipated long range weapon.

At the 2017 Association of the US Army (AUSA) Annual Meeting, Textron System displayed for the very first time their firing 6.5mm CT Carbine prototype. Previously, only non-firing mockups had been shown to the public, but after successful tests this summer the real thing was brought out to show at the conference, where TFB got its first look at the weapon.

Yes, you don’t own a flying car, but at least some of the promises of the future are coming true: The United States Navy has successfully tested its railgun prototype in multi-shot (autoloading) mode, earlier this summer. Although the US Navy has been testing railguns since 2006, this latest test was the first time such a weapon had fired multiple shots in quick succession, thanks to an autoloading mechanism fitted to the rear. You can see the railgun in action in the video below, released by the Office of Naval Research:

The traditional wisdom goes: Lightweight or “pencil” profile barrels can shoot great – just so long as you don’t get them hot. After a mag or two of heat is dumped into your lightweight build, your point of impact (POI) will probably shift by several minutes of angle. If you don’t like it, then you’d better go for a thicker profile or learn your holdovers, because that’s just a fact of life with pencil-thin tubes.
