Some of the recoil control of the NGSW may come from the new Muzzle Device called the 'Smuzzle':

https://soldiersystems.net/2020/07/23/the-smuzzle-the-armys-latest-invention-combines-a-muzzle-brake-and-suppressor/

Engineers at the U.S. Army’s CCDC Armaments Center have designed a firearm sound suppressor that incorporates the features of a high-performance muzzle brake

The Smuzzle’s flow-through design features asymmetric venting through tiny holes which researchers claim results in a 50% drop in volume at the shooter and a 25% reduction in the flash signature downrange with a minimal weight increase. They also incorporated a feature they refer to as a “bottom blocker” which reduces how much dust is kicked up.

This weapon was used by Army researchers to establish a baseline during the early stages of the NGSW program. It’s important to note that this demonstrator was manufactured by Textron and based on years of development under the Lightweight Small Arms Technology project of the Joint Service Small Arms Program.

Its refinement has included the use of sophisticated engineering techniques including computational fluid dynamics modeling and the center’s state-of-the-art testing equipment.

Federal has recently received a contract for the 'Next Generation Carbine Technologies  Program" - something I had never heard of before. This is either part of NGSW, or some sort of parallel program. 

https://soldiersystems.net/2020/07/31/federal-awarded-high-performance-ammunition-contract-for-us-army-next-generation-carbine-technologies-program/

Federal Ammunition is proud to announce a contract award to supply high-performance 7.62x51mm NATO and other novel ammunition for the U.S. Army’s Next Generation Carbine Technologies (NGCT) program. This suite of ammunition utilizes a specialized alloy cartridge case allowing for elevated chamber pressures and a reduction in ammunition weight as compared to legacy brass-cased ammunition. These performance benefits deliver a significant increase in overall weapon system effectiveness for the NGCT program.

“Our use of a proprietary high-performance alloy cartridge case will provide the U.S. Army NGCT Team with an excellent ammunition platform for evaluation of advanced Next Generation weapon concept performance. Program results will serve to inform the direction of future Next Generation weapon technology decisions for the U.S. Army,” said David Leis, Federal’s VP of Law Enforcement, Government and International Sales. “Ammunition products utilizing this specialized alloy cartridge case technology will be made available for commercial and foreign sales in the near future.

The only info I could find on NGCT is page 6 of https://ndiastorage.blob.core.usgovcloudapi.net/ndia/2019/armament/Rice.pdf

This is probably related to the LWC SAA program, and my guess is that's the stainless steel/aluminum composite design by GDOTS Canada, tech transferred to Federal. I have no evidence for this, but the Army was very interested in this design three or four years ago and it's likely they see it as a "backup" to some of the more ambitious NGSW designs. GDOTS Canada being Canadian, and GDOTS being a competitor in NGSW, it might make some sense if this were tech transferred to Federal. But I really don't know, it could be Shell Shock, or something else.

https://soldiersystems.net/2020/08/05/true-velocity-delivers-next-gen-6-8mm-ammunition-to-us-army/

August 4, 2020 GARLAND, TX – True Velocity officials confirmed recently that the Texas-based technology company delivered more than 170,000 rounds of its 6.8mm TVCM lightweight ammunition to the U.S. Army in May as part of the Next Generation Squad Weapon (NGSW) program.

“As a team, True Velocity is excited and proud to have delivered this significant order of next-generation ammunition to the Army in-full and on-time,” said True Velocity President Chris Tedford. “Our 6.8 TVCM composite-cased cartridge is capable of unprecedented ballistic performance, while simultaneously exceeding the Army’s expectations in terms of weight reduction.”

“True Velocity’s ammunition – and particularly our 6.8 TVCM cartridge – are changing the paradigm,” Tedford said. “It turns out you don’t have to operate at unsafe chamber pressures in order to generate increased velocity, enhanced terminal performance and improved accuracy. Our cartridge achieves all of these things, while maintaining safe operating pressures and drastically reducing the overall cartridge weight.”

--> This seems to further confirm our guess that the TV case is not a high pressure loading.

???  I don't see where the PR statement divulges what the pressure is.

The safety of firing depends on ammunition and weapon. I suspect if you rebarrel, say a 93 Mauser in 6.8 Bleedmoor, unsafe things will happen.

General Dynamics seem to have dropped out of NGSW, passing their contender over to "LoneStar Future Weapons".  Not a good sign?

Tony, I cannot imagine other explanations rather than a withdrawal of GD. If they have meaningful opportunities for success in NGSW, they wouldn't do such a thing.

Do you think that SIG has any serious chance against textron's CT entry?

I would dare to affirm that now NGSW just need to decide if Textron is enough mature or not

GD hasn't withdrawn at all.

Lonestar was essentially ADDED to the GD / True Velocity team!

Some of you may have recently seen that true velocity showed their 6.8 ammo being tested In a knights AMG this January. 

What we DO KNOW is that the NGSW program is very heavily interested in having belt fed weapons also chambered in the 6.8 round they wind up choosing.

This has been a weakness of the GD submissions all along and bringing in lonestar to handle POST DEVELOPMENT means that they will be responsible for helping to manufacture and evolve the existing GD TV submissions as well as bulking out their lineup.

I don't know how anyone could read that press release and decide that it really means GD has dropped out of the competition... I just genuinely can't comprehend how that would be the message someone took from this.
