US Army Adopting 6.8?

I just read that the US Army was adopting the 6.8 (replacing 5.56). Is the confirmed or another study?


Doesn't look like the 6.8 SPC...

https://www.thefirearmblog.com/blog/...omatic-weapon/

Update, the U.S. Army recently awarded five companies contracts to develop a prototype weapon intended to replace the 5.56x45mm M249 Squad Automatic Weapon.
The companies are:
AAI Corporation Textron Systems – Hunt Valley, MD.
FN America LLC. – Columbia, SC.
General Dynamics-OTS Inc. – Williston, VT.
PCP Tactical, LLC – Vero Beach, FL.
Sig Sauer Inc. – Newington, NH.
The caliber and type of ammunition is up to the companies and it is reported that most are using the government provided 6.8mm projectile. The ammunition must weigh 20 percent less than an equivalent brass case ammunition.

That is a study. They award money to fund development and production of prototypes for evaluation. It is commonly done for everything from backpacks to helmets. Usually, this is like seed money to keep the potential vendors in the game.

In all likelihood, no caliber change is likely without NATO allies being on board. And without a caliber change, a platform change is not justified unless the current inventory is aging and in need of replacement anyway.

However, the caseless and telescoped ammunition ideas have been kicking around for a while in one form or another as a weight and volume saving. If they can implement something in 7.62 and or 5.56 that can be used in existing guns as well as next generation, who knows?

More wasted tax dollars.


6.8 is better than 5.56 in many ways.

That is really old news from way back in June. Apparently they are going to make a new solicitation

Doubt it will happen anytime soon, if at all. These thing are for research and development, this allow companies to innovate and the government to understand what the future may hold. It is not necessary wasted tax dollars.

Sadly this will cost lives. Rounds that generate the chamber pressures and velocity they are seeking will lead to extraction issues and massive throat erosion.

Then they will issue these harder recoiling and heavier systems to female combat troops.

It has been my experience that technical knowledge of the subject is not required to be in upper level military R&D and procurement.

Don't worry, there is about a 95% chance this won't go anywhere. The Army does this sort of thing pretty regularly. The new M855A1 is pretty good but the officers need their OER bullets. You don't get those for an attitude like "if it ain't broke, don't fix it."

6.8 after the 1st Gulf War. 300 Blackout later. Several different cartridges (all the "in" wildcats for ARs that have come and gone over the past 20 years). Potential replacement carbine studies. Caseless ammo. Piston rifles. Bullpups. Where's the future going to be type stuff.
It's just studies, always going on. People reinventing the wheel thinking their 100 year old idea is new or they know better than the last selection committee. Seldom results in anything.

I don't see the big deal about 6.8 and I never have. 6.5 Grendel seemed cool because it was pretty good at decent ranges, but that's not a common encounter. 300 BO can do all that a 5.56 can do at 0-200 except with an 8" barrel and can use subsonic too, but it ain't great past that range. .308 is just too much recoil for rapid shooting. All of them are pretty heavy to carry.

I think the best option would be just to make 77gr ammunition standard issue, then 5.56 can do just about anything needed. Better terminal ballistics, better long range capability.

Edit: I didn't realize this was for the M249 at first.
