A perfect example of why suppressors should be non-NFA items. Even ignoring costs, civilians are not likely to be much of a factor in this new rifle/cartridge demand because of the pita factor. You get caught shooting this gun without ear protection, you better learn sign language.

Y tu? .277 Fury is also called 6.8x51mm, makes me wonder if running a 308 win in a .277 Fury die will do it.
Maybe if you can get enough people to boycott, ATF will give in.

Looks like the idea's been around for a while. Here's an interesting thread from a different forum in 2007. https://thefiringline.com/forums/showthread.php?t=238342

Yeah it's been around. I think Ken Waters had some loads in his book.

Its going to be the PSI problem, most civilian guns will not handle the PSI and reloading will not happen right away- need to supply army first so it will be some time and brass cost $$$$$ for a while anyway. Besides its just another TOY- Right !!!!! As mentioned above get a 6.8 SP or a 270.
Right now price of ammo for this is $17-19 a military round until they scale up. In theory it's supposed to penetrate a level IV stand alone plate out to 400-600meters. The goal posts have been moving so
The difference between civ and mil ammo will likely be bullet.
I'm a little surprised that no one's mentioned the GD-OTS / Lone Star bullpup. If I was interested in buying one of these guns, that's the one I'd choose.

But I think that figure was from a 16" barrel.

Lot of "wrong" in this thread. Here's some facts:
1) Cartridge is the same whether you call it 6.8x51MM (military) or .277 Fury.
2) 80,000psi IS (and has been for a couple years) the SAAMI approved spec for the round.
a. This pressure requires the three piece composite case (steel case head, brass case body, and locking ring to hold them together.)
b. The all brass cased version of the ammo runs at "normal" pressures.
c. Both are because the weak point at 80,000psi is the casehead and primer pocket in brass.
3) 3,000fps is 135gr bullet (military designed projectile with penetrator) from a 16" barrel.
4) Military set a spec for barrel life of twice the "useful life" of a current M4 barrel. (Which basically means how many rounds sent downrange before the weapon will not shot 4MOA or less.) For an M4, this is ~6,000 rounds. 6.8x51 military barrels use a nitriding process instead of the M4s chrome lining (and some other changes) and have gone ~14,000 rounds before accuracy falls out of required spec. What that means for aftermarket civilian barrels in terms of useful accuracy life is anyone's guess. That said, SIG has stated that all barrels it produces for this round, including for the Cross rifle, are built to the military standard.
5) SIG has stated that the composite case is "currently not reloadable" but that "they are working on it". Issue appears to be how to resize the steel case head without possibly compromising the locking ring. When you consider 80,000psi, failure of the locking ring would be a bad thing.
FYI - All of the above is public knowledge reported by Soldier Systems Daily and others who closely follow the military.
Note: I have no affiliation with SSD or SIG. I'm just ex-Army and a gun nut who has been following this process for years.

Yeah, but we will not be able to purchase the 6.8 military ammo. Sig is going to release a "civilian" version of the 6.8, the .277 Fury according a press release I saw yesterday.
