The Sig Sauer 6.8 x 51, is a piston driven, heavy and very expensive rifle.

The ammo is heavy, very expensive and difficult to make.

With the military getting rid of strong male warriors, in favor of DEI personel, that won't be able to shoot or carry this rifle, it appears to be an expensive boondoggle.

There are piston ARs; Adams Arms, POF and they come in any caliber.

Adams Arms sells a kit for $200 that can switch any DI AR to piston.

Heck, they can switch the caliber, on existing rifles AND switch to a piston for a fraction of the cost of these Sigs.

They went to the new Sig M7, 9mm last year.

The 6.8SPC can be fired with a barrel and bolt swap. I didn't buy in as 6.8SPC was a "boutique" round that was seldom stocked. There is also a spec for 6.8SPC II that must be assembled as a pair (barrel/bolt). Either SPC or SPC II can fire 6.8SPC cartridges, but barrel/bolts are not interchangeable.

The new SPC spec that goes in the Sig configuration is a much higher 80,000 PSI chamber pressure, so expect yet another flavor of SPC bolt/barrel that can handle the higher pressure.

I have some 6.5 Grendel (same goofy issue with two different barrel/bolt specs). The Wolf 100 gr 6.5 Grendel works Ok. Steel case. I've had one split case thus far. A real pain to extract from the chamber of my CZ bolt action rifle.

Hey we don't do cheap boondoggles 6.
