SayUncle reported that Bison Armory are selling new 6.8 SPC AR-15 upper recievers. From BisonArmory.com:

We just got our 18″ and 20″ 6.8 SPC barrels today! I’ve put together the first upper for testing. It’s a 20″ with unthreaded muzzle. Pictured below is the upper with a Young Mfg. Match bolt carrier, YHM lightweight four-rail rifle length hand guard, and YHM A3 flat top upper receiver. The upper also features an intermediate-length gas system, YHM low profile gas block, and YHM forearm end cap.

These photos of the uppers were posted on 68forums.com:

The first upper is the most basic, 20″ with threaded muzzle, Phantom .308 FH, Bushnell 3-15×50 scope and rifle length gas system. The second one is the 20″ unthreaded with intermediate-length gas system.

The first upper in this photo is an 18″ with a Saylors Machine Phoenix FH and mid length gas system. The bottom one is an 18″ with a TNW gas piston system and DPMS Levang linear compensator. I’m really looking forward to trying out the GP system.

    If you buy an 6.8mm SPC upper, then what recoil spring an buffer do you use in the lower receiver? Please email the answer to Dan Grahan at dangraham@grahamcommercial.net.

    You don't want chomre if you can find one without it. The barrel can be broken in and shoots a tighter group with non chrome lined barrels and chambers.
