A buddy of mine has a new AR in 6.8 SPC that will fire and eject empty cases fine, but wont strip a new one from the magazine. He thinks it's a problem with the gas block, however my first thought was problems with the mags. He's tried three different brands of mags, and this is all with factory ammo. I have zero experience with this cartridge in the AR, anyone have any thought/advise?
Thanks,
Shooter.
