Hay i'm looking to do a ar build and i was thinking of using a 6.5 Creedmoor gas piston. has anyone tryed this? and where can I get parts?
we've done gas pistons in 6.5Grendel and gas guns in 6.5Creedmoor & 6.5Grendel - both suppressed and unsuppressed.
choada running his 6.5CM:

I love mine glad we built it. Great shooter. We have only reached it out to 650 yards here someday hopefully get it out double that.
Some of the parts are Armalite upper/lower, geissele trigger, DD rail, brux 1/8 barrel heavy, PRS stock, FDE cerakote, USO SN3 5-25x56, YHM phantom can, etc
