Adams Arms piston kits... On Grendel?

[noobshooter]

Like montana, I have 3 Adams Arms Piston systems. One in each length: carbine, mid, and rifle. The Mid and Rifle length ones are on two Special Purpose Rifles (SPR) in 5.56. They are as accurate as my other gas impingement SPR. So no difference in accuracy. No issues with buffer tube wear as Adams Arms BCG are designed to eliminate the cant of other piston BCG. Hell, the Adams Arms BCG has an angled bottom end at the rear of the BCG just in case.
