View Full Version : same old AR questions... piston retrofit??

December 25, 2010, 05:05 AM
i know im probably betting a dead horse here but here goes.

i like to tinker with stuff and while i dont feel that a piston operated ar15 is any better than the gas impingement system, i would like to try it out none the less.

what i gather is that the 'long stroke' is better than the 'short stroke'

the question... any suggestions on what i should try? best for the money (i dont want to spend more than $350)

what have you tried? what do you suggest?
