>i would say AR15s ARE true direct impingement because there is no piston spring or any sort of system that attaches the gas key to the bolt on a AR15 it is directly connected and part of the bolt carrier
>so in my opinion the gas is still directly IMPINGEING on the bolt carrier

oh wow i guess i was wrong and dont actually know how the inside of a AR15 bolt works
whoops i just assumed the gas key was solid and directly made the bolt push backwards
like they say though ASSuMING makes a ASS out of U and MING
