You can pour sand in the receiver of the Galil (an AK-47 variant) and it’ll still fire. The Israelis do carry M-16s but they weren’t really designed for that environment.
Yeah but AK variants achieve their reliability by having really loosy-goosy tolerances - which wrecks their accuracy. I see AR variants routinely hitting 300+ yard targets at my local range - never seen it with an AK.
Precision with a stock AK is not going to happen.
