“with a gas piston”

As Travis has already pointed out, that gas piston cycling leads to a major recoil affect with a bump in the sight picture the AK suffers from. The AR platform is smooth shot from shot and leads to very quick follow up shots. I know of no gas tub failures such as that a piston is needed. That gas tube unlocks the bolt every time and no piston would do better.

Somehow HK figured it out. SOCOM seems to like the 416, which is not much more than an M4 with a gas piston.
