its a real, actual HK 91, with only like 40 rounds thru it. apparently you can just buy the auto sear mechanism. they have milsurp from Germany. it wont drop in, needs some machine work but you can just buy those parts obline

as far as utilitarianism an AR10 is WAAAAAAAY better, man. this thing punches you in the shoulder with that roller delay mechanism. and its not lightly either. it slugs real good, it's heavy.

there's no provision for pic rail, accessories anything, its all gotta be modernized. the optic is on with this adapter claw that bites the receiver, i don't trust to hold zero

for the coolness factor yeah HK G3 is tits mc gee, but you can get yourself something a thousand times better, prob with a better barrell too
