Same as some other people, mine isnt just a range toy. I have abused it just like it should be abused. Hard and like a whore. Ha kidding, but I don't baby it. I take it hiking with me, it guts dropped and kicked (by accident) and banged around (trees and what not while slung) I have never had a stoppage, except some ftf from norinco ammo. I think 3 in total out of 3000ish rounds. I don't gently seat mags like some guys I see doing (I really don't know what they are trying to prove but ok) not slamming them in but I'm not gentle either. When I practice IA drills at the range I smack the #### out of the mag when I'm doing a look tap and rack drill. The gun has never failed me at all. Out of the three ftf I have had they were all hard primers. Ammo fault there. And I swear it doesn't like being clean, it likes to perform well when it's dirty.. I just don't get it lol.
