Some pretty broad assumptions by some on this post concerning what type of ammo we shoot in our sub par it's going to fail between 100-1000 rd AR's. As of now I put 500rds of through my subpar AR. No FTF, no FTE, etc. I have yet to shoot any cheap ammo through it. All been handloaded 75's, 77's, 80's, 88's and 90's. I will be honest my rifle with a 10 shot group is a honest 1.2-1.5 inch rifle at a 100yds. Just shot a 10 shot group this evening 1.2 or so inch. I don't bother posting pictures anymore. I have nothing to prove to any of you yahoos. I do know if I want up my game for the AR tactical or Service rifle competitions I need to get another barrel it will probably be a WOA barrel. But for the average guy shooting orange clay pigeons on the burm inch and half rifle is just fine.
