Rex, my guns functioned flawlessly, and if I said how much military ammo I ran through the .223 and .308 versions people would be surprised. I will say that if somebody was dumb enough to do cowboy action shooting with these, they might screw them up. But they are hunting weapons, not gaming or military rifles. I do not imply that they are delicate. Mine, if scoped, would shoot at least 3 inch 5 shot groups at 100 yards for me. Note I said for me. I am not a rifleman. Anyway I spent most of my life shooting rocks, stumps, hogs, and stuff. As a concerned sportsman, I would not shoot at an animal past 150 yards anyway. He who takes one apart will not get it back together.
