I bought one back right before Hillary was President just to have one. Bought 1000 rounds, shot maybe 150. I heve to think about the safety, mag release, etc when I shoot it. That thousand rounds will probably last me the rest of my life. Age 64I mean if we are being realistic I would say most civilian owned AR's never see 500 rounds much less 1,000 especially with ball ammo being 75¢ PR
I also have a SW MP .22 which we do shoot a bit. I’ve had no issues with either one but have certainly not given them any kind of stress test. I’m much more into handguns I guess.
