Get extra Hammer Springs for your ARs

The firing pin seem to go about 10,000 rounds. I did recently find one broken in half, but still working because it runs inside of a channel.

The gas tube seems to be doing fine. It only came loose on 1 rifle when I first bought it. After that it has stayed in place. I do get my guns hot, but not all the time and when they usually get too hot to hold, I switch out to another gun rather than wear gloves.

I just killed the barrel on one of my ARs with 22,000 rounds. The bullets are going sideways at 50 yards. Rifling now looks gone. I did an accuracy test just a few months ago when it had about 20,000 rounds on it and it was still shooting 2 inch at a 100 yards. So the drop-off was very sudden over the last 2000 rounds. I'm planning to do a video just on this.

Makes sense, have you shot out any barrels yet? Just wondered how many rounds that actually takes. I think it would be quicker if it stayed hot. Still I’ve never seen one shot out on an AR anyway.

Thanks good info to know. I’ll be looking for that video
