One of my AR's has started giving me issues. This is a built gun, not a budget gun but not top shelf either. It's a 300 blackout with out suppressor. This gun has been running fine for years. But recently started giving me issues. I will try to explain it the best I can. Your first round is loaded manually by closing the bolt. It fires and ejects just fine. The new round gets loaded and everything appears to be fine. But it wont fire. You pull the charging handle back and it ejects the second, unfired bullet. You drop the bolt and it manually loads the third round and she fires just fine. The trigger wont pull on some of the auto loaded rounds, sometimes it will but there will be a slight mark on primer. Gun fires just fine when manually loaded by you. But the auto loads will not.
I have swapped mags, that didn't help. Changed bullets, nope. I do not run handloads, this is all factory rounds. Bumping the rear of charging handle and pushing the forward assist does nothing either.
Can this be a firing pin problem?
A gas block problem?
Or maybe a bolt carrier problem?
Any ideas?
Thanks,
Matt
