Have a new-to-me AK that is giving me problems. Today was my first time out with it and the first 10 rounds fired flawlessly, then every second or third round thereafter would fail to fire. The trigger would reset and a new round would chamber, and the ejection of the prior round was 15+ feet. After giving the rounds time to "cool down" after failing to fire they were ejected and carefully shot again, they worked without issue their second time through. I know this probably is not recommended, but every single round fired within two tries, so it wasn't just bad primers.
I noticed a few things though... depending on whether I pulled the trigger and held it back, or if I pulled the trigger and got my finger off of it as soon as possible, sometimes I could get off a few more rounds before having a ftf.
When letting the bolt carrier fly, it does not bind up, but if you let the bolt carrier ride slowly, it has the potential to bind (right around the hammer area).
The ammo worked fine otherwise.
The firing pin did not seem to rattle, but it was free to reciprocate in and out of the bolt. I added some oil and cleaned it and made sure to empty it of fluids, but I didn't have any punches to remove and examine it. The tip of the firing pin was not sharp, it did not have appear to have sheared off. I may buy another one to try that.
This is a Tula build (beautiful, not a joe schmoe build) but I did get it on a trade. It's on a Nodak receiver.
Any suggestions or first suggestions?
These are just some of the rounds ejected by hand.
Here's the bolt binding on the FCG area:
Here's an individual round.
