I've got this virgin barrel Bulgarian AK74 build that has me worried.
It runs fine. No issues feeding or extracting and ejecting.
The empties go flying into orbit as expected.
The primers on those empties have a distinct raised rim around the primer crater.
And it looks like the primer is starting to back out.

The bolt face looks good, and the bolt lugs have no peening or deformations.

The barrel headspaces perfectly both with and without the carrier.
The barrel is a new Bulgarian cold hammer forged barrel from K-Var, and the kit came from R Guns.
I used an oversized pin for the barrel pin.
