I have 260 rounds thru my AK-P... the rear end of the ejection port is slightly chewed up because of steel cases winning over aluminum dust cover. Unsure if it is a fluke, or specifically my gun being over-gassed. I have been in contact with PSA, and they want to ship it back to be looked at.
I like the gun, and it is very well setup. In regards to SBR... I bought it to be a pistol (legally allowed to be loaded in my truck, due to carry permit/LEOSA). If powers decide that braces are stocks, I'll probably SBR/SBS my guns... hell, they know where I live due to the three suppressors I'm waiting for the Form 4s to come back on. But if I go thru the hassle for that (wait, tax stamp, engraving), I'll put stocks on them.
I wanted to toss my Bushwhacker 46 on it, but depends what happens in regards to its trip back to PSA.
