I just got a PSAk47 not too long ago. So far with about 800 rounds down the tube no problems. I did change the trigger out to a G2 which is far better than the original IMO. Some time in May we will attend a semiannual pig roast where a lot of shooting goes on. In the past events my Romy (a real great beater) has gone through a thousand rounds in one day. I intend to use this PSA AK this year.
It's not a 10,000 round endurance test but if it doesn't screw up in a thousand rounds in a half a day, it should be good to go for anything you want to do with one.
The PSAK is a bit short for my 6'4" frame so I put on a removable butt pad that gives it a 1" etension. Makes it more comfortable to shoot.
FWIW, I put a cheap optics mount on with a TRS25. (Hey, it's a fun gun, not a business tool) My FIL had to shoot it when he saw me busting a plastic soda bottle at 60 yards with every shot.
With Golden Tiger ammo , this PSAK is on a par with my Polytech Legend and Galil as far as accuracy at informal shooting.
