Anyone else out there have a 22a with any problems? I have had to replace my recoil buffer 2 or 3 times, Probably due overuse(ha-ha) before 22 ammo got so scarce. I probably ran 12000 to 15000 rounds thru mine. I had to replace the firing pin 1 time. replace the mount for the firing pin/spring once. and the firing pin spring once. Not to bad for a very well worn in 22 semi-auto.
