The PSA premium one would probably even be an improvement if you don’t want to pay the $150ish for a better one. If that’s too much, go to BCM’s site and buy as many of their BCG components as you’re willing to spend money on. Obviously firing pin first, but the SOPMOD rebuild kit is probably a good idea too, even a bolt if you’re up for the $70 tag. Your use should not have caused that to happen if all of the parts were in spec, dry fire or not.
