Amazing

by

This device is amazingly rugged. Even with brute force and pliers banging up against it on accident.Just be sure to clean up the firing pin hole. Also, clean up the hole for the cam pin too! There may be excess carbon from testing. If you got the NiB-X cam pin, it's a super tight tolerance fit.
