The bolt arrived on time and was what I needed to address a head space issue with a WMD barrel I had installed a Zero fail bolt but it what not gauge correctly with the WMD barrel it is now perfect.

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.
