I was cleaning up and organizing my garage and in particular the shooting section. While going thru some boxes I found a brand new in the package Volquartsen black bolt for MKII pistol. Wow! I had no idea I even had it or what I bought it for. I also found a brand new in the package Volquartsen Accurizing kit for MKII. The bad thing about that is I just bought one for my MKII a few weeks ago. So it pays to clean up sometimes. Pictures with the new bolt installed. Put 60 rounds through and as expected it ran perfect.
