experimental 9mm bolt. this is a concept experimental 9mm hybrid bolt. utilizing the stripped BCG frim the DPMS c02 as the metal shell and using the "firing pin retention cylinder" in the center and is placed with the screws through it. (might have to use a differnt part) as im not to sure how well it would hold up as aluminum. however the bolt i used i foumd on here. i had to heavly modify the exterior portion and slightly internal. one would have to grind awaythe portion that protrudes slightly into the ejection port on the bottom of the bolt. the cylinder is inserted and i made click into place. as well as having 2 retention pins that will require 3 retainer pin holes to be drilled 2 of them are 1.75mm (standard metal hanger) and a 3.5mm retainer pin that captures the cylinder, boltand the metal shell together. then the 2 screws that originally used are placed back were they were with lok tight. this will require a diy firing pin however it should be fairly easy to do. let me know yalls thought and ideas.
