Real-World Testing: Putting CMMG Mkgs .40 S&W Bolt Maintenance Kit to the Test

First Use Experience

I put the CMMG Mkgs .40 S&W Bolt Maintenance Kit to the test during a scheduled deep cleaning and inspection of my MkG. The testing grounds were my well-equipped home workshop, providing ample space and tools. The focus was on ease of installation and whether the replacement parts matched the quality and dimensions of the originals.
