Gerald's Review of Maxim Defense Industries Universal 9mm Bolt Carrier Group (BCG) w/Weight Plug

I had failure to fire after about 300 rounds using rhis bcg. After pulling apart the bolt carrier group, i found the firing pin spring had compressed and broken off towards the end.
Ordering a new spring and will see how it goes
