Cleaning Bolt Carrier Group
Instead of scrubbing with the brush, I tried to get a tool. I got the Otis "BONE" and Real Avid Scraper Tool. Suffice to say, neither of them fit. Reading up, it seems like the M&P10 is DPMS format HOWEVER, the BCG is proprietary. What do you use to get the carbon off the bolt and dig into the carrier? TIA.
