Firearms like this deserve specialized care. Available for 5.56 mm or 7.62 mm MSR/AR style
rifles, the B.O.N.E. Tool was engineered to deliver just that. Helping you fight back debris from bolts,
bolt carriers and firing pins. Enough talk, let’s get to work. Start by taking apart your bolt carrier assembly. Put the bolt carrier scraper into the bolt
carrier and twist to scrape carbon and fouling away. Then place your bolt into the bolt scraper
and do the same thing. The finishing touch is your firing pin. It’s the same process with a different scraper. Same results, too. You expect uncompromising precision from a
firearm like this. Now, you can expect it from your cleaning
too. The B.O.N.E. Tool, only from Otis.
