Carbon is the enemy of black guns. Firing cheap, dirty ammo accumulates carbon even faster on bolts and firing pins. The moving parts on an AR15 require a precision scraping solution, so Real Avid developed The AR15 Scraper - the first AR15 scraper designed to clean twelve critical surfaces on the bolt carrier group. Shooting is fun - cleanign isn't. The innovative double-ended swivel design saves time by remving carbon quickly and easily. It's ideal for any workbench, cleaning kit or range bag.
