A faster, easier way to clean the bolt carrier group. The AR15 Scraper removes heavy, baked-on fouling from 12 critical bolt carrier group surfaces faster and easier than brushes and solvent alone. It speed-cleans all four major parts of the bolt carrier group: the bolt, firing pin, bolt carrier, and bolt cam pin. The swivel cover protects your hand from the double ended scraping edges. It's ideal for any workbench, cleaning kit, or range bag.
