Keep your AR-15 and other modern sporting rifles clean and ready for action with the Otis® MSR Cleaning Pack. This inclusive kit features a durable bronze chamber brush, designed to reach deep into lands and grooves for a thorough clean you can depend on. The Ripcord® bore cleaning rope features a rigid, helix-shaped rubber core for a reliable Breech-to-Muzzle® clean, while the braided Nomex® surface easily withstands temperatures of up to 700°, allowing you to clean your firearms while the barrel’s still hot. The B.O.N.E.® Tool is specifically designed to remove carbon fouling from the bolt, bolt carrier, and firing pin of an AR-15 for smooth, reliable operation. The star chamber tool quickly removes carbon buildup, while the brass nose piece centers the tool in the chamber for proper cleaning and protects the firearm from scratches and damage. What’s more, this kit includes an all-purpose brush, designed to scrub away carbon and other fouling from most firearm surfaces. Made in USA.
