Keep your AR-platform rifle running reliably with the Pro-Shot .30 Cal. Military Style Nylon Chamber Brush. Designed for rifles chambered in .308 Winchester, 7.62 NATO, and .300 Blackout, this dual-purpose chamber brush effectively cleans both the chamber and the star chamber (locking lug recesses) without damaging firearm components.

The smaller forward brush reaches deep into the chamber to remove carbon, powder residue, and fouling, while the larger rear section thoroughly cleans the locking lug recesses where debris commonly accumulates. Featuring heavy-duty nylon bristles, this brush is engineered to withstand repeated use with modern gun cleaning solvents and CLP, making it an excellent choice for routine firearm maintenance.

Built with a durable brass core and reinforced wound coupling, the Pro-Shot Nylon Chamber Brush delivers long-lasting performance for tactical shooters, competitive shooters, law enforcement, and firearm enthusiasts.
