Outers Shotgun Bore Brush 10/12 ga

The Outers Shotgun Bore Brush 10/12 ga is an essential maintenance tool designed for shooters and law enforcement professionals who rely on shotgun reliability in the field. Proper bore cleaning directly impacts shot pattern consistency, chamber longevity, and safe firearm operation—making this brush a non-negotiable component of any serious shotgun maintenance kit. Whether you run a Remington 870, Mossberg 500, or semi-automatic platform for duty or sport, this brush addresses fouling and copper/lead residue buildup that degrades accuracy and can lead to pressure anomalies downrange.

Sized specifically for 10 and 12 gauge bores, this Outers brush features a bronze bristle head that efficiently removes powder fouling, shot residue, and primer debris without damaging the bore wall or choke tubes. The bristles are stiff enough to break up stubborn buildup yet gentle enough for repeated use on modern hardened steel and nickel-plated chambers. At just 4.85 inches in length with a compact 1.75-inch head diameter, the brush fits easily into standard shotgun cleaning kits and rod assemblies, making it practical for both field maintenance and home bench work.

This brush delivers maximum benefit when used in conjunction with a quality cleaning rod and appropriate solvents after shooting sessions—particularly important for shooters firing shot or slugs regularly. Law enforcement armories, reserve units, and civilian shooters maintaining pump or semi-auto shotguns will find this tool indispensable for sustained barrel health and functional reliability. Compatible with standard 10 and 12 gauge shotgun bore cleaning systems, it pairs seamlessly with existing rod and handle assemblies from Outers or third-party manufacturers.
