Kleenbore Phosphor Bronze Bore Brush 10 ga Shotgun

The Kleenbore Phosphor Bronze Bore Brush 10 ga Shotgun (Model A187) is a precision cleaning tool engineered for serious shooters and professional operators who demand reliable firearm maintenance. Built specifically for 10-gauge shotgun barrels, this brush addresses the unique cleaning challenges posed by larger-bore shotguns, where bore diameter and residue buildup require proper mechanical action to restore accuracy and reliability.

Constructed from phosphor bronze, this brush delivers the hardness needed to remove stubborn powder fouling and lead buildup without scoring the bore. Phosphor bronze—an alloy softer than steel but significantly harder than brass—provides the ideal balance: aggressive enough to clean effectively, yet gentle enough to preserve bore integrity across multiple cleaning cycles. The brush design generates consistent contact pressure throughout the barrel, breaking loose carbon rings and copper deposits that degrade ballistic performance.

At just 0.05 lbs, the compact construction (4.95 inches overall length) integrates seamlessly into any shotgun cleaning kit without adding bulk. Law enforcement shotgun units, military personnel, and competitive shooters rely on bore brushes to maintain weapon readiness and pattern regulation between range sessions. The 10-gauge specification ensures proper fit and engagement for effective cleaning.
