Nylon Bristle Bore Brush - .17 Caliber, #5-40 Threads Rifle

The Nylon Bristle Bore Brush - .17 Caliber, #5-40 Threads Rifle is a precision cleaning tool engineered for shooters and tactical professionals who demand reliable firearm maintenance. Whether you're running a precision rimfire platform or maintaining a .17 HMR rifle, this bore brush is purpose-built to remove powder residue, fouling, and copper deposits that accumulate during sustained fire. Proper bore cleaning extends barrel life, maintains accuracy consistency, and prevents corrosion—making this brush an essential component in any serious shooter's field kit or armory.

Constructed with durable nylon bristles, this Pro-Shot bore brush delivers effective scrubbing action without the risk of brass bristle scratching that can occur with ferrous-heavy rifling. The nylon design is gentler on modern match-grade barrels while maintaining aggressive enough bristle density to break up stubborn carbon and powder fowling. Featuring #5-40 threaded connection, the brush threads directly onto standard rifle cleaning rod adapters, ensuring secure engagement and preventing bristle loss during the cleaning stroke. The compact 5-inch overall length with 0.25-inch diameter profile allows easy access through actions and aligns perfectly with .17 caliber bore dimensions.

Law enforcement and military shooters benefit from this brush's durability during high-round-count training cycles where rapid bore fouling occurs. Hunters using .17 HMR or similar precision rimfire cartridges maintain accuracy between seasons with consistent cleaning protocols. The brush integrates seamlessly into standard rifle cleaning kits using universal rod assemblies—simply attach to your existing #5-40 threaded rod, apply bore solvent or light oil, and work the brush through multiple passes. Regular use prevents accuracy degradation and extends barrel service life, making this affordable maintenance tool an investment in firearm reliability and performance consistency.
