Otis Bronze Bore Brush .338/.35 Cal 8-32 Thread

The Otis Bronze Bore Brush .338/.35 Cal is a precision firearm cleaning component built to scrub fouling, carbon, and copper buildup from the bores of .338 caliber and .35 caliber rifles. This single brush is sized for the .338/.35 caliber range and serves as a direct-fit consumable for shooters already running an Otis cleaning system or any standard rifle rod setup.

The brush features bronze bristles wrapped around Otis's proprietary Tufcor core wire, a corrosive-resistant construction with a tighter twist that improves bristle retention and extends brush life. The brush is cut to a 2 inch overall length and tapped with the standard 8-32 thread, so it threads directly into standard rifle cleaning rods and the slotted tips used across the Otis system. Bronze is the classic choice for scrubbing rifled steel bores, cutting residue effectively without being overly aggressive on the bore surface.

Made in the USA, this Otis brush is intended as a replacement or supplemental consumable for your cleaning kit and pairs naturally with Otis Ripcord bore snakes and slot-tipped patches for a complete pass down the barrel.
