Pro-Shot 20C 20 Gauge Shotgun Chamber Brush - #5/16-27 Threads

The Pro-Shot 20C is a dedicated 20 gauge shotgun chamber brush built to clear stubborn plastic wad, fouling, and debris from shotgun chambers quickly and thoroughly. Regular use of a chamber brush helps prevent misfires, stiff extraction, and cycling issues caused by buildup in the chamber area - particularly important for high-volume shooters running semi-auto shotguns.

This brush is built around a brass core with quality bristles sized for the 20 gauge chamber, and it threads onto any standard shotgun cleaning rod using American Standard #5/16-27 shotgun threads - the common thread pattern for 20 gauge shotgun cleaning tools. It pairs directly with the Pro-Shot PXCH20 chamber cleaning handle for a complete chamber-cleaning setup, or works as a stand-alone attachment on your existing rod.

The 20C is made in the USA by Pro-Shot Products and is packaged in a reusable storage tube to keep the bristles protected and straight between cleanings. Whether you are maintaining a 20 gauge semi-auto for clay season, a tactical 20 gauge pump, or a vintage side-by-side, this chamber brush is a simple, effective addition to any shotgun cleaning kit.
