Breakthrough Clean Bore Mop 20 Gauge 3.5" Cotton #8-32 Thread

The Breakthrough Clean Bore Mop in 20 gauge is a soft, washable 100% cotton cleaning swab designed to scrub fouling, lead, and powder residue from shotgun bores without harming the bore's finish. The fluffy cotton mop tip delivers effective scrubbing action on caked-on fouling while remaining safe on bore surfaces, making it a go-to swab for routine post-range and end-of-season shotgun cleaning.

At 3.5" long and cut to fit a 20 gauge bore, this mop threads onto any standard cleaning rod with a #8-32 thread pattern for quick attachment and easy swap-out between cleaning steps. Because the cotton tip is fully washable and reusable, a single mop can be deployed across many cleaning sessions. Pair it with a quality bore solvent and a good rod for fast, thorough shotgun bore cleaning. One mop per package.
