The KleenBore 12 Gauge/20 Gauge Combo Classic Cleaning Kit (SHO12/20) is a dedicated shotgun maintenance system designed for routine cleaning, fouling removal, and corrosion protection. Built around a 3-piece large-diameter aluminum cleaning rod with an assembled reach of 32 inches (approx. 81.3 cm), the kit provides direct maintenance coverage for the two most common shotgun gauges without requiring separate tool purchases. It features dedicated phosphor bronze bore brushes that scrub out leading and plastic wad residue without scratching steel or chrome-lined bores, alongside Mil-Spec Break-Free CLP to clean, lubricate, and protect internal mechanisms.

Who is the KleenBore 12 Gauge/20 Gauge Combo Classic Cleaning Kit for?

  • Clay target and trap shooters — Needs a dual-gauge shotgun cleaning kit with a 32-inch assembled aluminum rod to efficiently clean plastic wad buildup and powder fouling from 12-gauge and 20-gauge competition barrels.
  • Waterfowlers and field hunters — Relies on the included 0.5 oz dropper bottle of Mil-Spec Break-Free CLP alongside a rigid #5/16-27 threaded rod to strip field grime and apply corrosion protection to hunting shotguns exposed to wet environments.

Less suitable for: Shotguns with barrels exceeding 32 inches when cleaned from the chamber with the action attached (which require a rod extension), non-standard sub-gauges like .410 out-of-the-box (which require separate brush and jag purchases), or rifles and handguns requiring smaller-diameter rods with #8-32 or #5-40 threading (which require a dedicated caliber-specific rifle/pistol cleaning kit).
