The 12 Gauge Double-Up Brush & Mop Cleaning System is a dual-action system designed for 12 gauge shotguns, featuring a bore mop and a bore brush that can be screwed together for one-step cleaning.
The system allows for customization, enabling users to "double-them up" in their preferred order or add additional mops or brushes for more thorough cleaning.
The kit includes one brush made of phosphor bronze or nylon and one mop made of wound cotton, both with wound-steel shanks, aluminum couplings, and a 5/16"-27 thread for compatibility.
