The 12 Gauge Double-Up Brush & Mop Cleaning System is a dual-action system designed for 12 gauge shotguns, combining a bore mop and a bore brush that can be screwed together for simultaneous use.
Users have the flexibility to "Double-them up" in their preferred order or add additional mops or brushes for a more comprehensive clean.
The system includes a choice of a Bronze or Nylon brush with phosphor bronze or nylon bristles respectively, and a wound cotton mop, both featuring a wound-steel shank, aluminum coupling, and a 5/16" - 27 thread for compatibility.
