AP brushes — all-purpose detailing brushes — clean every part of a firearm a bore tool can't reach: trigger groups, bolt carriers, slide rails, extractor channels, and receiver corners where carbon collects. Four options cover the job: nylon for solvent-safe wipe-downs, phosphor bronze for stuck-on carbon, stainless steel for the hardest baked deposits, and a 3-piece set with all three together. Double-ended toothbrush handles give two working ends per brush, so detail work moves faster between solvent passes.
