Bore Tech AR-15/M-16 .223 Caliber/5.56mm Nylon Chamber Brush

The Bore Tech AR-15/M-16 .223 Caliber/5.56mm Proof-Positive Nylon Chamber Brush (brand part no. BTNC-22-100) is purpose-built to strip the stubborn carbon fouling that collects in AR-15/AR-10 chambers and barrel extensions. Bore Tech doubled the bristle count and used a double-wound, looped-end, barrel-safe core to make this brush exceptionally rigid without resorting to brass, which means it’s also the correct choice when cleaning with fast-acting copper removers that would otherwise give a false blue-patch reading.
