Breakthrough Clean BT17BM Bore Mop .17 Cal Cotton #5-40 Thread

The Breakthrough Clean BT17BM Bore Mop is a .17 caliber cleaning swab designed to wipe down and refresh the bore of small-caliber firearms. The mop head is made from 100% cotton, providing a soft, absorbent material that lifts residual solvent, fouling, and loose debris from the bore without scratching the rifling.

Built around a standard #5-40 thread pattern, the BT17BM threads directly onto any compatible cleaning rod or handle so you can run a wet patch or a final dry pass through the bore in seconds. The cotton mop is soft, washable, and reusable, making it a cost-effective finishing tool for routine bore maintenance and a useful companion to bore brushes in the same caliber.

A clean bore protects accuracy by preventing fouling, copper, and lead buildup that can alter a bullet's trajectory, and the Breakthrough Clean .17 caliber bore mop lays down a soft, absorbent final pass to help preserve accuracy and care for the crown and rifling between range sessions.
