Specifically designed to clean 45 Caliber pistols and sub guns. Now automatics can be cleaned correctly, from breech to muzzle, without disassembly. Panoply patches and a heavy-duty bore brush easily strip the copper from bores. Special handle with scraper, pick, and brushes clean the receiver, trigger group, and bolt. Everything is neatly packed in an 8 oz., pocket size, soft-pak case.
