The Breakthrough Brass Cleaning Jag is machined for 12 gauge shotguns from Breakthrough Clean Technologies, built to hold a patch securely as it travels through the bore (brand part no. BT-12GBJ). It uses a standard #5/16-27 thread on the jag itself and an 8/32 thread for attaching to Breakthrough Clean stainless steel cleaning rods, keeping it compatible with the rest of the brand’s rod and adapter lineup. Brass construction resists wear from repeated use without scratching the bore, and each jag is stamped with its caliber for quick identification in a cleaning kit.
