Breakthrough Clean BT30BJ Brass Jag .30/.308/7.62mm #8-32 Thread

The Breakthrough Clean BT30BJ Brass Jag is a precision-machined brass cleaning jag sized specifically for .30 caliber, .308 Winchester, and 7.62mm rifle bores. The caliber-specific fit holds patches snug against the bore wall, allowing solvents to cut fouling effectively and push patches through the bore without slipping off the tip.

Each BT30BJ is stamped with its caliber and cut with a standard #8-32 thread for direct attachment to Breakthrough Clean stainless steel cleaning rods. The all-brass construction is firm enough to drive patches through the bore yet soft enough to prevent damage to barrel steel and rifling. Measuring 3" in length, the BT30BJ is a compact, purpose-built tool for maintaining 30-caliber hunting rifles, precision rigs, and tactical platforms.
