J. Dewey Brass Rifle Jag - Female Thread 12-28 .30 cal/8mm

The J. Dewey Brass Rifle Jag - Female Thread 12-28 .30 cal/8mm is a precision cleaning accessory designed for shooters and gunsmiths who demand controlled bore maintenance without risk of damage to rifling. This brass jag is engineered specifically for centerfire rifles chambered in .30 caliber or 8mm cartridges, serving as an essential component in any serious shooter's cleaning kit. Whether you're maintaining match rifles, duty weapons, or precision hunting platforms, this jag delivers the reliability and durability expected from J. Dewey Manufacturing—a brand with decades of heritage in bore care solutions.

Constructed from brass, the jag resists corrosion and eliminates the risk of metal-on-metal scoring that can occur with steel alternatives during aggressive cleaning cycles. The female thread 12-28 connection is the industry-standard interface, ensuring compatibility with any quality cleaning rod equipped with a standard 12-28 male thread. Brass composition is non-ferrous, meaning it will not magnetize or interact chemically with bore solvents and lubricants—critical for long-term rifle preservation. The precisely engineered tip design promotes even patch contact across the bore, maximizing solvent delivery and fouling removal without generating excessive friction or pressure against the rifling.

Law enforcement armorers, military personnel, and competitive shooters benefit most from this jag's precision engineering and material reliability. Installation is straightforward: screw the jag onto any cleaning rod with a standard 12-28 male thread, attach an appropriate patch, and run the rod through the bore. This product is ideal for routine maintenance, bore carbon removal, and pre-match or pre-deployment cleaning protocols. Its compact dimensions make it portable enough for field cleaning kits while providing the durability demanded by high-round-count training schedules and operational use. Pair with quality patches and proven bore solvents for optimal results.
