Pro-Shot 20 GA Shotgun Jag | Solid Brass Precision Bore Tool J20

Standard cleaning often leads to "surface cleaning," where a loose patch simply glides over the mess instead of removing it. The Pro-Shot 20 GA Shotgun Jag solves this by acting like a mechanical piston, forcing the patch to conform perfectly to your barrel’s walls. By converting a passive wipe into an active scrub, this jag ensures that every inch of your 20-gauge bore—including the forcing cone—gets a deep, consistent clean that a standard loop just can't provide.

The secret to this tool is the precision-machined brass fit. Because brass is softer than your barrel’s steel but harder than carbon and plastic fouling, it creates a safe yet aggressive scrubbing interface. This tight-tolerance 20-gauge profile ensures uniform pressure distribution, which is the only way to lift the embedded residues that can eventually shift your shot consistency and internal ballistics.

Built with a solid brass body and a knurled surface, this jag grips your patch and keeps it anchored under tension throughout the entire stroke. The 5/16-27 threading provides a rock-solid connection to your cleaning rod, translating your effort into direct, linear force. It’s a specialized tool that eliminates "patch bunching" and ensures you aren't just moving dirt around, but actually restoring your bore to a mirror-bright finish.

Features

• Solid brass construction + hardness differential vs fouling and steel = effective cleaning without bore damage
• Gauge-specific diameter + tight machining tolerances = full circumferential patch contact
• Spear-tip retention design + patch anchoring under tension = zero slippage during push cycles
• 5/16-27 universal threading + rigid rod compatibility = stable, inline force transfer
