Prosmith Brass Core Bronze Brush - 410 Gauge

The Prosmith Brass Core Bronze Brush – 410 Gauge by Tetra Gun Care is a precision barrel cleaning tool engineered for shooters and maintenance personnel who demand consistent, reliable fouling removal. Whether you're running a shotgun for duty, sport, or training applications, this tightly wound bronze brush cuts through carbon, powder residue, and copper fouling that degrades accuracy and reliability. Law enforcement and military armorers rely on bronze core brushes because they clean aggressively without damaging bore integrity—a critical distinction for preserving barrel life and maintaining weapon function.

This brush features a solid brass core with precisely wound bronze bristles that conform to the unique bore profile of 410-gauge shotguns, ensuring full-contact cleaning on each stroke. The 5/16-27 male thread (standard for 410-gauge and 12, 20, and 28-gauge applications) connects securely to any compatible rod with a matching female socket, eliminating wobble and ensuring centered brush action that prevents cross-hatching or uneven wear. Bronze is softer than steel, meaning it removes fouling without leaving behind metallic residue or scratch marks—a quality-of-life advantage when running high-round-count training days or post-duty cleaning cycles.

Operators maintaining 410-gauge shotguns—including those in law enforcement armories, civilian sport shooters, and serious practitioners—will find this brush essential for routine barrel maintenance and copper removal protocols. Pair it with a quality rod, appropriate solvent, and a jag or patch holder for a complete cleaning stack. This brush is compatible with standard shotgun cleaning rods featuring 5/16-27 female threads, making it a drop-in replacement for worn or damaged brushes in existing kits. One-pound weight ensures the brush handles cleanly without excessive rotational resistance during push-pull strokes.
