Why Choose a Nylon Bore Brush for .30/.308/7.62?
Non-marring performance: Nylon is gentle on rifling and crowns, making it ideal for carbon steel, stainless, and chrome-lined barrels.
Solvent-ready bristles: Chemical-resistant nylon stands up to aggressive carbon cutters and copper solvents for deep cleaning when you need it.
Full-contact scrub: Dense bristle pack with an evenly wound core maintains uniform, 360° pressure so fouling lifts quickly and evenly.
Durable & dependable: Resists deformation over multiple passes and high round counts—ideal for frequent shooters and armorers.
Retail packaged: Sealed presentation protects bristles from dust and shop debris between uses.
Optimized for Popular .30 Caliber Platforms
Perfect for .308 Win, 7.62×51 NATO, .30-06 Springfield, .300 BLK, .300 Win Mag, and other .30-caliber rifles and pistols that use a .30/7.62 cleaning rod system. Whether you shoot precision bolt guns, gas guns, or hunting rifles, this nylon brush helps maintain accuracy and reliability.

Faster, Cleaner Results
Nylon filaments flex into micro-crevices and machining marks to lift fouling while protecting your bore. Pair with your preferred solvent, let chemistry work for a short dwell time, then brush in smooth, full-length strokes. Follow with dry patches and a lightly oiled patch for a bright, uniform finish that resists corrosion.
How to Use (Best Practices)
Unload & verify safe. Always check chamber and magazine.
Pre-wet the bore. Apply solvent with a patch or mop; allow a brief dwell to soften deposits.
Brush breech to muzzle. Make full-length strokes with the nylon brush; avoid reversing direction mid-bore.
Repeat as needed. Nylon tolerates strong solvents—reapply as necessary for heavy fouling.
Patch and protect. Run dry patches until clean, then finish with a light oil pass.
Pro Tip: Keep two brushes on hand—one dedicated to solvent work and the other for quick touch-ups. Rotating brushes preserves stiffness and extends service life.

Care & Maintenance
