Bore Tech .375 Caliber Nylon Rifle Bore Brush, 3-Pack

The Bore Tech .375 Caliber Proof-Positive Nylon Rifle Bore Brush (brand part no. BTNR-375-03) is built for shooters who rely on fast-acting copper-removing cleaners and don’t want a bronze brush giving a false blue-patch reading. Bore Tech engineered these with twice the bristle density of a standard nylon brush and a non-brass core, so they scrub harder without reacting to copper solvents like Eliminator or Cu+2. Sold three to a pack in .375 caliber, this brush is the one to reach for whenever a copper-fouled rifle barrel needs real scrubbing action instead of a token pass.

Key Specifications

• Sized for .375 Caliber bores, matching the caliber marked on the brush core.
• Built with oversized nylon bristles, twice the density of a standard nylon brush.
• Features a non-brass core that won’t cause false blue-patch copper readings with copper-removing cleaners.
• Threaded 8/32 to fit standard cleaning rod handles.
• The looped-end core eliminates the sharp cut ends found on lower-quality bore brushes.
• Sold as a 3-pack, giving a spare on hand before the first brush wears out.

Frequently Asked Questions

Why use a nylon brush instead of bronze? Bronze brushes are over 90% copper and turn patches blue with copper-removing solvents, giving a false fouling reading; this nylon brush won’t.

Is it safe to use with Bore Tech’s copper removers? Yes, that’s exactly what it’s designed for. The non-brass core and threads are unaffected by Eliminator or Cu+2 Copper Remover.

How many brushes come in the pack? Three brushes per pack, so a spare is always on hand once the bristles wear down.
