B/C Nylon Bore Brush .270/6.8Mm Red

A Birchwood Casey nylon bore brush in .270/6.8mm is a workhorse cleaning tool for rifle maintenance. Unlike brass alternatives that can leave marks on softer barrel steel, this brush uses red nylon bristles to scrub fouling—copper, lead, carbon, and plastic wad material—without risk of damage. The dense bristles apply real scrubbing force where you need it, flexing to reach the rifling and then snapping back to shape, so the brush holds up through dozens of cleaning cycles without matting or splaying.

Built for hunters, long-range shooters, and anyone who maintains their own rifles, this bore brush fits standard .270 and 6.8mm caliber rifles. Drop it on a cleaning rod, add some bore solvent, and work it back and forth—the multi-directional bristle design lifts stubborn deposits that a patch alone won't touch. The rigidity of the nylon means you get aggressive cleaning without the worry of scoring a barrel that cost far more than the brush.

Whether you're breaking in a new rifle, deep-cleaning after a long range session, or doing regular maintenance, a quality bore brush is non-negotiable. This Birchwood Casey brush delivers the durability and cleaning power that working shooters expect, at a price that makes sense to keep a spare in your cleaning kit.

Specifications

Frequently Asked Questions

What calibers does this bore brush fit?

This brush is sized for .270 and 6.8mm rifles. Always match your brush diameter to your bore to avoid reduced contact and cleaning efficiency.

Will nylon bristles damage my barrel?

No. Nylon is significantly softer than steel and will not score or mark barrel steel. Many shooters prefer nylon for this reason, especially on precision rifle barrels where any damage is a concern.

How do I use this brush?

Thread it onto a cleaning rod, apply bore solvent to the bristles, and work the brush back and forth through the bore with firm pressure. The bristles flex into the rifling to lift fouling. Clean from breach to muzzle whenever possible to prevent debris from exiting near the muzzle crown.

How long will this brush last?

Nylon bristles are durable and return to their original shape after each use. With normal care, this brush will last through many cleaning cycles, making it a lasting part of your maintenance toolkit.
