Birchwood Casey 41285 MSR Chamber Brush 7.62/.308 Bronze/Steel

The Birchwood Casey 41285 MSR Chamber Brush delivers thorough cleaning for 7.62/.308 chambers where standard brushes fall short. This specialized tool removes stubborn carbon buildup and fouling that accumulates in the chamber area of modern sporting rifles.

What Makes This Different

Unlike standard bore brushes, this chamber-specific brush features a dual-material construction with bronze bristles and steel core designed to match the chamber dimensions of 7.62/.308 caliber rifles. The brush head geometry conforms to chamber contours, reaching areas that straight-through cleaning rods cannot access effectively. Standard cleaning methods often leave residue in the chamber throat and shoulder areas where this brush excels.

Key Features

• Precision-sized for 7.62/.308 NATO and .308 Winchester chambers
• Bronze bristles provide effective cleaning without damaging chamber surfaces
• Steel core construction maintains brush shape under pressure
• MSR (Modern Sporting Rifle) specific design for AR-10 and similar platforms
• Compatible with standard cleaning rod threads
• Removes carbon fouling from chamber throat and shoulder areas
• Durable construction withstands repeated use and cleaning solvents

This chamber brush proves essential for maintaining accuracy and reliability in high-volume shooting scenarios. Competitive shooters and tactical users report improved extraction reliability after thorough chamber cleaning. The brush effectively removes the baked-on carbon deposits that can cause extraction failures and accuracy degradation. Regular use prevents the accumulation of fouling that leads to sticky bolt operation and inconsistent chambering.
