- Tapered bronze bristles scrub the chamber, neck, and shoulder with aggressive cleaning action
- Steel bristles at the base target the star chamber and locking lug recesses where carbon and fouling accumulate
- Cold-welded brass stem provides durability and reliability
- Folded tip design (not cut) ensures longevity and consistent performance
Specifications

- Thread Size: 8-32 (standard for most rifle cleaning rods)

Why It Matters
The chamber is where the most severe fouling occurs in a rifle. Proper chamber cleaning extends barrel life and ensures reliable feeding and extraction. The dual-bristle design addresses both the primary chamber surfaces and the critical locking lug recesses that many shooters overlook. This brush is an essential component of any serious rifle maintenance routine.
