Tipton Best Nylon Bore Brush 30/32 Cal 3-Pack

The 30 caliber pack covers a lot of ground: 308 Win, 30-06, 300 BLK, 7.62x39, and 32 caliber bores. Thick nylon bristles work through the carbon that piles up in a gas gun throat without putting bronze against the rifling.

Because nylon is inert in copper solvent, the brush can sit in a soaked barrel and come out ready to scrub again. The brass core is soft enough that a hard stroke will not leave a mark. The pack carries three brushes.
