Cleaning brushes have machined aluminum components that don’t react with ammonia-based solvents like brass parts sometimes do. Won’t produce blue-green stains on your patches that can be misinterpreted as “false positive” indications of copper fouling, so you’ll know when your bore really is copper-free. Similar in hardness to brass, Copper Eliminator parts won’t scratch the bore or damage the muzzle, and they’ll stand up to hard use. Nylon bristles wound around an aluminum core and male-threaded aluminum coupling are completely brass-free to eliminate false-positive blue-green indications of copper fouling that can occur when using ammonia-based solvents with brass core brushes. Dense nylon bristles give plenty of scrubbing power, yet are extremely gentle on the rifling. .17 and .20 caliber brushes with 5-40 threads extend the benefits of the Copper Eliminator system to your existing small-caliber rod. The .22 caliber and larger brushes have 8-32 threads for use with Dewey Copper Eliminator rods.

Brownells USA Not a good quality 11/02/2014

Bought these brushes to clean my AK-47. All three from the pack broke apart at the 1st or 2nd use. Very dissapointing. Although .223 brushes of the same type work just fine on my AR15.
