Allens revolutionary BORE-NADO barrel cleaning rope makes taking care of your firearm easy. Simply add solvent of your choice to the cleaning rope and clean from breach to muzzle in a single stroke, repeating as necessary until clean.

The vortex bristle technology uses copper brushes to blast fouling and debris as it passes through your barrel, and the built-in braided swab sweeps it away. Keep in your range bag or gun case for quick clean-up jobs. Can also be incorporated into your full cleaning routine if you aren t a fan of handing all the interchangeable parts of other cleaning systems.
