Further Product Details
This bore guide set is particularly useful for firearm owners who clean multiple rifles of varying calibers, as it eliminates the need for separate guides for each size. The included AR-15 adapter sleeve makes it suitable for modern sporting rifles in addition to traditional bolt actions. Installation is straightforward: simply insert the appropriate nozzle for your caliber, fit the guide into the action, and proceed with cleaning. The integrated solvent port allows for direct application of cleaning solutions, reducing mess and exposure to chemicals.
Routine maintenance of the bore guide is minimal—simply wipe down after use to remove solvent residue and store in a dry environment.
