The Universal Bore Guide from Hoppe's keeps solvents from dripping into the action. It also helps to preserve the rifling lands closest to the chamber by preventing excessive cleaning rod contact. The aluminum action collar fits bolt actions of any length, and three interchangeable tips permit use from .17 to .416 caliber. A threaded brass pin locks the guide into the action and allows proper cleaning from the breech of the rifle.
