Machined Delrin® guide lets you safely clean your .30-06/.308 bolt action rifle from the breach—the proper way—by protecting the chamber and rifling from damage by the cleaning rod. Just remove the bolt assembly and insert the guide in its place to keep solvent from dripping into the action or trigger assembly. Silicone rubber "O" ring keeps the guide centered in the chamber for a snug fit and prevents solvent leakage. Integral port machined into the rear of the guide lets you put solvent on the brush or patch without spilling it on your work area.
