Possum Hollow Bore Guide #303
BORE GUIDES are machined from a solid piece of Delrin. This materials 100% solvent resistant. Bore Guides are designed to align the cleaning rod with the center of the rifles bore. This insures that no damage can be done to your rifle barrel, cleaning rod, or bolt face by a jag or brush.
Almost all Bore Guides, with the exception of Rimfire Bore Guides are designed with a snout that extends into the chamber. This snout has a silicone “O” ring that seals off the chamber. This insures that no solvent can run back into the action or trigger.
