Possum Hollow Bore Guide #145 - .270 Win, 7MM-08 Rem, 308 Win Fits Heym SR21
Using a Possum Hollow Bore Guide is the easiest and safest way to preserve the accuracy of your bolt action rifle and to clean your rifle from the rifle's chamber end using a Bore Guide. Possum Hollow Bore Guides protect the chamber and bore of your rifle by guiding the cleaning rod through the barrel. An O-ring seal prevents solvents or oils from seeping into the action and trigger mechanism.
For optimum performance, add an optional solvent port (sold separately). Solvent Ports fit into the end of the Bore Guide to ease solvent application and end messy spills.
