Additionally, the replaceable and solvent resistant moulded rubber nosecones are soft enough to provide a superior, long-lasting seal and completely prevent cleaners from leaking into the chamber and action areas.
Designed to fit both short and long actions, these guides feature an adjustable bolt collar that firmly locks in place via the threaded brass locking handle.

How To Determine The Correct Rod Length For Your Application
Bore Guide Use Instructions For Centerfire, Bolt Action Bore Guides:
- Remove bolt as per manufacturer’s instructions.
- Loosen the brass bolt collar handle and slide the rubber nosecone (front end) of the Bore Guide through the receiver until seated in the chamber.
*Lightly push on the Bore Guide to seat rubber nosecone in chamber. - Slide the bolt collar forward until the brass handle is aligned with the bolt handle recess. Rotate the brass handle downward into the bolt handle recess and tighten against the Bore Guide tube. At this point, the guide should not move forward or backwards.
NOTE: On rifles without a bolt handle recess, it may be necessary to remove the brass locking handle and slide the bolt collar forward until the threaded locking handle hole is visible in the ejection port. Reinsert the brass locking handle and tighten it against the Bore Guide tube to properly lock Bore Guide into action. - Position a dry patch of the proper size on a jag and insert the rod/jag into the rear opening of the bore guide until visible in the solvent port.
- Apply cleaner or oil to the patch and push through the bore.
- The solvent port may also be used to apply cleaner to brushes.
- To remove the Bore Guide from the action, loosen and rotate the brass handle up and out of the bolt handle recess. Then pull Bore Guide and bolt collar back away from the chamber and out of the action.
