Delta Series® Bore Guide

The Delta Series AR-10 Bore Guide is precision CNC machined aluminum with a durable anodized finish. It fits any AR-10, LR308, or 6.5 Creedmoor and can be retained in place by closing the dust cover on the upper, which engages a groove in the guide. Chemical resistant O-rings provide secure retention in uppers without dust covers. The guide extends inside the chamber to prevent solvent from leaking into the action. A solvent port is conveniently located to the rear of the guide, extending out of the upper for easy access during cleaning. By properly aligning the cleaning rod and reducing solvent overflow, the Delta Series AR-10 Bore Guide helps protect the bore and action of your rifle. Cleaning without a bore guide can allow the rod to "bow," rubbing or gouging the chamber and throat of the bore and causing real damage and loss of accuracy. Keeping the rod properly aligned not only protects your barrel, it also directs the force exerted on the cleaning rod handle, allowing tight patches to be pushed through more easily.
