Wheeler Engineering 156777 Delta Series AR-10 Bore Guide

The precision CNC machined aluminum, Delta Series AR-10 Bore Guide will help protect the bore and action of your rifle by properly aligning the cleaning rod and reducing solvent overflow. It fits securely in any AR-15 upper and can be retained in place by closing the dust cover on the upper which engages a groove in the guide. The bore guide also has chemical resistant O-rings for retention in uppers without dust covers. A solvent port is conveniently located to the rear of the guide which extends out of the upper making it easily accessible during cleaning.
