Wheeler Engineering Delta Series AR-10 Bore Guide

The Wheeler Enineering Delta Series AR-10 Bore Guide is made of precision CNC machined aluminum with a durable anodized finish. It fits securely in any AR10 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. It works well with .308 Winchester and NATO 7.62x51mm extending inside the chamber to prevent solvent from leaking into the action. A solvent port is conveniently located to the rear of the guide which extends out of the upper making it easily accessible during cleaning.
