Wheeler Engineering 156213 Delta Series AR-15 Bore Guide

The Wheeler Enineering Delta Series AR-15 Bore Guide is made of precision CNC machined aluminum with a durable anodized finish. It fits securely in any AR15 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 .223 Remington .204 Ruger and NATO 5.56x45mm 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.
