Wheeler Engineering Delta Series Bore Guide Accessory

Wheeler Engineering’s Delta Series AR-15 Bore Guide features precision CNC-machined aluminum construction with a durable anodized finish. The guide fits securely in any AR-15 upper and can be retained by closing the dust cover, which engages a groove in the guide. For uppers without dust covers, chemical-resistant O-rings provide retention. It accommodates .223 and .204 cartridges, extending into the chamber to prevent solvent from entering the action. A solvent port positioned at the rear of the guide projects outside the upper for convenient access during cleaning. The inner tube diameter measures .250″ (not intended for 6.8mm jag).
