Wheeler Delta AR-10 Bore Guide

Wheeler Delta AR-10 Bore Guide. Cleaning without a bore guide can allow the rod to ?bow? and rub or gouge chamber and throat of the bore causing real damage and loss of accuracy. Keeping the rod properly aligned not only protects your barrel it directs the force exerted on the cleaning rod handle allowing tight patches to be pushed more easily. The AR-10 Bore Guide is precision CNC machined aluminum with a durable anodized finish. It fits securely in any AR-15 upper and can be retained in place
