The AR style Bore Guide slides in place of the bolt carrier group assembly while cleaning. This centers the cleaning rod while preventing solvent from entering the upper receiver and trigger mechanism. The AR10 style bore guide can be used for all of the AR10/LR-308 family of rifles. Pro-Shot's bore guides are manufactured using Delrin. Delrin is chemical resistant and will stand up to harsh chemicals, providing continual use.

Material: Aluminum/Delrin
