Pro-Shot AR-10 Bore Guide

AR Style Bore Guide with O-Ring and Solvent Port. The AR style Bore Guide with O-Ring fits in place of the bolt carrier group assembly during cleaning to center the cleaning rod and prevent damage to the chamber or muzzle. The O-Ring seal at the breech stops solvents from entering the upper receiver and trigger mechanism, effectively keeping chemicals out of the action. The Solvent Port allows for quick and easy application of CLP/Cleaner. Pro-Shot AR10 style bore guide is compatible with both 7.62mm and .308 caliber variants. Does not fit HK MR308 upper.
