Montana X-Treme Bore Conditioner is specially formulated to enhance the performance of precision match-grade barrels. It is a highly refined, low residue oil created to resist the high pressures and friction that shorten barrel life and limit accuracy. Regular use after a thorough cleaning will help reduce copper fouling and protect the bore from the elements during storage. Its ultra-refined "Group Tamer" formula limits the need for first round fouling shots after cleaning, making it the ideal accuracy lubricant for hunters and law enforcement professionals.
