Montana X-Treme Cleaning Rods are engineered to provide years of service with minimal maintenance. Only the highest quality materials are incorporated in Montana X-Treme rods. Two sets of thrust bearings secured between hardened stainless steel retainers insure an effective force is distributed during push/pull and help keep your jag or brush from unscrewing. These rods are constructed of the highest strength spring steel available and coated with our proprietary non-embedding coating. The handle is machined aluminum and sized to avoid contact with gun stocks
