Montana X-Treme Cleaning Jags utilize our patent-pending barb design that ensures your patch will stay put. The barbs are arranged in opposing directions to securely grab and hold the patch when both pushing and pulling. The tip employs a radius cut from the base of the body to strengthen the tip against bending and breaking which is a common complaint with jag tips from other manufacturers. Our jags are CNC-machined to ensure exact tolerances and are constructed of solid brass for years of service.
