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. Standard 8 x 32 thread (.17 and .20 Cal jags
have a 5 x 40 thread, and shotgun jags have a 5/16 x 27 thread). .17 Cal.
