ade from LimbSaver’s proprietary NAVCOM technology (Noise and Vibration Control Material), the Sharpshooter X-Ring tunes the vibration waves that affect shot grouping. Each of these individual waves negatively affects the barrel and the Sharpshooter X-Ring is specifically designed to control them. By reducing this energy and tuning the dampening characteristics to a specific location on the barrel, you can consistently control muzzle movement during lock-up time, which translates to greater accuracy.
