Designed to dampen out unwanted vibration by shortening the overall settling of the barrel. Accuracy benefit is immediate, providing sub-minute angle groups with over-the-counter factory ammunition. Easy to install. Manufactured with LimbSaver's proprietary NAVCOM® (Noise and Vibration Control Material) for maximum performance and accuracy. Color: Black.
Made in USA.
Never tried one thinking about it - though... Wonder if it will even fit a ML barrel?
