If you're tired of dealing with spacers when adjusting your length of pull (LOP), then the Kinetic Research Group Tool-less Length of Pull Kit is for you. As the name implies it allows for tool-less adjustment of your LOP and can be configured for a higher or lower buttpad position depending on your style of shooting. Length of Pull range is approximately 12" to 13.5" when installed on the 10/22 Bravo. If extra length is required, LOP Spacers and a KRG Logo Buttpad can be added to the back to reach your desired length. Fits: KRG 10/22 Bravo Chassis, Bravo Chassis for Tikka T1x and CZ-457 rimfire only Note: Not for use with centerfire rifles. Does not come with new buttpad, use your existing buttpad
