Product Description
The barrel spacer and nubs contained in this pack allow you to use a stock or upgraded KC-02 barrel with your VSR chamber. Useful if you want to use VSR buckings but already have an upgraded KC-02 barrel you like. Buckings with extended contact points (like the Maple Leaf) will not work with KC-02 barrels as the barrel's hop window cut is too short.
