The Carbine to Fixed Stock Adapter installs in seconds and increased the modularity of our MDT rifle Chassis. Will increase the LOP (Length of Pull) by 0.75", if LOP becomes an issue consider the short version of our Skeleton Rifle Stock. Can also be used on the Savage Stealth which is a chassis developed on an MDT platform.
