Connect our MDT Skeleton Rifle Stock to an MDT chassis that is equipped for a carbine stock. 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-inch, 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.
