The MDT LSS GEN3 XTN Buttstock Interface in black (brand part no. 110085-BLK) is the piece that joins a buttstock to the back of an LSS GEN3 chassis base. The LSS GEN3 chassis was built to be modular, and that includes the back end, so you can swap interfaces in minutes. Changing the interface does not require pulling the barreled action, which means no re-zeroing. MDT machines the interface from 6061 aluminum and finishes it in Cerakote. It is made for a shooter who wants to switch from a compact truck gun to a long range setup, or simply try a different feel.
