Please search your parts bins for a MW 2145 lower fourth slide assembly. They are no longer available from the factory and the next course of action is to have one made, which won't be exactly inexpensive. If one is located, please DM me here or email at chite AT buddyrogers DOT com.

Many thanks!

I believe the old M-W 2145, 2155, and 2165 all share the same piston valveset. That may expand the search in case someone has those parts
