Forward Controls Design Duplex 2 & 3 Lug Wrench with Wrench Socket, Black

The Forward Controls Design Duplex 2 & 3 Lug Wrench with Wrench Socket, Black (brand part no. JCW, Joint Castle Nut Wrench) is a buttstock castle nut tool built by Forward Controls Design to fit both common 2-lug and 3-lug castle nut patterns in one wrench. Having both patterns covered in a single tool means a gunsmith or home builder doesn’t need to stock two separate wrenches for different receiver extension setups. The included socket adds torque leverage for breaking a stubborn castle nut free or seating one to spec. It’s finished in black to match the rest of a dark range or gunsmithing tool set.
