JCW (Joint Castle nut Wrench) is a dedicated, heavy duty twin castle nut wrench, precision CNC machined from 4140 steel, heat treated and black oxided, it's something FDC has always wanted and needed.  They couldn't find one they liked, so they answered their own prayers and made it. Like many AR users, FDC used either a heavy and unwieldy armorer’s wrench, or a cheap stamped sheet metal castle nut wench that couldn't be used with a torque wrench, both work, but neither is great.  One is overkill, the other is barely adequate. The handy JCW combines two castle nut wrenches in one.  On one end, it has a conventional 3 lug castle nut wrench, spanning 180 degrees.  On the other end, it has a unique two lugs wrench, spaced only 90 degrees apart.  JCW measures 3.5"x 1.84" (at its widest), but is surprising heavy at 3.14oz, due to its 4140 steel construction.  JCW was designed from the start to be used with a torque wrench. On some end plates with QD swivel sockets, the sockets housing masks a good portion of the castle nut's circumference, and there are occasions where not all 3 wrench notches are accessible.  FCD’s own ESF (End plate, Sling adapter, Forward Controls) covers up 1/4 of the castle nut's circumference (ESF's QD swivel housing acts as a backdrop to ensure it won't bend under unforeseen pulling force)  JCW's 2 lug wrench is designed specifically for this task. JCW has a center socket for use with a torque wrench.  TM calls for 38 to 42 ft/Lb of torque to be applied to the castle nut prior to staking in two places, this torque value is conveniently engraved on the JCW as well. JCW is proudly designed and made in the US, it is a collaboration between Forward Controls Design and Arson Machine Co, OR.    Billet machined Heat treated 4140 Dedicated castle nut wrench 2 lug castle nut wrench  3 lug castle nut wrench
