687408648531 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.

Description:

Introducing the ultimate tool for AR enthusiasts: the JCW Wrench!

The JCW (Joint Castle nut Wrench) is a heavy-duty twin castle nut wrench, precision CNC machined from 4140 steel, heat treated, and black oxided. Designed by Forward Controls Design, this tool fulfills a long-standing need for a reliable and effective wrench.

Why Choose the JCW?

Many AR users have struggled with either cumbersome armorer’s wrenches or cheap stamped sheet metal castle nut wrenches that cannot accommodate a torque wrench. The JCW addresses these issues by combining two castle nut wrenches into one compact tool.

  • Conventional 3 Lug Design: One end features a traditional 3 lug castle nut wrench, spanning 180 degrees.
  • Unique 2 Lug Design: The other end has a specialized two lugs wrench, spaced only 90 degrees apart, making it ideal for tight spaces.

Measuring 3.5"x 1.84" at its widest point and weighing 3.14oz, the JCW is surprisingly heavy due to its robust construction. It was specifically designed to be compatible with a torque wrench, ensuring precision in your work.

Enhanced Functionality

On certain end plates with QD swivel sockets, the socket housing can obscure part of the castle nut's circumference, limiting access to the wrench notches. The FCD’s ESF (End plate, Sling adapter, Forward Controls) covers 1/4 of the castle nut's circumference, with its QD swivel housing designed to prevent bending under unforeseen pulling forces.

The JCW’s 2 lug wrench is tailored for this specific task, featuring a center socket for torque wrench use. The recommended torque for the castle nut is 38 to 42 ft/Lb, conveniently engraved on the JCW for easy reference.

Designed and manufactured in the USA, the JCW is a collaborative effort between Forward Controls Design and Arson Machine Co, OR.

Key Features:

  • Billet machined
  • Heat treated 4140 steel
  • Dedicated castle nut wrench
  • 2 lug castle nut wrench
  • 3 lug castle nut wrench

Upgrade your toolbox with the JCW Wrench – the perfect solution for all your castle nut needs!
