JMW is the newest addition to the Forward Controls Design line of dedicated, high quality
AR15/M16 tools. It is a combination wrench with a 3/4 wrench with a
0.23 thickness for the A2 compensator, and another 3/4 wrench with a
0.20 thickness for the Keymo, Key Micro mounts, such as our 6315KM,
6310KM, SOLGW's NOX, and Dead Air's flash suppressors, compensators and
brakes. The 0.20 side is also suitable for use with other suppressor
mounts that have thinner than A2 spec (0.23) flats.
follows the well developed JCW (Joint Castle nut Wrench) form factor,
it is a compact wrench designed to be used with a torque wrench (1/2
Most armorer's wrenches have a
rather thick 3/4 wrench for torquing the A2 compensator. While adequate
for the A2 compensator, this presents an issue with muzzle devices with
thinner than A2 spec flats, an armorer wrench's 3/4 wrench often can't
find enough clearance, and is too thick for the flats which are
sandwiched between the barrel and the muzzle device's sound suppressor
mounting interface. To make things more complicated, some muzzle
alignment shims can be of slightly larger outer diameter than the
barrel. A typical 3/4" wrench often can't be used to torque these
JMW's thinner side of the 3/4"
wrench has a thickness (0.20) designed for muzzle devices with thinner
than A2 compensator spec flats, such as Dead Air's Keymo, Key Micro
suppressor mounts, and Surefire suppressor mounts. Billet machined in
4140, heat treated and black oxided, it has the recommended torque value
(20 to 30 ft/lb) laser engraved.
JMW is another joint project between Arson Machines and Forward Controls Design. Proudly designed and made in the USA.
