The FCD MLOK QD swivel sling adapter is not unlike other MLOK sling
adapters in the market, except MSQ-H (MLOK, Sling adapter, QD, Heavy)
is billet machined in 4140, and black nitrided. Forward Controls Design
isn't always the first to market, we only strive to be the best.
is the first of several collaborations between Forward Controls Design
and Sons of Libery Gunworks. It is based on an existing product from
Arson Machine. We deem there is no point in changing an already superb
design just so it'd look different, so we kept the design identical, and
only changed the material and coating on the MSQ-H from the original,
and added a discreet Cygnus logo.
the second product in our new line of products with the H designation
(the first being the 4140 ESF-H). Heavier than the aluminum sling
adapters, it is also stronger (4140 tensile strength is 95,000psi, vs
7075 T6 tensile strength of 73,000psi, and 6061 yield strength of
40,000), we gladly accept the trade off for better durability. We're
not known for making light weight components, our focus is ever on
duty/combat weapons grade designs where durability and practicality
trump whatever new fad the industry is embracing at the hour.
MSQ-H weighs in at 0.867oz. It's not meant to be light, it is meant to be durable.
QD swivel socket is rotation limited, MLOK mounting hardware is
included. As with all Forward Controls products, MSQ-H is proudly made
in the USA.
Recommended torque value is 35in/lbs for attaching to metal hand guards, and 15in/lbs for attaching to polymer hand guards.
An 8/32" Allen wrench (not included) is required to torque the mounting screws.
A QD swivel is not included, however they can be found: HERE
