Forward Controls Design MSQ-H M-LOK QD Sling Adapter – Heavy

FCD’s 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.

MSQ-H is the first of several collaborations between FCD and Sons of Libery Gunworks. It is based on an existing product from Arson Machine. FCD deemed there is no point in changing an already superb design just so it’d look different, so they kept the design identical, and only changed the material and coating on the MSQ-H from the original, and added a discreet Cygnus logo.

MSQ-H is the second product in FCD’s 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), FCD gladly accept the trade off for better durability. Forward Controls Design focus is 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.

MSQ-H’s 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.
