The MSQ-H MLOK QD swivel sling adapter is not unlike other MLOK sling adapters in the market. The MSQ-H (MLOK, Sling adapter, QD, Heavy) is billet machined in 4140, and black nitrided.
MSQ-H 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.Keeping the design identical, and only changing the material and coating on the MSQ-H from the original, while adding a discreet Cygnus logo.
MSQ-H is the second product 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. FCD is not known for making light weight components, their 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.
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.
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.
