Our 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.
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. 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.
MSQ-H is 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.
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.

Great QD mount. Very positive retention and slim design

Most QD sling cups are made of aluminum—including those machined into most handguards. When a steel fitting meets an aluminum socket, the result will inevitably be wear which will cause the connection to fail at some point. The MSQ-H is heavy (I think that’s what the H stands for) but solid; it will not wear out the way an aluminum connector will. The design is otherwise simple, straight-forward, and works… there’s not a whole lot to say about it. Rooftop was lightning fast in sending it out, as always.

Stocking up on various small parts so I can fix my own stuff. This was part of a big order of that and it all came flawlessly. As always, the sweatshop delivered lightning fast. Eat the ramen or you’ll go to hell.

The best QD adapter on the market. Slim design decreases the likelihood of it becoming a snag hazard and lock up is very secure.
