Forward Controls Design ASF Ambidextrous Selector – Q Lever, Standard/Short

ASF (Ambidextrous Selector, Forward Controls) and SOLGW’s The Quick is a joint project between FCD and SOLGW. The two companies have been collaborating on a few projects, starting with the 4140 steel MLOK sling mount (MSQ-H in FCD alphabet soup parlance). Work began in Dec. 2018 to create a safety that’s an embodiment of their not inconsiderable experience in AR15/M16 selector design and knowledge over the years.

ASF-50 is a short-throw (rotate to 50 degrees for FIRE/SEMI) semi-auto selector with q (offset) levers.

ASF-90 is a conventional (rotate to 90 degrees for FIRE/SEMI) semi-auto selector with q (offset) levers.

ASF was designed from the ground up to be a defense/duty/combat safety selector, its mission is quite aptly reflected by the way its levers are attached to the center, via a stainless steel roll pin. The lever to the center interface is immensely strong, the high shear strength (800 lbs) 420 stainless steel spring steel roll pin simply holds the two in place, and doesn’t handle any load. One of the design goals dictates there be no wobble between the lever and center, we’ve called for very tight tolerances (+0.001/-0.00) on ASF’s lever and center interface to achieve that.

Q levers are offset levers, by shifting the lever closer to the shooter’s thumb when the selector is on SEMI/FIRE, enables the user to more easily rotate it back to SAFE without shifting his grip. For that reason, q levers are side specific, the q lever’s “leg” should always be biased towards the top. With the selector on SEMI/FIRE, the q lever should look like a letter q (hence its name).

ASF is shipped with a selector spring, a KNS nitrided selector detent, two levers, 4 roll pins (two are needed for installation, with 2 spares), with a single lever partially assembled.
