Engage to fire extremely quick with the 50 degree throw on this selector.
ASF-50Q is a short throw (rotate to 50 degree 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 center interface is immensely strong, and 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. Like you expect from FCD they called for very tight tolerances (+0.001/-0.00) on ASF’s lever and center interface to achieve that. Q levers are offset levers, which is acheived by shifting the lever closer to the shooter’s thumb when the selector is on SEMI/FIRE, and it enables the user to more easily rotate it back to SAFE without shifting their 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, and 4 roll pins (two are needed for installation, with 2 spares).
ASF centers are billet machined in 8620, heat treated, and black nitrided. Levers are billet machined in 8620 and black nitrided.
