Forward Controls Design ASF-50Q Ambi Safety, 50 Degree Throw, Offset Levers
ASF-50Q is a 50-degree short-throw semi-auto selector with offset levers.
ASF (Ambidextrous Selector, Forward Controls) 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 the center, via a stainless steel roll pin. The lever to 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, 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, 4 roll pins (two are needed for installation, with 2 spares), with a single lever partially assembled.
ASF centers and levers are billet machined from 8620 steel, heat treated and coated in black nitride.
Made in the USA.

NOTE: For SR25 pattern lower receiver, the long right q (offset) lever will come in contact with the right side of the take down pin area. This doesn’t affect function.
