Forward Controls Design ASF-90 Ambi Safety, 90 Degree Throw, Standard Levers ASF-90 is a 90-degree throw semi-auto selector with standard 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. 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.
