The Forward Controls Design (and SOLGW) ASF-90 is a conventional semi-auto selector, rotating 90 degrees from Safe to Fire, featuring standard (non-offset) levers. Designed from the ground up for defense, duty, and combat, the ASF boasts robust construction. Its levers are attached to the center via a stainless steel roll pin, providing an immensely strong lever-to-center interface. The 420 stainless steel spring steel roll pin, with a high shear strength of 800 lbs, securely holds the components in place without bearing any load. The ASF package includes a selector spring, a KNS nitride selector detent, two levers (or one lever with an end cap), and four roll pins (two for installation and two spares). One lever comes partially assembled. The end cap allows users to convert the selector between ambidextrous and non-ambidextrous configurations, catering to those who prefer not to have a lever on the weak side of the receiver.
