ASF is a short-throw semi-auto selector with standard (non-offset) levers. The ASF comes in two models, giving the end-user an option between a 50-degree rotation and a 90-degree rotation for FIRE/SEMI.
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 FCD’s not inconsiderable experience in AR15/M16 selector design and knowledge over the years.
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 little to 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. NOTE: +/- 0.002 combined tolerance (+/- 0.001 on the levers and center’s lever attachment interface) can, on rare occasions, exhibit minute movement, this is normal and unavoidable. The 0.002 of movement is almost imperceptible and doesn’t affect ASF’s function.
FCD is known to many for the dimpled pattern they use on some control surfaces (AA, or All Angles, is FCD’s designation). ASF levers are serrated, not dimpled. As the lever rotates, the user’s finger slides on the lever, anything but serrations along the length of the lever only impedes that movement and creates friction for no benefit. Serrations diagonal or perpendicular to the length of the lever are similarly unhelpful. Serrations parallel to the lever’s length help mitigate lateral movement and do not impede the finger’s sliding motion. ASF lever’s profile isn’t square, its outermost portion is somewhat tapered for a reason. When the user’s hand holds the pistol grip, the profile of the ASF lever conforms to the angle of the thumb’s pad.
For the customers that wish to see dimples on the ASF, there is a single dimple on both sides to function as a position indicator (in lieu of a pointer), it’s elegant and simple.
