Forward Controls Design SF-50 Ambidextrous AR Safety Selector Black

Forward Controls Design SF-50 Ambidextrous AR Safety Selector Black. 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 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 little to no wobble between the lever and center weve 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 can exhibit minute movement this is normal and unavoidable the 0.002 of movement is almost imperceptible and doesn't affect ASF's function. Forward Controls Design is known to many for the dimpled pattern we use on some control surfaces (AA or All Angles is our designation). ASF levers are serrated not dimpled. As the lever rotates the users 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 outer most portion is somewhat tapered for a reason. When the users hand holds the pistol grip the profile of the ASF lever conforms to angle of the thumb's pad. For the friends and 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) its elegant and simple. ASF centers are billet machined in 8620 heat treated and black nitrided. Levers are billet machined in 8620 and black nitrided. ASF is a collaboration with Sons of Liberty Gunworks.
