Forward Controls Design Semi Auto Ambi 90 Degree Selector With Q Levers
Forward Controls Design
The Forward Controls Design Semi Auto Ambi 50 Degree Selector with Q Levers is a purpose-built safety lever for AR-platform rifles designed with the working shooter in mind. Born from a collaboration between Forward Controls Design and Sons of Liberty Gunworks, the ASF-50Q brings a combat-tested approach to ambidextrous safety selection—rotating just 50 degrees between FIRE and SAFE for fast, intuitive thumb transitions under stress. This isn't a universal safety; it's engineered for shooters who demand speed and reliability from every control surface.
The Q lever offset design is the key difference here. By positioning the lever closer to your thumb when the selector is on SEMI or FIRE, you can rotate back to SAFE without breaking your firing grip or shifting your hand. The levers are side-specific (the offset "leg" biases toward the top), and they're serrated along their length—not dimpled—because serrations parallel to the lever direction actually aid finger movement without creating unwanted friction. A single dimple on each side serves as a position indicator, keeping the design clean and functional. The selector center is billet machined from 8620 steel, heat treated, and black nitrided for durability; the levers get the same treatment. Tolerances are held tight to eliminate any wobble between lever and center, and the interface is pinned with a high-shear-strength stainless steel roll pin that won't deflect under hard use.
Installation is straightforward. Your package includes the selector spring, a KNS nitrided selector detent, two complete levers (or one lever with an end cap for right- or left-hand operation), and four roll pins—two for installation and two spares. Made in the USA by a builder known for uncompromising control design, the ASF-50Q is built for duty, defense, and serious shooting where your safety mechanism needs to work exactly as intended, every single time.

The Q lever offset moves the lever closer to your thumb when on SEMI or FIRE, allowing you to reach SAFE without adjusting your grip. Combined with the 50-degree throw and tight tolerances designed to eliminate wobble, the ASF-50Q is purpose-built for fast, positive control in defensive or duty scenarios. The serration pattern is optimized for finger travel, not aesthetics, and the design philosophy prioritizes function under stress.
Yes, Q levers are side-specific because the offset "leg" must bias toward the top. When the selector is on SEMI or FIRE, the lever should resemble the letter Q. The package includes two complete levers (or one lever and an end cap), allowing you to set up the selector for either right- or left-hand operation, but you should not swap the levers between sides.
Your ASF-50Q comes with the selector spring, a KNS nitrided selector detent, two levers (or one lever with an end cap), and four roll pins—two for installation and two spares. You'll need basic tools to remove your current selector and install this one, but no additional parts are required for a standard AR-platform upper receiver.
The ASF-50Q is designed for AR-platform rifles with standard receiver selector holes. This is a semi-auto safety selector (rotating to 50 degrees for the FIRE position), so it is only compatible with semi-automatic rifles. Verify that your upper receiver uses a standard selector boss before ordering.
