Forward Controls Design Semi Auto Ambi 90 Degree Selector With Q Levers

The Forward Controls Design Semi Auto Ambi 90 Degree Selector With Q Levers is a purpose-built ambidextrous safety lever designed for shooters who demand precision controls and rapid manipulation under pressure. Built as a collaboration with Sons of Liberty Gunworks, this selector rotates to 90 degrees for fire/semi operation and features offset Q levers that let you keep your grip locked in while cycling the safety back to safe. Whether you're running drills at the range, working a duty rifle, or building a carbine optimized for defensive use, this selector prioritizes minimal wobble, intentional geometry, and real-world ergonomics over trendy aesthetics.

The engineering behind the ASF speaks to Forward Controls Design's combat-focused philosophy. The center body is billet machined from 8620 steel, heat treated, and finished with black nitride for durability. Levers attach via a high-strength 420 stainless steel roll pin (rated for 800 lbs shear strength) that prevents movement without bearing load. Tight tolerances—held to +0.001/-0.00 on the lever-to-center interface—result in virtually imperceptible wobble that doesn't compromise function. The design employs serrations parallel to the lever's length; they're engineered to steady your thumb's lateral movement during the rotational motion without creating drag as your finger slides across.

The Q lever's offset geometry shifts the lever closer to your thumb when the selector sits on semi/fire, letting you rotate back to safe without shifting your grip or breaking purchase on the pistol grip. The lever's tapered outer profile conforms naturally to your thumb's pad geometry. A single dimple on each side serves as a functional position indicator—simple and elegant. Levers are side-specific; the Q shape should point up when the selector is on semi/fire. The package ships with a selector spring, KNS nitrided selector detent, two levers (or one lever with end cap), and four roll pins—two for installation and two spares. Manufactured entirely in the USA.

Specifications

Frequently Asked Questions

What firearms is this selector compatible with?

The facts provided specify this is a semi-auto selector but do not list specific firearm platform compatibility. Contact Bosque Outdoors or Forward Controls Design directly to confirm fit for your build.

Are the Q levers left and right specific?

Yes. The Q levers are side-specific and offset. The lever's "Q" shape should point upward when the selector is set to semi/fire to enable proper thumb positioning and smooth manipulation without grip shift.

What's included in the box?

The selector ships with a selector spring, KNS nitrided selector detent, two levers (or one lever with an end cap), and four roll pins—two for installation and two spares for replacement or future builds.

How tight is the lever fit, and will there be any wobble?

Forward Controls Design machines the lever-to-center interface to very tight tolerances (+0.001/-0.00) to minimize wobble. Due to manufacturing tolerances, up to 0.002 inches of combined movement may occasionally be present, but this is imperceptible and does not affect the selector's function or performance.
