The Fortis SLS Fifty ambidextrous safety selector brings thoughtful engineering to one of the most-used controls on your AR platform rifle. Built around Fortis's patent-pending RidgeKey locking mechanism, this selector ditches the standard socket and torx screws that can loosen, break, or back out under hard use. Instead, the lever locks directly onto the selector core with a solid, engineered point of contact—eliminating the weak links that plague conventional designs.
The selector core itself is forged from 4140 steel and finished in black nitride, a coating that delivers a smoother feel and stands up to the wear that comes with thousands of cycles at the range or in the field. The ambidextrous aluminum lever design is machined from 6061 T6, keeping weight down while maintaining the rigidity you need for reliable, positive engagement. The cutout design lets you see the core underneath, making it easy to verify your safety position at a glance—a small detail that matters when seconds count.
The medium-length profile is optimized for general-purpose shooting, and the built-in lever options give you both 50-degree and 90-degree throw angles depending on your preference and hand position. Whether you're running a precision rifle, a duty carbine, or something in between, this selector adapts to your grip style and shooting technique without sacrificing reliability or ergonomics.

The Fortis SLS Fifty is designed for AR platform rifles. It's compatible with standard AR safety selector holes, though we recommend verifying compatibility with your specific rifle's lower receiver before purchase. If you're unsure, reach out to our team and we can help confirm fitment.
The selector offers both angles built-in. A 50-degree throw is faster for rapid manipulation, while a 90-degree throw provides a longer, more deliberate engagement arc. Your shooting style and hand size will dictate which angle feels more natural in your grip.
The RidgeKey system locks the lever directly onto the selector core with a solid mechanical point of contact, eliminating the fastener failure points common to conventional screw-based designs. Standard sockets and torx screws can back out, break, or snap—the RidgeKey solves that problem with no visible hardware.
