The Fortis SLS Fifty Ambidextrous Safety Selector in FDE (Fortis Manufacturing part no. SLS-50-FDE) replaces a standard AR-15 safety selector with a design built around Fortis’s patent-pending RidgeKey locking mechanism. Fortis Manufacturing uses RidgeKey in place of the usual socket or torx set screw, letting the levers secure onto the selector core with one solid point of contact instead of a weaker threaded joint. The selector core itself is coated in black nitride for a smoother feel and better wear resistance. Being ambidextrous, it works the same for right- or left-handed shooters without swapping parts.

Key Specifications

• A black nitride-coated selector core gives a smoother surface feel and improved wear resistance.
• Finished in FDE for a color-matched build.
• Fully ambidextrous operation works the same for right- and left-handed shooters.
