Never worry about the possibility of your screw backing out, braking or snapping with the Fortis SS FIFTY™.
When designing the new Fortis SS FIFTY™, they made sure their brand’s innovation, intent and quality were evident in every aspect of the design. While most AR safety selectors in the market today rely on standard socket/torx screws, the Fortis SS FIFTY™ was engineered with their patent pending RidgeKey™ locking mechanism. This system allows the levers to secure itself onto the selector core without the use of screws. Their selector core is coated in black nitride, giving you a smoother surface and superior resistance to wear.
