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 with a solid point of contact and thus eliminating any weak points in the system. The selector core is coated in black nitride, giving you a smoother surface and superior resistance to wear.

• Medium length for optimum performance
