Battle Arms Development BAD-ASS PRO Ambi Safety Selector – Semi-Auto (AR-15 & M&P 15-22)

Upgrade your rifle controls with the Battle Arms Development BAD-ASS PRO Ambi Safety Selector. Engineered for precision, modularity, and smooth manipulation, this premium ambidextrous selector allows you to choose between a standard 0°-90° throw or a high-speed 0°-60° short throw for faster operation under pressure.

Premium Construction & Precision Engineering

Crafted in the USA, the center core is Swiss CNC-machined from bar-stock steel, hardened, and finished in durable black phosphate for smooth engagement. The standard and short levers are made from investment-cast 8620 steel, providing maximum strength while keeping total assembly weight down to a light 0.74 oz.

Innovative Dovetail & Screw-Saving Lockup

Say goodbye to sheared lever screws. The BAD-ASS PRO features an engineered dovetail attachment and a patent-pending internal locking mechanism that absorbs operating pressure, protecting the set screws and ensuring rock-solid lever retention even under heavy tactical use.
