Battle Arms BAD-ASS-PRO Full-Auto Ambidextrous Safety Selector

BAD-ASS-PRO-FA Full-Auto Ambidextrous Safety Selector

The BAD-ASS-PRO-FA from Battle Arms Development is a premium, duty-grade ambidextrous safety selector engineered for a confident, positive feel and long-term reliability. Built around a Swiss CNC machined, hardened bar-stock steel core and paired with rugged 8620 steel levers, it delivers smooth operation with a modular design that adapts to your preference.

The standout feature is the dovetail attachment and internal locking mechanism—designed to eliminate common issues like stripped heads and broken screws, while keeping lever engagement solid and repeatable. This professional-grade, no non-sense, duty grade semi-auto safety selector is the perfect upgrade to your AR-15/M4/M16 Machine-gun. The standard and short safety levers are fully interchangeable and modular to accommodate left or right-handed shooters.

The new BAD-ASS-PRO-FA is now 100% compatible with all known(2), AR variant lower receivers, and triggers designed to work with the “Mil-Spec” AR-15/M4/M16 full-auto safeties. No longer do you have to choose which trigger is compatible with the safety! If the trigger it will work with a “Mil-Spec” AR-15/M4/M16 full-auto safety, it will work with the new BAD-ASS-PRO-FA!
