Product Info for Battle Arms Development Full Auto Professional Ambidextrous Safety Selector

The best just got better! From the inventors of the very first fully modular, patented, ambidextrous safety selector for the AR15/M4/M16 platform, Battle Arms Development is raising the bar on reliability and compatibility while lowering the price with the new generation BAD-ASS-PRO-FA!image

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!

No more broken screws! Dont settle for wiggling levers! No more stripped screw heads! The new patent-pending dovetail design and internal locking mechanism make it impossible to shear off the screw head because there is no screw head! Do not settle for spring-loaded detents that never give your safety lever that positive lock of confidence and worry about losing the small parts. The new BAD-ASS-PRO-FA locking mechanism is robust, reliable and something you can depend your life on!
