The BAD-ASS-PRO series of safeties is not compatible with legacy BAD-ASS/CASS components!

The BAD-ASS-PRO has BOTH 90 and 60 degree throw options built into the reversible center


The best just got better! From the inventors of the very first fully modular, patented, ambidextrous safety selector for the AR-15 platform, Battle Arms Development is raising the bar on reliability and compatibility while lowering the price with the new generation BAD-ASS-PRO!

This professional-grade, no non-sense, duty grade semi-auto safety selector is the perfect upgrade to your AR-15. It comes standard with a reversible throw safety center with 0°-90° and 0°-60° short-throw options. The standard and short safety levers are fully interchangeable and modular to accommodate left or right-handed shooters.

The new BAD-ASS-PRO is now 100% compatible with all known(3), AR variant lower receivers, and triggers designed to work with the Mil-Spec AR-15 semi-auto safeties. No longer do you need a short-throw relief cut on your lower receiver to use the ambidextrous safety, simply use the provided short-throw markings sticker! 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 semi-auto safety, it will work with the new BAD-ASS-PRO!

No more broken screws! Don't 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 locking mechanism is robust, reliable and something you can depend your life on! The new internal locking set screw will not fall out and it is self-locking, no thread-locker is necessary! The new 5/64” set screw is also designed to resist stripping.

Battle Arms Development has perfected the ambidextrous safety with the BAD-ASS-PRO! We are so sure that you will love the new BAD-ASS-PRO, we are offering a no questions asked 30-day satisfaction guarantee (1) in addition to our limited lifetime warranty! Try it! We guarantee you will never want another ambidextrous safety ever again!

1. When purchased directly from Battle Arms Development.

2. There is no longer a "lawyer pin" like the previous BAD-ASS-ST or BAD-CASS-SA-ST short-throw safety selectors. The new BAD-ASS-PRO center will fit into all lower receivers with "Mil-Spec" safety selector hole dimensions. If the BAD-ASS-PRO safety selector is installed, on the short-throw option, in a lower receiver without the proper short-throw FIRE markings, the provided short-throw marking sticker must be used.
3. BAD-ASS-PRO safety selector is compatible with all known, to us, AR variant lower receivers and AR variant trigger designed to work with "Mil-Spec" style AR-15 semi-auto safety selectors. However, there is always a possibility that a new lower or trigger design, unknown to us, is incompatible with our safety.

    A little long, not confident in 60 degree

    Posted by Rocco on 24th Mar 2023

    The longer of the 2 selectors is longer than I would like. Short one is good. Main complaint is that you can pull on the trigger when safety is partially engaged and power through the 60 degree safety. Might switch to 90 degree throw or reach out to mfg for input.

    I've run the original Battle Arms selectors in my carbines since they hit the market. Never an issue. This new captured screw varient gives the same fit, finish and smooth operation as the original. Very pleased. The short throw option is nice as well. Especially for Larperators like me with baby hands. The price point along with quality makes it best in class. Edging out the Radian Talon in my opinion due to the steel construction.
