BAD-ASS-PRO Installation



With the Battle Arms Development Reversible 90/60 Ambidextrous Safety Selector (BAD-ASS-PRO), left-handed users of the AR-15 platform no longer have to struggle with a safety selector built for right-handed users.

The BAD-ASS is machined from bar stock steel for maximum durability and a perfect fit on your AR-15 or AR-10. It features enlarged levers for positive engagement every time, even shooting under stress. The deep grooves machined into the surface of each lever prevent your fingers from slipping off. The action is smooth and finishes with an audible click upon engagement.

After the safety bar is installed, you can place your desired lever on whichever side you prefer. The levers are locked to the safety bar with the new patent-pending dovetail design and internal locking mechanism, allowing you to switch levers while the BAD-ASS-PRO is still installed on your AR-15 / AR-10.


A lot of shooters favor the conventional 90-degree operation for familiarity. But some prefer the 60-degree operation for the faster reaction time, or when using an abmi safety, the lever does not come down as far, so the opposite side lever won't rub against the hand. Shooters no longer have to settle with only one throw degree operation. The reversible 60/90-degree throw center bar gives the user the option to try or use the degree that works best.
