I ran across this in a recent NRA American Rifleman issue. Apparently, Battle Arms Development (yes.... BAD) has developed a new safety selector for the AR (15 and 10). The BAD Ambidextrous Safety Selector (ASS, yes.... BADASS - no joke here). It appears that the BADASS can be installed in an ambi or non-ambi config using torx screws on either side of the safety. The lever(s) have smooth edges with diagonal grooves on the sides for grip and comes with a stainless detent for install.

From the BAD order page: Semi-Auto Ambidextrous Safety Selector for the AR15 / AR10. Both levers are detachable and interchangeable for maximum flexibility and user preference. Package comes with:

* (1) SAFETY BAR/AXIS
* (1) STANDARD LEVER
* (1) SHORT LEVER
* (1) THIN LEVER
* (2) TORX SCREWS
* (1) HARDENED STAINLESS STEEL SAFETY DETENT (by KNS Precision)
* (1) T10 TORX L-Key
* Precision CNC Machined from Solid Bar Stock Steel!
* MADE IN U.S.A.
* PATENT PENDING


Anyone have any experience with one of these?
