After more than a year of development, testing and refinement, the Battle Arms Development - Ambidextrous Safety Selector (or 'BAD-ASS') has finally been released, which is very exciting for me as a left-handed user of the AR-15. The BAD-ASS is user-configurable and addresses the issue of lever interference with the trigger hand when rotating the lever from 'safe' to 'fire'. The BAD-ASS is designed for both left and right handed shooters who believe that ambidextrous controls on a weapon are an advantage, and allow the user to operate the weapon as efficiently as possible no matter which side they're firing from.






The BAD-ASS package comes with the selector axis and three detachable levers (standard, thin and short), which are installed using torx mounting screws. A torx wrench is included in the package. The standard lever is about the same length and thickness as the standard USGI lever. It just has a different profile. To maximize 'shelf' area for the thumb to engage positively, the cross section is more rectangular than rounded/pyramidal. The thin lever is the same length as the standard lever, but half the thickness of the USGI lever. The short lever is the same thickness, but shorter than the USGI lever.







The levers have broad, angled serrations on their surface to provide a sure and positive purchase for the thumb, and also the 'crook' of the finger (when it is used to flip the lever from 'fire' to 'safe'). I find that with an ambi safety, I flip the lever from 'safe' to 'fire' with the thumb, but use the crook of my trigger finger plus the thumb to flip it back to 'safe'. There is a groove machined into the pocket of the lever, as well as the round part, which can be filled with paint for a more visible identification of lever position. I must mention that the initial inspiration for the lever shape came from a one-off custom ambi safety that my friend Shin Tanaka made for me, that I've been using for the past few years. BAD and I came up with and tested different shapes/profiles, but in the end, arrived with a profile similar to that of the Shin lever, through natural evolution and progression of the design based on testing and evaluation. A great amount of thought, time and effort went into the design of the levers from all involved.
