Battle Arms Development Bad-Ass Ambidextrous Safety Selector Short Throw Standard Short Black

Buyer Beware..

Very awesome ambi selector, reminiscent of the SCAR, works very well. However, be aware that this selector is designed to work with a specific lower receiver, not just any lower. There's a little steel post welded to the selector that will prevent you from inserting it into a regular lower. It's possible to file it off, but that voids the warranty. Still a wonderful selector, though, very positive, very natural. If I build any more ARs, I'll probably buy this again.
