Excellent safety selector - Badger Ordnance Condition 1 Modular Ambidextrous AR Safety Selector

By far the best safety selector I own. You get multiple configuration options. Fit is excellent, the rotating action is smooth, and the firmness when it locks in and out of safe/fire is just right. The red arrow indicator is great too. Installation is a snap. Only need to drive in two roll pins, and you get an ample supply of spares in case you decide to reconfigure. I opted for 90 degree throw. The negative reviews seen here are probably because of out-of-spec receivers or bubbas doing bubba things. It is pricey? Yes. Is it worth it? Also yes.
