In my top #2 for ambi safeties imo - Battle Arms Development Elite AR-15 Ambidextrous Safety Selector

Ive done a few builds over the past few years and ive found a couple different brands that seem to be the best out there. Radian- Talon 45/90, Battle Arms - Lite, Pro, Elite 60/90 ambi safeties. I own #2 Radians & #2 BAD: Lite & Elite. This Elite version is about as Gucci as you can get after installing the fiber optic rods and they do work. Well made and machined with a simple installation method and on off is tight and crisp. Machining is great and looks good on my Billet ADM UIC Receiver Set. The set screw that keeps dovetail latches in place works well and keeps levers tighter when compared to the Talons that do have a slight bit of play. Talons also have a spring & detent that can come flying out where these you sont have to worry about that. Fiber optic rods are .060" size and I tried TruGlo Red, Green, Orange & Green/Red colored rods. Theres a small set screw on back that locks the rods in place. The 60° throw also lines up better with my receivers pictographs better than the 45° that ends up in between symbols. Haven't got to put it through its paces yet but this is a quality product.
