It works, kind of. - AT3 Tactical Ambidextrous AR15 Safety Selector

Right out of the box I was not happy with it. I ordered the grey one, the package code even had "gry" on it. It looks black. I had to be in a very bright light and put a mil-spec black one next to it to see the difference. It's there, but barely. Then there was a fitment issue with the ambi switch not seating & snugging up correctly, figured out the screw was too long for it. There also appeared to be damage/previous use to the screw from the first time I removed it to install. Perhaps from how tight the screw was from the get go. It does function as a righty safety selector, which is about the only thing going for it. It wasn't very expensive so I didn't waste my time on a return.
