Dog bone ambi safety selector - USM4 15001418 Ambidextrous Selector Dog Bone

My dog bone selector is awesome! Installed it on an Adams Arms AR-15 lower. Works as it should. I even bought another so I could have a dog bone on both sides. Very happy! --- I do want to note, I believe both selectors came in with the arms on backwards/upside down. Before installing, check the orientation of your original safety and re-install the same way. (2nd note) The other selector that I made with the circle arms is installed on a Radical Arms lower and also functions properly. Thanks OpticsPlanet!
