I designed a drop in ambi safety selector for the 15-22 and had it 3d printed to see how well it will work. I received the prototypes today and mocked it up. It is designed to work with the
Battle Arms Development ambi safety levers. The safety selectors look fairly rough do to the low resolution of the 3d printer used. The fit is a little tight but it functions like it should.
Let me know what you think.
