My friend put a Timney Calvin Elite in his competition AR and he’s getting unintentional autofire doubles when he free recoils. This trigger is not adjustable iirc. He can’t afford a different trigger right now, so I’m thinking it’s Xmas present time. I think he wants a non adjustable trigger, and he wants to be able to shoot free recoil without getting a double. But he doesn’t want a stiff (e.g., milspec) trigger. Any suggestions?
