Safety selector does not work. - Armaspec Superlight .223/5.56mm Lower Parts Kit

Bought this kit because it had a 45 degree safety. Installed it with the correct detent and spring and you cannot move the safety at all, Tried spare springs and detents just to see if that was the issue. No, it's the safety. Guessing the groves weren't machined correctly. So now I am stuck with having to spend more money to buy another safety selector after I spent more money to buy this kit. I will not be buying Armaspec again because this is the second time I've had issues with their products.
