Still not fully sure about it - Phase 5 Weapon Systems Inc Ambi Safety Selector 90 Degree

The only thing I don’t like is that on my billet lower from joe bob outfitters, the safety selector is on too tight it won’t move, I unscrew and tiny tiny bit and it will move now but the selector itself is now a little wobbly. I don’t know if it’s my billet lower that is causing for the selector to be too tight it won’t move or I received a defective selector. Or that’s just the way it is. Will try on two different lowers and see if it makes a difference.
