Watch out make sure to the level is flush. - Odin Works Ambidextrous Modular Safety for AR-15

The Quality is nice and the FDE is perfect spot on. but the screws on the detent side seem to go in at a weird angle. did a few turns felt a bit tight tired to back off but couldn't now i'm stuck with a marred f'd up safety switch I can't use (Screw is stuck and I damaged the coating. I f'd up and it cost me 50 bucks) . moral of the story Make sure the level is flush and the screw has a few turns by finger before screwing it in with the little Allen wrench.
