Not a bad safety, but i will not be purchasing it again. - ODIN Works Ambi Modular Safety for AR-15

There's absolutely nothing wrong with this safety. Very secure it it's locking in at the fire/safety position. The problem is no matter what orientation you put it in, which there are many, that it does not align in any way shape or form with the imprinted symbols on the lower. So I did say yes but I won't say no. It just depends on if you don't mind the way it lines up.
