Ambi-selctor isn't bad - DoubleStar Ambi-Safety Selector for M16

I purchased this to put on an AR pistol build. I had heard that using an M16 selector with a semi auto fire control group will give you two safety points at the 3 oclock and 9 oclock positions. This gives you a choice when training. It isn't a full 90 degree selector. It falls somewhere between 45 and 90 degrees. It is a bit gritty, but, as with some of my other selectors, I'm sure it will smooth out once it's worn in a bit. If you're looking for an M16 select fire safety, they're hard to find. As long as you don't possess the select fire control group, this is a nice addition to a build. I Think I will buy another one for my SPR build.
