Rock solid on my aero - CMMG, Inc Ambidextrous Safety Selector Kit

Awesome budget ambi safty, pretty self-explainotry. It does exactly what it needs to do for effcient handling on left and right shooters. I got this on my Aero Precesion lower for a 14.5 and the possible downside is that its pretty easy to create habits with a gun you customize. Example, getting comfortable with a BAD lever and ambi safty can get you doing some ghost movements when you pick up a standard AR with no accessories, not a deal break by any means but just something to pay attention to when you start picking up weapons from dead bodies.
