I have a Primary Arms MD-ADS red dot for sale. It is the model with the push buttons and not the rotary knob. It's a great sight and it's in good condition, I just don't have a use for it anymore. I do not have the box, but it will come with the lens cover. What you see in the picture is what you get. Asking $100firm. I'm not interested in any trades. Text 214-492-37zero2 anytime. Thanks.
