Vortex red/ green dot review


It's a very good product for the price. It ships right away and it arrived on time.

Customer Service


Primary Arms has been excellent to deal with. Most products are in stock and the shipping is very fast and affordable. This optic is also fantastic for the price. I have been running the Vortex for 2 years now without a flaw.

Great service and product


The vortex is awesome. Just what I needed for my ar 15. Customer service is great. Sent a email and it was responded to very fast. Thanks again.

I own two, maybe three soon. Love these sights.

Love it


Just got my 3rd Strikefire today and as usual shipping was crazy fast and the optic is as good as advertised. It’s been a few years since I got the first one and it still works like a champ.

Great deal, fast shipping!
