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!

As usual, fastest shipping in the business and lower overall cost.

Not what I needed.

I bought this for an AK, but the riser made it almost 4” above the barrel. I bought a primary arms MD-25 to replace it, but it refused to hold zero. Guess I’m not meant to use a dot on my AK.

it's OK

Excellent Red Dot

*The Good
<br>- Very fast on target
<br>- Excellent glass, very clear
<br>- Britghtness/color adjustment is simple
<br>- Looks good
<br>- Holds zero on 22LR & 5.56MM.
<br>*The Bad
<br>- Auto-off doesn't allow for you to leave the optic turned on 24/7, despite a 7,000 hour battery life on full brightness
<br>- Glare within the optic on higher brightness levels. Red is far worse than green for me
<br>I would consider buying another for a different rifle.

I own a couple of these. Really like that I can switch between red or green for the dot. Definitely awesome with the micro magnifiers! Absolutely would recommend this product!
