This thing is awesome. I use it primarily on my range/comp gun。Overall, amazing and crisp glass, dot is sharp, and you won't lose the dot in the large window.

surprised by the quality of this little optic
I was really surprised by the quality of this little optic. I mounted it up on my Stribog 9mm, did a rough zero and took it to the range for a quick 200 rounds.<br />

Pros:<br />
* Exceptional field of view<br />
* Good optical clarity<br />
* Daylight bright<br />
* Solid body and construction
The Viper red dot’s super low mounting height makes it the perfect solution for handguns with cutout slides. Offers the simplicity and speed advantage of a red dot, while co-witnessing with suppressor-height iron sights.
