Vortex Viper 6 MOA Red Dot

Vortex Viper 6 MOA Red Dot Sight


There is nothing better than receiving the much anticipated red dot sight in the mail and getting it installed on your firearm! The packaging is nice, and the optic comes with a nice little pamphlet, Allen/flat head wrench/screw, a cover for the optic, a cleaning cloth, and of course, the red dot optic itself! The quality was very nice right out of the box, and the sight was easy to get set up on the M&P9L Pro Series CORE.

Vortex Viper 6 MOA Red Dot

Pros: I was interested in getting a red dot optic that could co-witness with my fixed sights on my pistol, so this is why one of the major reasons chose the Vortex Viper. I had never owned a red dot sight before, and had never seen what a co-witnessed sight would look like on a pistol, but I ordered it nonetheless and couldn’t be more pleased with the outcome. I was a little concerned that maybe I would dislike the fixed sights underneath the reticle, but this really doesn’t seem to be an issue at all. The red dot is easy to fixate on without the feeling to look at the fixed sights. In addition, the controls are easy to pick up right out of the box including: adjusting the brightness of the red dot, adjusting for wind, and adjusting for elevation. There are 6 brightness settings so you can easily achieve the brightness of the red dot you’re looking for depending on the lighting level outdoors or indoors. I know that some shooters prefer a smaller red dot, but I chose the 6 MOA and it seems to be an appropriate size for my preferences.

Cons: The red dot is easy to see, no issues here, but the red dot is actually not as crisp as I would have thought a red dot sight to be. The image above is a little misleading because the camera picks it up clear and crisp, but the naked eye does not. I should note that I do have astigmatism slightly in one eye and I wear contact lenses traditionally, and maybe this could cause the issue I’m describing, but something to note nonetheless. If you’ve never used a red dot it does take some getting used to, as your eye likes to go to the fixed sights on the pistol, however with a little practice you start to look for the dot and can easily acquire your target quickly (and this really can’t be a negative against Vortex). The device comes with two locked screws that you need to loosen to adjust the wind and elevation settings, and you cannot access the lock screws without removing the red dot from the pistol. This is a little inconvenient. You also need to remove the red dot in order to replace the battery, but considering the long lasting life of the battery, this won’t be a regular inconvenience, just a once-in-a-while inconvenience. Lastly, the battery does not sit snug in place, and it takes a little bit of finagling when resetting the red dot on the firearm because the battery wants to fall out of it’s slot.

This is a very nice, reasonably priced red dot sight and what you get is nothing short of a beautiful, solid piece of equipment for your firearm. I have not taken this to the range yet, but as soon as I do I will update this review to include my experiences during live target shooting.
