Vortex Viper 6-MOA Red Dot Reflex Sight
Ratings & Reviews
Outstanding Pistol RDS
So whoever 1-star rated this sight either pays zero attention when ordering optics or doesn't understand the concept of a trade-off. This sight is substantially more low-profile than something like the RMR and the cost of that is needing reticle locking screws in the back. Does it make zeroing the optic *slightly* more work? Yes, but you only have to do that once. Rating this at 1-star over that is just ridiculous.
<br>I personally can't stand the way the RMR looks so I was looking for a suitable replacement. With Vortex's outstanding reputation and warranty program they were an obvious choice. This optic is low profile, built like a tank, has easy-to-manipulate controls, a perfectly-sized dot, and quality glass. I'm running it on a custom milled G19 slide with Heinie optic-compatible irons. You really can't go wrong with this sight.
This has locking set screws in the back. So on your handgun the rear sight is in the way blocking you from zeroing the optic. Vortex obviously isn't very bright.
