Viper Red Dot - 6 MOA Dot (VRD-6)

The Viper Red Dot's super-low mounting height makes it the perfect solution when there are no cutout slides. The Viper gives the simplicity and speed advantage of a dot sight, while co-witnessing with iron sights. The trade off? Nothing. The 6 MOA dot diameter gets on target fast.

Fully multi-coated, ultra-clear lens offers a wide, unobstructed field of view. The left-side up/down power and illumination controls are easy to access and manipulate. Recessed 1 MOA windage and elevation adjustments are super clean, protected from incidental contact, and always at the ready. It runs on a CR 2032 battery. The Viper comes with a Picatinny mount-weighs 2.1 ounces with mount.

Awesome for Glock MOS
Excellent optic for pistol, especially Glock MOS.MOS SCREWS:Mine came with the screws for the Glock MOS. After reading other reviews that said to call and ask for them, I did, only to find out that once I received the MOS screws, they had already been included. They were not labeled in the original package, so I included a picture so that you can identify the MOS screws in case they are in your package (the screw on the penny is the MOS screw).MOS INSTALLATION:I read other reviews on various sites that discussed the need for a shim or gasket from UM Tactical and also filing down the tabs on the MOS plate number 1. Neither of these are necessary. Perhaps they were at one time, but they are not necessary now. Just mount to MOS plate. I used Blue Loctite 242 on the MOS plate and torque to 13 inch pounds. I used purple Loctite 222 and torque to 12 inch pounds. I think these are the recommended specs. No problems.OPTICThis optic is fantastic. It sits really nice and low without any distracting hood. The dot is a perfect size with a lot of adjustment.I tried a milled Glock 17 years ago with Trijicon RMRs and gave up because I didn't think the technology was there yet. I started with an RMR RM05G and the glass had some magnification and fishbowl effect and a really deep magenta tint. It really wasn't very clear at all. so, I sold that and tried and RMR RM06 hoping that the LED version would have less tint. It did, but it was still magnified and fishbowled and really blue tinted. The RMRs are supposed to be so reliable, but my RM06 would flicker in and out (very common if you read around). So, I tried the Trijicon sealing plate, and a tape shim, and still had issues. I just gave up and sold it all. I do love Trijicon and have some of their scopes, but feel this is a much better optic for a MRDS pistol platform.The optical quality on this unit is much clearer with much less tint. It also has a less distracting shape without the hood ears of the RMR poking up. It also has a bigger optical window for a more forgiving presentation and shot recovery. I like the Vortex Viper much better for a pistol optic.I also prefer the brightness adjustments on one side compared to up on one side and down on the other. When placed on two sides, it is difficult to remember which one is up or down under a timer or stress. When on one side, it is much easier to know that forward is up and back is down. Also easier to manipulate without much changing of the "thumbs forward" grip compared to buttons on each side. I have no need for an auto-adjust, as I really like to select dot brightness based on the application (speed, precision, transitions, etc.)I selected the Viper over the Venom because of its lower position on the side, as I feel that this makes it easier to use when coming from using iron sights.IMPROVEMENTSThe only thing that I think could be done better would be to relocate the windage and elevation locks so that they could be locked/unlocked without removing the optic or rear sight. They should be located on the side or top.
