The Venom red dot is shipped from the factory with a low rail mount that clamps to a Picatinny spec base rail.
Note: If your firearm is not already equipped with a Picatinny base rail, this type of base may be purchased from many firearms dealers.

  1. Attach the low rail mount to the Viper using the included screws.
  2. Attach the Venom to the Picatinny base rail, making sure the recoil lug is solidly seated in the base groove.
  3. Check to see that the clamp is fully down and hooked around the outside of the base.
  4. Press the Venom down and forward toward the muzzle and firmly tighten base clamp screw using large coin or flat blade screwdriver.

Sighting In

After mounting, an initial sight-in of the Venom red dot at 25 yards will be helpful. Final sight-in should be done at the desired distance (typically 25-50 yards). Using the center of the three-shot group as a reference, make the necessary adjustments for windage and elevation correction. Using arrows for reference, adjust dials in the direction you wish the group to move. At 25 yards, each click will yield about ¼ inch of adjustment. Fire a three-shot group at final preferred sight-in distance (25-50 yards).

Maintenance

Cleaning

The Venom red dot will require very little routine maintenance other than periodically cleaning the exterior lenses. If desired, the exterior lens may be cleaned by wiping with a soft, dry cloth. When cleaning the lenses, be sure to use products that are specifically designed for use on coated optical lenses such as the Vortex Lens Pen and FogFree Cleaning Kits.

  • Be sure to blow away any dust or grit on the lens prior to wiping the surface.
  • Using your breath, or a very small amount of water or pure alcohol can help remove stubborn things like dried water spots.

  • I have the Vortex Venom 3 MOA. Is is possible to get the wind age and elevation screws replaced. I need both screws, I have started to strip the screws due to adjustments. Also the battery cover screw is starting to strip. Could I get a new battery cover.

  • Hello , I have a vortex venom on a marlin .357 / 38 special . It is shooting 6 inches low and I have adjusted it up all the way possible. Is there any adjustment to be made to raise the point of impact so I can zero the rifle correctly. Thanks in advance

    • I’m having the same issue with a 10mm s&w pistol. 2 inches low at 25. No more up adjustment.

    • Here is an official response from Vortex taken from one of the other blogs that addresses a similar problem:

      There could be a few factors at play. To confirm, we recommend only 12 inch/lbs with Loc-Tite or 15 inch/lbs dry of torque to secure the red dot to the mounting base. If over torqued it can affect the internal components, which would potentially limit your travel and ability to sight in your optic.

      To ensure the optic is functioning as it should I would recommend running the optic’s windage adjustment all the way to the left and then the right. I would do the same with the elevation to ensure there is not a burr on the internals affecting your ability to dial your elevation adjustment higher. The optic has 130 MOA of total travel, so run the elevation first 65 MOA from either direction to get it close to the optical center. For the windage, it has 100 MOA, so 50 from either direction would get you back to the center. This also helps to confirm you’re getting the full travel of the optic. You should have slightly over 4 rotations of the elevation and just over 3 for the windage dials.

      If that does not work, it is likely a situation where you have ran out of elevation adjustment based on the unique alignment of your firearm. This can happen due to machining tolerances on a wide variety of firearms, so it is not uncommon. I personally had a similar situation with a Mossberg 835 and our Venom Red Dot I use for turkey hunting. In a perfect world, every firearm would be square, but that is never the case. You could have two of the same exact firearms a serial number apart off the production line and they will zero with the same exact make/model red dot different. This is why optics have gross windage and elevation adjustments to accommodate the firearm, but some may need more adjustment.

      The final solution would be to acquire a 1 degree shim from UM Tactical.. This shim would sit between your optic and the base. It would operate in the the same fashion as a long range shooter utilize a 20 MOA picatinny rail to gain elevation adjustment. This shim would give you approximately 60 MOA of elevation adjustment, which would instantly raise your POI roughly 15 inches at 25 yards, 30 inches at 50 yards getting you back on target.

      Hope that this is helpful.

  • I was impressed with vortex. They really stand by their warranty. I emailed vortex to let them know that I lost my battery cover on my venom red dot .
    Within 24 hour they responded and in days I received a new battery cover part of their warranty.
    Great customer service

    Thanks vortex

  • I mounted my vortex venom on my ATI 12 ga over and under ventilated rib . I put a weaver scope base on the ventilated rib then mounted the venom to it . The red dot did not coincide with the proper height required to center the rectical so I got a riser mount 1/2” high and mounted it under the venom sight . It then aligned properly giving me plenty of adjustment area to line up the red dot on the 50 yard target . The venom vortex sight works perfectly and maintains its setting .I use the gun at turkey shoots and also for hunting geese . I have a red dot on all my pistols and shotguns .
