Mounting the Viper
The Viper red dot is shipped from the factory with a low rail mount that clamps to both a Weaver or Picatinny rail.
1. Attach the low rail mount to the Viper using the included hardware.
2. Attach the Viper 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 Viper down and forward and using the supplied hex wrench, firmly tighten down the clamp.
In addition to the supplied low rail mount, an optional riser mount is included.
