The Yukon Weaver/Picatinny Rifle Mount is a complete mounting set, with which you can mount your Yukon night vision rifle scope on your rifle. This accessory (fixed mount) is indispensable for attaching, for example, the Yukon Sightline night vision rifle scope (see optional accessories) to your weapon. You can use this mounting in combination with weapons that have a Weaver or Picatinny rail.
