Will consider trades for Glocks or whatever you have that is comparable in value. For Sale is One like new Envis 3rd. generation Night Vision Monocular. This item is in like new condition aand has been used very little, works great. The black picture shows the view that my eye saw the green shows what you see with the scope. It has a built in infrared light, you can't see anything when you turn these on with the naked eye but looking through the ENVIS it looks like you turn on a maglight. This thing is awesome and it will be a great addition to someones collection. You can walk through the woods in complete darkness without being seen and can see just fine. It is really amazing to look through this scope. Will consider trades for nice weapons. Retail is $2700.00 Make your best offer, it is also listed on Ebay and whichever sells first then its gone. ENVIS (Evader’s Night Vision Imaging System) is a rugged handheld night vision system for operators who must be prepared for covert night movement. Night movement is the best choice for evasive movement, but it is generally discouraged because of difficulty navigating in the dark. The ENVIS is the survival tool of choice, designed specifically to overcome obstacles and hazards when moving at night and successfully evade hostile territory. The ENVIS is USAF approved for flight survival vests. It is a lightweight night vision pocketscope that fits in one hand for direct viewing. It can easily convert a standard still or video camera into a high quality night vision recording device. It attaches to the objective lens threads of most cameras for temporary nighttime applications. The removable objective lens can be replaced with any C-Mount Type lens for increased range and magnification.
