Very sturdy built - Armasight Vampire 3x CORE IIT Night Vision Rifle Scope

I like the scope as it functions like it should. I have taking a few coyotes with it after using thermal to scan while on stands calling. Gives you a positive ID of target. The eye cup does fall off easy as said in other reviews but i installed a small zip tie around it and hasnt fell off anymore. The scope is a little bit bigger than most but i will put up with the weight over other smaller NV optics because of the crisp and clear image it has. Battery life isnt as bad as i expected unless you are in really cold temps. I added an aftermarket IR because i wasnt impressed with the one that comes with it. My biggest draw back to the whole unit is i wish it was more that 3 power magnification. To get the 6 power magnification you have to step up to a unit more than double the price.
