I bought this to mount on a Horton Vision crossbow. Had read that some night vision was not compatable with crossbows because of forward recoil. Since the Horton is a reverse limb design, I decided to give it a try. The scope mounted easily on the existing Weaver rail and returns to zero each time it is re-installed. Light gain is decent without the IR and since my setup is a 50 yard system, the built in IR is fine to add a little extra illumination. The scope does not magnify like the 4X on the bow, but I am able to shoot 2" groups at 30 yards.
I am very impressed with the quality and performance for this price range.
Pros: Built like a tank
