My experience shows that all night vision scopes are in general bigger than regular daytime scopes. I always take a lot of different stuff when go hunting so I feel every extra pound and it is a big deal for me. My CO-MR is rather lightweight and compact so I can keep it in my bag until darkness. The whole concept of making something like this system was doomed to success. You do not have to re-zero anything you just put the system in front of your scope and that is it. No additional settings are required. I would recommend this device to all hunters who used to have 2-3 day long hunting.
