NF is signifcantly heavier than hunting optics being considered, is it not? I wouldn't use one on hunting rig although they meet the criteria, but would use a swarovski.
Man cannot stress enough that a scope is NOT to be used as a glassing device. Witnessed a fellow watch other hunters through his scope with a round in the chamber, called it quits right then and there. Will not tolerate someone pointing a gun at others much less loaded. The fart new better too. you will remember that hunter that was shot in Alberta last year, his friend gutted him at 300 yards, that guy did work for me. the guy that died. Needless senseless loss of life. Buy good binos and a cheaper scope if you have to, but don't lift your rifle until you are sure that its pointing at the animal you are going to legally shoot and you are certain if you miss you know where that dang bullet is going. sorry for the rant, it just can't be stressed enough
