Looks good on that vid Ian, so can we state with any certainty now the 6.5 has been field tested so to speak, would the 6.5 be ok without a doubler( obviously) on an air rifle.22 rf for closer range, like ratting, or rabbits out to say 75 yards, or would the 4.6 still be a better choice? If I like the unit, I would consider getting two, one for air rifle and .22 use, and maybe one for .222 or .17rem as a dedicated fox night vision set up, but I would initially like one for closer range work, cheers.
