We have the 5.5-22x50mm w/ the NPR1. I'm not a big fan of the 56mm.

There is not a big advantage going to the 56mm.

The average size of a human's eye pupil at night is 7 mm and in daylight it is about 4mm on average. If the optic give you a 7mm of exit pupil and you are using it for day use more than half the light will not reach the retina. I have also noticed if you are getting too much light and you look away you see light spots were ever you look and the targets look washedout. On a lot of my scopes I use a light reducer so I do not get the light spots and the washout is not there.

Size of bell divided by magnification = exitpupil. Hare are some examples.
56/22x=2.54mm
56/5.5x=10.18mm
50/22x=2.27mm
50/5.5x=9.09mm
The sweet spots for the 56 and the 50mm at Night and Day use.
50/7.14x = 7mm night use and for day use 50/12.5x = 4mm
56/8x = 7mm night use and for day use 56/14x = 4mm
You are really not getting much advantage over the 50mm. I feel there is a bigger disadvantage and that is you have to go with tall rings 1.00" at the low to 1.25" were the 50mm you can do 0.885".

Thanks for the info CS. Very informative read.

I just bought a NF from Nddodd. I am looking for another NF and will look into the 50mm.
