other than more weight I have no clue.

I have a 56mm and I love it (so much I ordered a second). It is my understanding that it should offer a bit more clarity but I have not compared it to a nightforce 50mm. Its definately better than my leupold mark 4 but I guess thats a no brainer.

56mm they say offers 10% more light to come through at low light conditions. if ur not doing the majority of ur shooting at dusk or dawn, prob not a big deal.

The issue with ar type rifles is the flat base to barrel joint. unlike a bolt rifle, there is no drop to allow for a larger objective with same ring height. Meaning, the ar will need higher rings for a 56mm than a 50mm. higher rings = holding ur head higher. on an ar rifle, that is where it gets awkward is holding ur head up higher or finding a decent cheek peice to raise ur head to assume proper sight alignment that is repeatable.

my 0.02...

Who is they??

The benefit is a larger exit pupil, but unless you are going with a benchrest power range you shouldn't notice much difference, even a 5-22 offers a 2+ exit pupil with the 50.

I'd go 50, just because I like my scopes lower on AR's than most.

i am wanting it low as possible so, thats the route i will most likely go

I'm useing a 8x32x56 on my Ar-10. It might be a little much for that rifle but it works for me. I'm useing 1.25" rings with the 1/2" spacer and the ojb. sits .345" off the top rail.
I can play with the rings and spacer some to lower the scope some but for now it's fine.

A Badger 22 MOA rail and Badger 1" height rings worked well with my 56mm S&B. Feels like a perfect height when behind the rifle. You could probably go with .885s with the 50mm objective but I would recommend the 22 MOA rail either way.

"They" is an article I read reviewing multiple scopes in some magazine which I dont remember right now.

So you got me wondering and so after I checked NF website, the exit pupil on the 50mm is 9.1mm and the exit pupil on the 56mm is 10.2mm. crunching some numbers results in a little over a 10% increase in size of the exit pupil. It is my guess that the pupil size IS a direct correlation to the amount of light that is allowed to pass through. Numbers dont lie.

I dont know where you got 2+ from...

Of course if the corelation is not linear, which I could not tell you, then this is not the case. I DO know that a larger pupil = more light, I am just not sure of the correlation (linear, exponential, sinusoidal, etc)

Given these numbers are at the lowest power setting (5.5x)
At 22x, its closer to a 5% difference.

So, again, if ur not shooting in low light conditions, and also want a lower mounted scope, I would go with the 50mm.

I have the 56mm mainly cause I do a lot of coyote and varmit calling, and dusk/dawn is when I do the majority of my work. That being said, I would be hard pressed to actually be able tell a difference..
