NightForce NXS 12-42x56 Illuminated NP-R2 Reticle

I've been longing to get this: NightForce NXS 12-42x56 Illuminated NP-R2 Reticle.

Has anyone used this at max power? I have a Premier Reticle 20x50 and it gets dark when cranked up to 50x magnification. Is the NSX dark?

Any help is appreciated, thanks [img]images/icons/smile.gif[/img]

Consider the 22x

The 40x only magnifies mirage and impurities in the air. You can see 30 cal holes at 600 yards and 50 cal holes at 1k w/the 22x and you have much more clarity and brightness.

exit pupil will affect your ability to see at high magnification.

Divide the objective by the magnfication, or 56mm/42. The result is 1.33 mm, which is certainly on the real small size. Consider that the human eye can dilate to 7mm at night in a healthy youngish person. Explaining why one of the most popular and useful binocular version is 7x50. [img]images/icons/smile.gif[/img]

High mag is going to give you a darker image than lower mag. Lots of 1,000y BR shooters like and use the 12-42x56 NF. But the sucker weighs more than two pounds, and certainly won't be a practical hunting scope for low light conditions.

I'm with the other poster -- if you think you want to use this rig in the field, then you'd be better off with the 5.5-22 (which also has a LOT more internal elevation).

Or, compromise and get the 8-32, which will get you excellent low light performance at lowest power, with a 7mm exit pupil.

I have the NF 8x32 NXS. I love the scope the clarity is more important to me than the magnification. I compare the NF to a couple of other top models in low to no light and it beat the tar out of the others. It is hard to beat the NF.

Re: NightForce NXS 12-42x56 Illuminated NP-R2 Reticle

My mates have Nightforce and I manage to play with one in the field but never tried the 12x42x. The 8x32 was real easy on the eye even at 40-50 yards, and that surprised me.

I'm also keen on an USO SN9. Love their external elevation (+/-300). The model I'm looking at costs about US$4-5k (12-50x) ouch!!! Do they offer discounts? I am not familiar with USO so I was thinking since I have a 50x now I should go for a 50x next. And since my Leupold gets dark when cranked up to 50x I was thinking I may need 70-80mm objective. But I might not be comparing apples to apples here. To see clearly, I prefer something that can show very clear and sharp pictures at +1000yards. I prefer not to spend more than $2.5k on a scope. Would you know what models are compatible at 1000yards up? None?

Back to the Nightforce [img]images/icons/grin.gif[/img] Affordable and clear. (I think). So, you reckon at 44x is gonna be dark as well?

Re: NightForce NXS 12-42x56 Illuminated NP-R2 Reticle

I have a BR version Nightforce 12-42x56mm with an NP1-RR reticle. It's clear as a bell on a decent day to 40x then darkens up. I routinely shoot groups at 35-40x. At dusk, 22x is about it, but still very crisp. Bullet holes at 600 are easy to see in the white...in fact a black target paster will do well as a target at that range.

I was first drawn to the NF by a buddy who had two. When I lined up on a plastic 2 liter soda bottle at 600 yards & centered on the little white cap, the reticle was clear & fine enough to allow the cap to be quartered with white showing in all four quadrants. SOLD!

Re: NightForce NXS 12-42x56 Illuminated NP-R2 Reticle

Hallo Mate [img]images/icons/wink.gif[/img]

Remember when using high powered riflescopes, there will be an appearance of "darker on the higher powers" due simply to the exit pupil and how the human eye sees the light reflected off what is being observed, then refracted through several lenses. To determine any optics exit pupil, you divide the size of the objective lenses by the ( power ) magnification. This will yield the exit pupil in millimeters. For the human eye to view all the light being transmitted through the scope, an exit pupil of about 4 millimeters is ideal. But when you are using high magnification or smaller objective lens, the exit pupil can get below the optimum 4 mm's in a hurry. This does not mean that you can no longer see the light and image transmitted, but because of the smaller exit pupil factor, the image appears darker.

For example:

Leupold 8.5x25x50 with a Premier Reticles 20 x 50 power boost
50mm objective divided by 20x magnification = 2.5 mm exit pupil
and / or
50mm objective divided by 50x magnification = 1.0 mm exit pupil

Nightforce 12-42x56
56mm objective divided by 12x = 4.6 mm exit pupil
and / or
56mm objective divided by 42x = 1.33 mm exit pupil

Those figures, combined with the knowledge that Nightforce scopes are equipped with excellent glass, will show that the Nightforce will convey a brighter image at its highest power setting.

However:
Leupold 8.5x25x50 with a Premier Reticles 20 x 50 power boost
50mm objective divided by 42x magnification = 1.19 mm exit pupil

Versus

Nightforce 12-42x56
56mm objective divided by 42x = 1.33 mm exit pupil

For a difference of 0.14mm's when set at the same power settings. Not really a whole lot of difference.

So, it's a give and take situation. Because of the larger objective lens and lower maximum power, the Nightforce will convey a brighter image, but at the expense of more bulk and a loss of the highly prized reticle set in the first focal plane.

My two cents is that 0.14mm's is not going to transmit enough light to justify the additional $1200 - $1500 USD's for a new scope. Nor is ANY daylight optic on the planet worth $4-5,000.00 USD's!
