Hey guys, as I had mentioned in another thread, I just purchased a new Scar 17. So I needed to get a scope for it as my eyes aren't what they should be up close on the irons.
I just bought a used Nightforce NXS 3.5-15x56 scope with the illuminated reticle for $1150 shipped. (hope I didn't pay too much for a 2 year old scope) I know that it may be a bit large for a rifle like this however, I will be using it for hunting and killing predators on the farm and weight isn't an issue for me.

Anyway, I thought before I went and bought something that I may end up not liking, I would ask what base would be best to use?
Should I get a NF base or Larue?

If anyone has this scope, could you comment on the pros and cons?

I have Nightforce 2.5-10 x 42. I went with the Nightforce lightweight rings 1.5in. Very happy with the setup...
Not the same scope, but thought it may serve as a frame of reference for you

Few things.

1. Will you be writing your rifle off as farm equipment?

2. I picked up a vortex razor HD. Went with their mount for 89 because the great reviews. Seems to be a great company putting pressure on the high dollar guys. I saw a few forum posts where they use that mount on a .50. Should be good for my relatively docile 17.

I'm not sure what you mean by "writing it off as Farm Equipment". Do you mean for tax purposes? If so, "No" I didn't know that was an option.

I missed the part where you were hunting, but if you were protecting livestock or other investments on the farm, I don't see why you couldn't deduct and depreciate it as a business expense. The hunting part may not fly though.

ADM Delta mount. DO IT.

Your discription matches mine. I was in the same position with my scars. I tried gg&g and their raised platform. Then i tried american defense and used their raised platform. I ended up staying with the adm set up for my nightforce and horus falcon. I used the raised platform for clearance with buis and for the non-reciprocating charging handle. I like the way the adm and gg&g anchor to the rail better than the larue concept.

Just mounted up the NF 2.5-10x42 in the Seekins AR high rings, very pleased with them. I have used Seekins rings on a few rifles now and they are top notch, if you don't need QD they are the way to go.

ADM is top notch. Haven't had one fail.

I looked for ADM on Gunbroker and there were only two to choose from. (see link below) Do you think this one will work with a 56mm scope? It concerns me that I won't have enough clearance as it's a bigger scope.

Also, I want to thank you guys for the advice. I'm still kind of unsure with which one to order. I see that some of these bases have what appears to be 20 moa of adjustment. Is it necessary to have that? With the hunting rifle scopes I've dealt with in the past I've never seen anything like this.

I've never mounted a 56mm objective scope on an AR-like rifle with a full rail, so I'm not sure if a 1.5" tall mount is enough clearance or not. It will likely be close and depends if you want clearance for scope caps or not. If you get a mount with a built in 20 moa than your clearance for the objective bell will be even smaller, and it's really not needed for this application. It's used to help bias your elevation so you have enough adjustment when going out to longer distances. The Nightforce 3.5-15x56 has 110 moa of internal elevation adjustment, which is more than enough to get out to 1000 yards with .308, which is going to be beyond the practical limit of a Scar 17 with the factory 16" barrel with even the best hand loads. And again, if you don't need the QD feature look at conventional rings like the Seekins. I have plenty of rifles with both and the Seekins rings clamp down to the rail much more solidly than a QD mount does.

You got a good deal, so if I were you I would consider re-selling the scope you have and look at the Nightforce 2.5-10x42 instead. It's really a very nice scope with great resolution that will match well with the Scar 17 capabilities. If you still want more magnification then just get the Nightforce 3.5-15x50 instead as it should clear the rail just fine with a 1.5" tall mount. I have that exact scope on a bolt gun and it does great with the 50mm objective. The only thing the 56mm gives you on this scope is slightly more low-light gathering ability but the 50mm isn't exactly a slouch in this area.

Nightforce also just came out with the ATACR 4-16x42 that has even better glass then their 3.5-15x50 which would also be a great choice for the Scar:
