Rifle Scopes NF Ring Question

[Jackalope33B]

I got a pair of NF Rings, and the little piece of paper in the NF Ring box said to torque the ring cap screws to 15in lbs. Now in the manual that came with the NF Scope, it says to torque the ring cap screws to 25in lbs. Which one is it? Or am I reading something wrong here lol

Re: NF Ring Question

15 in. lbs. should be the minimum and 25 in. lbs. should be the maximum.

I torque mine at 20 in. lbs.

Re: NF Ring Question

What NF manual did you see that in?

Re: NF Ring Question

Its not worded like that in any NF manual. Just common torque values for the application.

A consistent torque on all the fasteners that is more than 15 and less than 25 inch pounds is what is important.

Re: NF Ring Question

Here is what my NF manual says.. I would hate to go to 25in lbs, and possibly strip the small threads. Its almost double what the little label in the scope ring box calls for.

Re: NF Ring Question

25 inch pounds is ok. Its not foot pounds. 25 inch pounds is not that much torque on those screws.

When I said it is not worded like that, I meant as 15 minimum with 25 maximum.

The 15 inch pounds listed on the small tag is very conservative.

I have tightened hundreds of bases and cap screws to 25 inch pounds. Never broke a single one.

Re: NF Ring Question

Just got my email back from NF. Here is what they said about the ring torque:

Hello,

Thank you for your patronage in Nightforce Optics.

We have recently increased the recommended torque spec to 25 in/lb.

All Nightforce rings are mounted in pairs prior to packaging to ensure they are aligned to proper spec. There is no need to lap the rings as they are held to a tolerance tighter than the thickness of the anodizing and removal of any material could change the surface contact area between the ring and optic enough to damage the optic when torqued down.

Please let us know if we can be of further support.

Respectfully,

+1, for 20 in-lbs. I would rather error on the low side. The scope is rock solid in the rings, no slipping, maintains ZERO perfectly.

Re: NF Ring Question

Dstewart51, I have the exact setup you have for a rig.

I was wondering based on your signature if your Savage came with the 20 MOa base, some folks are saying that they did not get one from the factory and that it was zero moa.

thanks

Re: NF Ring Question

I have yet to hear of someone who's 110FCP came with a 20MOA base. Looks like all of the early batches came with 0MOA Aluminum EGW.

Re: NF Ring Question

should I be able to see the 20 moa drop by looking at the gap between the top of the reciever and the bottom of the moa rail...should be thinner toward the front right, less gap, or is it milled on top to provide the slope.

Thanks

Re: NF Ring Question

Let me ask you guys something. My NF Ultralites were torqued by a gun smith at 18 in/lbs. He also applied some rosin between the rings and scope for a little extra "grip". Should I have him torque the scope rings down to 25 in/lbs or leave them as is? By torquing them down tighter, will this affect my zero at all on the scope?

Re: NF Ring Question

Yes, changing ring cap screw torque could and most likely will affect your zero. 18 in pounds should be plenty, especially with the addition of some rosin which I don't feel is necessary.
