Nightforce ATACR ring torque

[Kauaihunter]

I run SHV’s torqued to 30in/lbs. Zero issues. The equal clamping force is what makes a difference. Bolts and screws stay put a lot better like that. The torque numbers are important, yes. Just as, if not more important, are the tapped screw holes of your receiver/action in alignment and are your rings machined well and matching up? Misalignment can cause damage too. Add over torquing and a crushed/damaged scope is likely. In any case, take a few $1000 or any other price range of scopes and beat them up. All things being equal, the NF probably won’t be the first to fail. That’s where “Bombproof”comes from.

Just torque your NF rings to 25 in/lbs like stated on their package, and your SHV will be fine.

lol- that was probably a very straightforward sentence for you, but it was exactly what I needed to hear. Thanks!

I do 20lb-in on my NF ultrallight rings and ATACR ffp.

Any particular reason you prefer to under-torque them compared to NF's specs?

It's what felt right on the threads as I was torquing them down. I also can't find anywhere that NF directly states 25 is the spec. The only torque mentioned in the ATACR manual is for the zero stop set screws.

The night force torque wrench only comes with a 25 inch pound torque stick.
