Nightforce Ultramount for the ATACR 1-8... Torque Values for clamp and rings?

[M4Fundi]

I have the NF ATACR 1-8 and the matching Ultramount. I managed to lose the paperwork with the mount and do not know the correct Torque specs for the rings and the clamp. I have searched much and found nothing definitive from an Ultramount owner. I have found people say its 25 inch pounds for the rings probably and probably either 68 or 100 inch pounds for the clamp. Does anyone that owns the Ultramount actually KNOW what the correct torque specs are? Thanks!

Mine is etched on the mount.
25 in lbs for the caps and 100 for the crossbolts.

I didn't pop the crossbolts at 100 though, 65 felt tight enough.

Wow 100in-lbs seems pretty high. My NF UniMount calls for 25 on the caps, and 65 on the cross bolts.

Mil-spec and commercial versions have different etchings apparently.
I seem to remember the package had those specs as well.

Finger tight + 180 deg comes out to about 65 in lbs for me.

I have a few, 25 and 68.

mine is the SOCOM version in FDE and has no etching or SS# that I can find. I have read that the "narrow" bolt clamp version is 100 inch pounds but could not confirm and did not want to crank it to 100 if it was 68. I guess I will wait till tomorrow and call NF. FYI, neighbors place caught on fire and then it caught my place on fire and I had to empty my house as fast as I could then smoke and firehoses in my place... you get the picture. So the Ultramount instructions are in the wreckage somewhere... so apologize for wasting your time. Thanks!

Didn't waste my time.
I learned something from this thread.

If I remember correctly, the rings with six screws are the ones that take 100 lbs of torque.

Mine has four screws per cap.
It sounds like the clamp width is the difference.

25 in lbs on rings and 100 in lbs on cross bolts.

Feel like an idiot as it is engraved in white on the mount but you can't see it with the scope in place, so after calling NF for info I removed the scope which was loosely in place to figure eyebox and boom there were the specs looking back at me... Doh! Homer Simpson moment! Thanks Again!
