This may be a dumb question but how much torque are you supposed to use to tighten the grub screws on the Razor turret after zeroing? To clarify it is the three screws that you loosen to allow you to adjust zero.

I have a torque wrench but all the videos and the instructions just say until tight. Are we talking thumb and forefinger tight? 10 inch pounds? I don't want to break it but my elevation knob slipped a few tenths of a mil when I dialled it all the way up and down a few times so it was too loose.

While I really like the scope I find these screws a bit irritating. If you do not tighten them all perfectly evenly your zero seems to shift a little. I think tightening one turret can cause the other axis to shift. The instructions tell you to be careful about this.

Thanks in advance!
 
i just do them finger tight. i do find it to be a nuisance...maybe a little thread locker would help.
 
Turn each of the three screws until they touch the inner barrel, you can feel it easily. Then tighten them down until just snug, don't over tighten them--it is not needed. I know there is no quantitative number to "snug", but use your better judgement and you will be fine.
 
Finger tight should be ok. One issue that could be account for the small error is backlash the reticle is moved on a screw there can be a very small amount of play in this screw thread and due to the way sights work errors are magnified by twice the magnification so very small errors become visible. A simple way to fix this is ensure the last movement is always in one direction ethier elevation or depression and the same for left or right.
 
Thanks for the replies. I spoke to someone at Vortex and the specified amount if torque is 10 inch pounds. I don't have a small enough hex bit for my torque wrench but he said if start to flex the small end of an Allen key with my thumb and forefinger that should be good.

I asked about the zero shifting after tightening and he said that shouldn't happen. That's all on me!
