Tightening your scope rings TOO much? I'm giving my rifle a good cleaning and tightening everything up. Can I get the screws too tight?


Yes....I'd imagine that the worst you will do is strip out the rings. I can't imagine generating enough compression to compromise the scope tube itself.


You'd be surprised. Depending on the scope manufacturer and scope model, it is definitely possible to damage the tube from excess tightening.

Most steel rings require 15-18 lbs of torque by mfgrs spec.
I use a 5-150lb torque wrench from Harbor Freight that was $10 w/coupon...normally $39.99.
But i have put literally hundreds of scope rings on scopes without a torque wrench. I just did them by feel. A drop of blue loc-tite on each screw will prevent them from loosening up.

I don't suppose I'll worry too much about it. Arthritis makes sure I can't hand tighten very good anymore. \:\)

From the DNZ website;

"Then snug all screws, make sure the bolt will still slide. After you snug the screws you can start tightening them up. An easy way to do this if you do not have a torque wrench will be - Insert the short end of the L allen wrench into the head of the screw. With one thumb push down on the L allen wrench into the top of the screw head, keep pushing down with your thumb and with your other thumb turn the end of the wrench and tighten until it starts to flex or bend. When it starts to flex or bend, hold in place for 3 to 5 seconds. Do the same for all base screws. Then go back to each screw and do it again, like tightening lugs on a car wheel. This will lock the screws in place and it will not come loose. This will give you about 20 to 25 inch pounds of torque."

More often than not you're right, but believe it or not I have seen many scopes with indentions in the aluminum tube from where the rings were probably not exactly straight whether it be from machining or the person that put them on and they were over tightened. I've seen screw heads break off before they strip out in most cases (equally bad of course if not worse). I worked in a gun shop for 7+ years through high school and college.

i have seen scopes damaged by overtightened rings.

Different brands of mounts use different sizes of screws so the recommended torque varies from brand to brand. You can strip or break screws and damage the tube on a variable scope if you tighten too much. Ever wonder why it is harder to adjust the power on some variable power scopes?
