I decided to clean my AR today, it had maybe 200 rounds through it and I just wanted to see how everything looked.
I took to upper off the lower and while cleaning something felt loose. After checking everything out it was the rings moving on the base. Meaning the scope was solid in rings, QD levers were solid on the upper, but I could move my scope back and forth maybe < 1/16 inch or so. I was able to tighten the torx screws on the rings some and it stopped. My question is how tight should the torx screws be? I don't want to hurt my scope or strip the screws. It was still shooting good groups last week even with it loose 
Thanks. |

Also loosen the upper screws and fully tighten the lower screws, first. The rings have to bottom out against the base, then tighten the upper screws.[/span]
I can't remember if I did this when I installed everything, anyway I'll redo it. Thanks everyone. |

Here is the tricky part. You must tighten the screws with a proper torque wrench. If you don’t you stand a strong chance that you will either under tighten them which means shooting the gun will work the screws loose and usually in the most inopportune moment – you can guess when. Or over tightening the screws will cause crush damage to your optics. Most people who care enough either pay someone who has the right tool to do it or they buy the wrench. Those who think they can do without will always suffer the consequences - its just a matter of time. I have "fixed” so many scopes on the range from people who wonder why they cannot zero the scopes that I lost count – they were the lucky ones. Another good practice is to index the screws with a dot of color paint after they have been tightened properly. That way if they happen to work loose, you will have some warning if you take time to check. |
