It is very important to get 1. The scope rings or mount evenly to the rail 2. Tighten the rings down equally - many people are doing wrong right there in those 2 areas. I have never used a torque wrench, to me it is like a meat thermometer when you do BBQ. I think it may be useful but used wrong can do as much damage as using a too big of a wrench or drive. You overtighten very easily. When you are at it, buy a level as well, lol. Never had one, my eyes are just fine. Again, you have to have your rifle level, then your rail, then your rings, then your scope. OMG, my head is spinning.
Like those guys on youtube "we don't get sponsored by the manufacturer selling this $3,000 scope", yes sure.
