I could probably get away with tightening (scope caps) by feel, as I've always done in the past. I never had anything come loose. Then again, I could have been stretching the threads just the same. Looking what's available out there, prices are all over on these inch/pound tools. I need a range from 0-30 in/lb. I don't need top of the line, but I don't want bottom of the food chain either. I want something I can pass on to my son later. Help me out with some suggestions so I make a good choice!!
