Tighting iron sights on rails?

[tvfreakarms]

I was curious to know how tight should the iron sight be tighten on the rails of my ar? Just got an mi rear sight and obviously not to loose but I don't want to over do it.

i use a gerber to give them a 1/4 turn past handtight so that i know they wont come off. Have not lost one yet... (looking for some wood to knock on now)

I was thinking about getting a wheeler fat wrench. It has a torque indicator to about 65in lbs. It maybe worth it.
I just used the hex key that came with it and gave it some elbow grease. What is a gerber by the way? I looked it up and there is a lot of different type of tools.

Depends on the size of the screw and the material it screws into.
40 in-lbs is good for a #8 screw in aluminum or 50 in-lbs in steel.
50 in-lbs is good for a #10 screw in aluminum or 60 in-lbs in steel.
