[ARCHIVED THREAD] - Picatinny or Weaver mounts for flat top?

I want to order a 30mm scope mount for my Bushmaster M4 and I see the mounts can be had in either Weaver or Picatinny ..... Which do I get? I thought both rail systems would take the same scope mounts.

My mount moved

I put a Burris picatinny mount on my flat top. I tightened it up as tight as I thought I should but noticed after the first range trip the mount had slid backwards. It has about 1/16" fore & aft movement.

The instructions say to tighten the nut between 65 - 100 inch pounds Is that excessive? I can borrow a torque wrench at work if need be.

65 is standard
