+1 to what DnPRK said. Tho, I like the vise block that Brownells and Midway sells for around $35. It is molded to the outside of the upper and has a insert to protect the dimensions of the upper. Also, it helps to have a barrel extension socket to attach to the torque wrench. When I was a USMC armorer (M16A days), the torque set was 30#. But specs and metal do change. Just remember the barrel nut only has to be tightened to a line the gas tube notch. The barrel extension is the part needing to be weight tightened. I head spaced thousands of M16s. I only recall 2 that failed. Most problems were bent and worn out barrels...
