Assembling Grendel upper, would love any tips/tricks/info to help accuracy

k then I'll torque to 30, 30, and then next hole. no biggie.

Actually, was more wondering if you had secret info that led to the higher torque values! Most accuracy recommendations have you torquing the minimum above 30, and there have been specific cases of heavy torque leading to accuracy problems. Apparently the norm for mfg's was a much heavier torque than required or specified by Colt and the GI armorer manuals.

Here's the link for the brownell's tool. LR1995 on this forum has used it and recommended it. The idea looks sound, largely removes the upper receiver from the equation.
