AR barrel nut gas tube alignment

[bodiebill]

Using the standard mil spec barrel nut I get close to alignment, but need another spoke turn for complete alignment--about one more notch will do it
I do not want to over tighten the nut, staying within max 70 ft-lbs.
Should I use a shim? Emery the nut face?
Or just go ahead and tighten staying within the 70 ft lb max.

go ahead I don't think 1 spoke will matter.

AR gas nut timing

Anderson Machining in KY said that they initially torque to 30 ft lbs then remove the torque wrench and wrench to correct alignment.

I would add to that never exceed 80 ft/lbs.

so torque to 30 then crank up the wrench to 80 and tighten till it aligns. if your wrench indicates more then 80 lbs you need to fix something.
