That was a good idea, I measured it up with square, and another ruler, measured from the arm of the op rod all the way up
The tube, from the base of the tube to the end, it’s out 1mm from the base to the end, that probably is pretty close to what out at the op rod and gas tube.
Good call on than one, thanks 45ACPKING
Any chance of getting the date off this? 14 = 2014?

you could also take two straight edges..... rulers, strips of straight wood.... metal bars ect… as long as they are very straight and about a foot or so long.
Place one along the oprod tube and one along the oprod arm and then compare parallelism.
I check the arm from the side and the top edge.
You want to see it nice and true.
This will rule out a bent oprod as a possible culprit of the contact between barrel and oprod saddle.
kinda came to me as an after thought but worth checking
