I do have a quick question. When I finally got over to my brother's to machine the barrel .. his DINOSAUR CNC mill that he used to drill it had too much run out and instead of having a gas port of .118 I ended up at .125.
Any foreseeable problems with the larger gas port?

Reason: dinosaur CNC .. not a drill press ..
