We'll see what the mfrs say.
I actually have more faith that OmniSwivel might move the o-ring up a hair.
Changing the chamfer is also a good solution, but I wouldn't put it on the lathe as is. Shortening the chamfer also means shortening the barrel, which is part of the problem.
And I'm sure AA will say they need the thick nut for heat dissipation.
I thought of grinding the Omni-Swivel nut short, as you suggested. This has two consequences:
1) It means that this Omni-Swivel is ONLY good for use on an M1, because
2) A short OmniSwivel nut will cause the center shaft to bind against the barrel end on any other regulator with a longer barrel nipple.
I'd be satisfied with an alert and a recommendation to switch to the standard nut if you're gonna use the Omni-Swivel.
