Yea, I ran into this with a PSA handguard and an Alexander Arms barrel, which uses that larger diameter too. I'm running the AA non-adjustible low profile gas block, and it fits. Barrely, and I had to file down one of the mounting screws that was sticking out still a bit, but it does fit. Thta's my best suggestion.
If it's a rifle length gas system, you generally don't really need adjustible, is my opinion.
