I have a pile of adjustable gas blocks, wanted that adjustability for suppressor use. Number one thing overall I have noticed is I rarely adjust anything, bunch of different specific reasons for that but facts is facts. I actually removed one from a 300 BO build, it has become part of the secured "storage device" for a suppressor, no need to put anything in there that could grab carbon fouling, reliability requirement called for uncomplicating the gun a bit.
