Advice on adjustable gas block

[Nuube]

On my Ar15 6arc build, I need recommendations on an adjustable gas block .875. I would like to use a geissele super mod mk8 hand guard 1.35 i.d. that I already have, but not sure which ones will fit without having too little clearance. I want a block with detents so I don't have to worry about any screws backing out. If the geissele handguard doesn't work, what handguard/adj gas block combo would you recommend? The rifle will be suppressed. Thanks

Aero precision, low profile with detents,mine is on a 6 arc, and works flawlessly.

Aero P great restrictive method gas block. Surperlative Arms great bleed off for over size gas ports & suppressor use.

I used an aero on my 350 legend and it worked under my Geissele mk16 hand guard. Cheapest option I could find.
