Adjustable Gas Block - Need Recommendations

[mtnlvr]

I have the clamp on SLR adjustable gas block under an M-LOK hand guard. I can reach the adjuster with a longer, standard end allen key even with my TBAC Ultra installed (a ball end would be a little nicer). The gas block is a snug fit under the hand guard. So much so, that I cannot install any M-LOK accessories in a couple of slots on the bottom. The clamp to hand guard clearance is about 0.055", maybe a smidge less clearance to the clamp screws. It's a dia 1.36" ID PSA hand guard.
