Should work with just about anything as long as you can access the lever. The biggest issue is going from full open to full close they way it sticks up higher at the 12 o’clock position could present a clearance issue. But if it’s a short Handguard and it is exposed just in fron it would work.
The other gas block they sell is adjustable with a key. You could set it for a moderate gas position and control the rest with mass say using the JP VMOS bolt and SCS.
Yes it’s designed for their hand guard on a rifle length system. But could work on others as well, but not all. The low profile one should work with all.
