Handguards that clear a 936 gas block?

AR-15 or AR-10/LR308? JP Rifles is a good option for the large frame ARs, large 1.75" I.D. that clears pretty much all the fat .936 gas blocks out there. Seekins MSCR is another great option for AR15 setups, but they don't offer their large frame forearms for general sale yet.
 
I did say the gas block model. It's a 936 gas block. I need input on a handguard and barrel nut that works with bull barrels.

This is a bit like saying that "I need to know what pants I fit into. I am human." We need additional measurements on the gas block, or the actual gas block model (make and manufacturer) in order to tell you what hand guard it will fit under. That the block is a 0.936 diameter block (that's the inside diameter, but gives no specification on the outside measurements) does not give sufficient information.

That said, I have an SLR sentry 9 block under a seekins rail with no issue.
