Is there room for an A2 style front sight post without interfering with the muzzle device. I could use an adjustable gas key in lieu of adj gas block. Will I need adjustable gas for non supressed only?

The gas block journal isn’t long enough for a front sight post. There’s only enough room for a small gas block. Unsuppressed you won’t need an adjustable GB, but if you shoot suppressed you’ll want one.

If you’re set on a FSP, cut a mid length barrel to 12.5” and you’ll have enough room. Or, if you enjoy redundancy, you could do something like this

All the gas blocks

There isn't room on our 11.5", but we make a carbine length 11.5" for Brownells that has room.

Here's  the Faxon 11.5 Carbine Gas Gunner from Brownells. Very accurate, have not suppressed it though.
