Who makes a good low profile gas block that will allow a midlength or riflelength forearm on a carbine gas system?

PRI comes up a lot when talking low-profile gas blocks

You can see one here on ADCO's site-------->Scroll down to see the PRI or these --->More lo-pro GBs

I saw another recently and am looking for it, but will let you consider this in the mean time

eta: The one I was looking at was part of Knights Armament parts kit

You can see it here

It includes the folding front BUIS. I will give you the thead that discussed it at length if I can find it.

IIRC, it was embedded in a discussion on the new URXII KAC rail

I was looking at the KAC low profile, but not the one with the sight attached. I just need something that will fit under just about any forearm, price isn't an issue.

I have the LArue, it's nice .
