A 12" LaRue Grendel barrel has been requested for years on their forums. Hopefully someday he does it.
IMO I'd just use the BA provided gas block on the Hansen barrel, it will work fine with the LaRue guard. If the reason for adjustable gas is a suppressor you will likely be happier with a Bootleg adjustable carrier, much easier to access and adjust.
