PSA says they make them.
The front screw is the gas and needs a 5/64" Allen wrench, flush with the front of the block is full open. The smaller stainless screw on the side is the lock screw it needs a .050" Allen wrench.
Be aware my lock screw was barely inserted and not tightened down at all, glad I caught that before losing it.
Additionally check your gas key on the carrier, mine was not torqued, thread locked or staked. Sadly didn't find that until it stopped cycling at the range.
EDIT:
A long 5/64" driver may be advisable over taking the hand guard off.

EDIT 2:
There are at least two models of gas block with different adjustments (and likely different bit sizes). The info above is for the front gas, side lock variant.
