If it's the roll pin holding the gas tube to the gas block, no it's not directional. Now that you have broken a punch off in there I suspect trouble. I broke one on just recently. Had to get a new gas tube, just left the old tube attached to the old block. I tried with a new punch and some heavy hits with a hammer, once the punch was broken off inside that pin would not budge. Get a new tube, the proper size punch and call it a 20$ lesson.
