Hey guys, I am looking to do the valve mods for my at44 but can someone tell me which size should the screws be? What I understand is they have to be 6-32 and 4mm long but I am not really sure about it, also do I need to tap the valve ports before plugging them? Or is it just to take a screwdriver and plug the holes like if it was wood? Thanks in advice
What was the small hole drilled into the tube for in that regulator Video?
