Hey Nation im in a sticky situation and i realllly need some help. I sold my geo 2.1 to some guy and air is puffing out of the trigger frame when it shoots. There is a gap between the top of the reg and the end of the trigger frame where the screw is on the bottem. Air puffs out of there when it shoots, can you tell me how to fix it?? It doesnt leak when it is aired up it just puffs out of that small gap, please help ASAP!
