hi i am sorta new to air cannons (only 1 sprinlker vavle modded cannon), but i want to build a new cannon using a qev setup. can anyone tell me a good place to get a 3/4 qev and how to properly set it up for fireing, also i live in the U.S so sites based here would be better if you know of any(to keep shipping costs down).
