A1+Phantom Kit? Which barrel length. My Deep Fire tightbore barrel is 509mm long. And I think I might need a PSG-1 barrel. Is that true? In estimate, I think the barrel might be around 550mm-600mm.. I don't know, I'm not too much of a pro and I'm leaving this question up for the most advanced players and softgun technicians.
