He couldn't afford a promaster and the hpa tank for only $350.
IF you can find one, Used Ion/B2K pds + 68/4500 hpa and deal with the stock barrel. SIGNIFICANLTY faster, eyes so they won't chop, just better overall guns than a trilly.
If not, Wrath + J&J Edge + 20 oz. co2. Same ~ price as the trilogy, SIGNIFICANTLY faster, can still run co2, won't break since it has eyes.
make sure that if you do get CO2 and the wrath, anti-siphon the CO2 tank. This will make your gun more consistent and will reduce the damage done to the gun by CO2
