i have an inferno heat the set up is as follows
inferno heat
double trigger (standad)
ventri bolt (a little softer on paint+increases accuracy)
planet drop forward (5 inch gets the marker in tighter to the body)
sprint pipe
10 inch dye stainless barrel (very accurate)
dye sticky grips
12 revvy (not one chopped ball since i have had this)
next upgrades
smart parts freak system
air system
possible gas thru grip
played with this baby for about 2years and its not let me down yetl.
only about +4/-4 over the crono(not bad for co2)
hope this gives u a few ideas
the dye exel barrels are well worth the money .
