no problem i use .689 the other guy uses .689 . both have the inferno heat set up on co2 looking at air later on this year with a up graded diffuser bolt also use 12v revvy used to chop a few balls in early days but since had a revvy not one chop.
no problem with inferno threads as they are the same as the spyders.
blue inferno heat
dye stainless barrel
dye sticky grips
5"eclipse polished drop forward
12v revvy
nothig really special about the set up but do plenty of reserch before you part with you hard earned cash
p.s both of the barrels i have mentioned were brought from planet for under £40
