That's a new cocking rod and an expansion chamber. I'm just saying that if you say a twister feedneck, new trigger, a drop forward and an on&off aren't performance upgrades, your's aren't.are you joking pal, it has a new bolt, new barrel, new spring set, and a new reg, how do they not improve performance.
a reg actualy changes the pressure of the gas going into the marker, whereas the expansion chamber just provides a space to allow CO2 to turn fully into gas rather than staying liquid before entering the gun.a new cocking rod........or a cocking bolt, please dont be a smart arse.
and i know nothing about tippmanns, or CO2 markers for that, (i have an ion, and i know how that works), so i didnt know it was an expansion chamber, but as it is where the reg should be, isnt it a reg as well?
enlighten me....please
