It shoots extremely fast and DOES NOT use MORE CO2
The trigger is great for that group you sneak up on but dont think you'll be able to pump out enough paintballs to get them all, so the response trigger can get 15 of them out in one second :-)
there is more CO2 traveling and the piston banging so it makes a decent amount of noise, also, having it at 15 bps is pretty costly for all that paint and air if you get carried away if you know what I mean.
it is disputed but in my opinion Co2 is VERY suitable and is perfectly fine for the trigger but there are much better air systems to use..... dont have your gun freeze up or your tank! if you have a hose like me and its cold that works as an expansion chamber warming up the gas
Excellent product.... but you need to have control with using this item
