none. used a freakset on a friends custom mag but mine still shot more accurate.. it pissed the shiz out of him.. =) i was very very happy..
don't use great american paintballs they will break every time.
marbs work well
so do jt's
i'm looking for a better match though..
It's just awesome. During range fire -joking with the guys shooting objects from obsene distances it's wicked.
During game fights- it's accurate but i like to send a extra ball or two to make sure it hits its target. it has a grouping of about 3 inches from 35-40 feet during snap shooting. During range fire it's like a .5 inche grouping of about 10 balls. i get them all on top of each other. IT"S JUST awesome.
Porting makes it a bit of a mess to clean when a ball breaks.
haven't found a perfect ball match.
the front piece's threads aren't very strong.. i'm reaching for bad things here if you can't notice.
it's a great barrel and has a awesome accuracy to match. It's not loud but not too quiet. I'm running HPA so i don't know if there's is any type of CO2 clouds when shooting.
