Cheap (cost), great for beginner. There are upgrades and this gun can take a beating
Weaknesses:
Cleaning gun once you chop a ball, the ungrades are limited, lame stock barrel.
Review:
Overall I have to say I really like this gun. Although I am new to this sport it has served me great so far. The one big downfall is cleaning out the gun once you have chopped a ball. It took me 2 hours... yes I know sounds pretty pathetic, but this time includes misplacing materials, re-oiling, and forgetting to put something back (iron sight...). After this frustrating experience, I realized what I need to do next time so it shouldn't take near this amount of time. Also my buddy owns a Tippman A 5, and this gun can keep up with it pretty well.
Conclusion:
Very good gun, I would reccomend it to anybody. Becareful when cleaning it out for the first time, it may get confusing/ frustrating.
