other than a new barrel
fast, light, cool milling
too fast, higher paint bill, mega bounce, the big hole it leaves
My boss brought this new toy into work and let everyone try it out. This thing is super fast. I got 17-18 bps on ther first try, normaly i can only get 12-13 bps on other guns. A major problem with this thing is that it has a wicked bounce. I fired a few times and stopped but the thing just kept on going. It kept going for atleast 3-5 minutes! I don't know if its just my boss's gun or if its a major problem.
Overall, its a nice gun. Very impressive. If you can afford one, by all means get it and hope that the bounce problem has been fixed and be ready for the big hole it leaves in your wallet.
