The stock barrel is ok, but you may want a smaller bore barrel later.
It has good accuracy with a stock barrel and isnt too loud. Works great on CO2 in all weather conditions. Looks very nice, a definate head-turner on the field.
When I first got it, I didn't realize the velocity adjustment screw was almost all the way out, and it did some full auto badness which chopped balls. But turning down the velocity to about 280 fixed it just fine. I got home and cleaned the chamber and the ball detents (real doozy to clean those detents are!). Ever since I cleaned it all out and well oiled it, its been working like a charm.
A definate must buy for someone with a tight budget or just for someone thats seeking a good looking and good performing gun. It is worth the price and then some! The ball chopping was rather minor, but it did ruin two hoppers of balls (only had about 50 balls in them at the time). But once you get the gun broken in and cleaned, you wont be feeling anything but joy from this gun. So don't let my experiences change your thoughts on this gun.
