Second time shooting the battery stoped working right after I took it off the charger so recomend new one. New barrel all stock barrels suck. Also if you are using hpa you should get a new grip regulator I would not trust the stock one. Other that these minor up grades this gun is a very good gun and I think that any one who says otherwise is not a real paintball player.
this marker is a very good marker for the price (I got mine for 160 bucks) it is way better than a e99 out of the box. takes spyder threads and intimidator bolts and spyder triggers.
