new sight, diff barrel possibly if you want it, thats all i can think of.
easy to use
Hard to bunker 2 guys at the same time.
i bought this gun awhile back as a back up or if i got bored and wanted to play some stock paintball. Well to my suprise i thought i was just gonna get an average everyday pump. I was killing with this gun. I loved long balling people so much i kept this gun and used it regularly with my cocker. If your going to buy a stock class marker, go phantom baby.
