had this gun for 4 yrs now, bought as standard gun added a stock + flatline barrel and e grip.
NEVER had any balls break in gun EVER.
would suggest this gun to anyone novice or expert (very accurate and very fast ),cyclone feeder system delivers 16 balls a second.
i still use both grips depending on how much i'm going too spend as this gun can eat balls for fun with the e grip on.
if you do buy this gun all i say u will be very happy with it.
