It is the most reliable marker I have. It can shoot about any kind of paintballs and it wont break. It is the best pump action gun. If you have around $80 I would go and get this gun for a primary gun or even a back up.
Weaknesses:
The only thing I dont like about this gun is a 10 round magazine but it is nice and compact.
Conclusion:
I would'nt get any upgrades for this gun it is perfect the way it is. This is the gun you should get it you had $80 it is well worth the money. This gun is unlike some other guns it is self lubracating.
