Few if any.
Review:
This gun is very good and i absouloutely love it the anti chop works like a charm its accurate and theres lots of upgrades. Its a great starter marker or even good one for experienced players.On top of that its not to expensive. I would say if your beggining and you like rec ball woods ball this is the marker for you.
Conclusion:
Get this marker its great. If your a speedballer who wants to try or play rec / woods ball get this marker you can almost build your own marker with all the upgrades. so 10/10
