Almost any sized paintballs fit, looks nice, easy to use, good case
none I can think of
I have used this kit for a while now and am rather impressed, accuracy is great no matter what I shoot, only problem I had was I went to a indoor field and they had 2 paint sizes.. both bores were too small for my smallest bore size, i was floores, such small paint! what woudl happen with a stock barrel.. owch! anyways, other then that it preforms great, looks great and has a nice carrying case, I am very impressed and I got it at a great price.
I have even used this with second and acuracy wasnt darts (but how coudl it be with football shapped balls) but it was ok and very few breaks
I will recommend this kit, its a great price at a great value, great if you use lots of diffrent paints.
