All American - it shot almost the same, but I think that the Freak Jr. is more accurate at further distances.
Smart Parts Epiphany, Halo B hopper, 72/3000 PMI Tank
I use Nelson Hot Spot and they work great, Diablo Dusk work great too.
It has a front and a back which is nice.
None so far
The barrel came stock on my new Smart Parts Epiphany and when I was shooting it for the first time I forgot to turn on the eyes and broke a ball, but didn't know it until I was done shooting because the balls weren't flying all over the place like with some stock barrels. The barrel looks sweet on my Epiphany and on my friend's ION. The barrel is VERY accurate, hitting the top of a 2 inch round pole from 60 feet.
I would recommend the barrel because it is a good upgrade for any gun.
