pilot, evo2 y-board, ccm clamping feedneck, 20oz co2 antisiphoned,
any paintballs will work because you can change bore sizes, i use monster balls
-Not a million holes for porting
-Good smooth finish inside
I got this barrel kit as a Christmas gift, at first it didn't seem like anything special but then again i was new too paintball (and still am a noob) so i didn't understand the different bore sizes. with this you can use practically any paintball, get a perfect or very close too it paint/barrel match. it shoots great, looks great, the case is very fancy, never had a ball break, and most importantly it doesn't have porting all the way down the barrel just at the top.
i would recommend this product to anyone who is in the market for a new barrel the price is great, 7 different bore sizes so you can get almost a dead on paint/barrel match. It looks good and most importantly shoots very accurately.
