Whats the best barrel for my Mag?
That’s a very broad question, which has no real answer. There are a lot of good barrel manufacturers. The best thing to do is try out as many different barrels as you can and see which one you prefer. The key is to find a barrel with a bore size that fits the paint you shoot the most. The paintball should fit so that you can blow into the barrel and push the ball through, but not too loose that it rolls through. High quality barrels will be symmetrical and have a very smooth finish in the bore.
