It won't matter; read the rest of my review........
It's light and it's an insert system, but that's about all I can think of.
Ok, first off, it took Equation forever to get this barrel to me. They would promise they were mailing it that day, I would call 2 days later, and they would promise it would go out that day... etc. After I finally received it, the first thing I noticed was the finish. I got the clear finish, and it was pretty ugly (but I can't hold that against them, since I did have choices of other colors). I went to put one of the inserts in, and it didn't fit all the way in! About 1/16" - 1/8" stuck out of the barrel, which kept me from screwing it into my barrel, rendering that insert useless to me.
I figured I would just call them on Monday (this was Saturday, and I was playing PB on Sunday). I put a couple of paintballs through another insert, and it was a perfect match. When I got onto the field, however, you wouldn't think that. I was chopping paint left and right, and when I wasn't, the paint wasn't shooting particularly straight. I thought my paint was bad, so I put my stock barrel back on, and the chopping stopped and I was shooting darts.
My stock barrel outperformed the Bizerk Pro System. I was thoroughly displeased, and cannot recommend this barrel set to anyone. I am giving it a rating of 5, which is average.
