Any, you can match any balls to this thing as long as you have the right insert for it
First thing, its very short, i was surprised when i saw the thing because i thought it was an insert. You can match the barrel to any paint like the freak except the inserts aren't cheap alluminum and won't break. The shortness of this thing makes it easily maneuverable so you can get into the smallest of bunkers. You might think that the shortness of this barrel would cause your fps to drop but it doesn't.
+Dead on accurate
+Inserts for paint matching
Ok, this company needs to pull it together. This thing took like 2 months to get after I ordered the freakin thing. They kept saying "we'll ship it out tomorrow" like 5 times. I was a little upset when i saw the barrel was black instead of clear, which is what i ordered, but the black looks cool so its okay. What really made me mad was the third insert, .689 was missing and there were huge drill scratches in the part of the barrel where the insert goes. When you put the insert in, it covers the scratches but still, that aint cool.
If you want a rating on just the barrel itself, I'm giving it a 10. If your talking about the customer service and quality of equations business I'm gonna go with a 4. Equation is lucky im only rating the barrel on this review....Order this barrel if your a front player and you've got 2 months to sit on your butt and wait for it to get to you.
