Barrel upgrades

[WingZero]

I have a Shutter that I would like to get a new barrel for.
I am looking for a 12" to 14" barrel that would be a good as an assault-weapon (rapid fire and storming), but remain highly accurate and could sub as a sniper barrel if need be.
I was thinking ACI 0-grav, Taso Winforce, or the Kingman Twilight.

Does anyone think these are good for what I am looking for (if so which is the best), or if anyone has any other suggestions I should look into please let me know.

(and please add web-pages that I can purchase the suggested barrels at)

Thanx

I had a Taso Winforce and it sucked. It wasn't any more accurate then my stock barrel. I used it for a couple games and took it off. So I bought a 16" Boomstick and it works awsome. It's super accurate and I highly recommend getting one.

Dragon Series 2-Piece, 14Inch, Spyder 119.99 I have seen this and it works good. The only thing was the guy that used it sucked (his first time out). But this made him look good.
