Gun Flatline

What is a good sniper barrell for a tippmann a-5 paintball gun?
i have an a-5 with e grip and a flatline but i want a good sniper barrel that i can just screw in instead of having to assemble. also the flatline is a pain if you chop a ball. any ideas.( i mostly do woodsball type play not speedball so quality over quantity)
If you liked the Flatline, you could give the Apex a whirl – doesn’t need to be assembled like the Flatline, screws right in and easy to adjust and provides similar backspin to the ball.
I like Freak Kits and Dye Ultralite backs – usually a .689. Sanchez or Trinity Sick barrels are also nice.
