M98C Apex vs Flatline/other upgrades

A word of warning.  Backspin barrels such as the Flatline and Apex are generally upgrades that people either really like or really hate; there is usually no middle ground.  Before spending any money on either I suggest you try both if possible (borrow, rent, etc.) just to make sure you're happy with the result you get.  I also suggest reading section 5.5 of this post.

I personally prefer the Flatline over the Apex, but there are just as many folks who feel exactly the opposite.  (Plus a bunch who hate both of them.)

Edited note:  As requested > "something nasty"

Iam thinkin about doing an a5 soviet ppsh mod, maybe with tacamo drum mag, dont  know what to use for stock ?  wood grian ak47 stock ?  eny ideas?

You will not make one shot one kills with the Flatline at the longer ranges.  (In my limited experience with the Apex, you won't make those shots with it either.)  This is not a problem with the barrels, but the nature of the projectile.  Paintballs are spherical low-velocity liquid-filled projectiles fired at relatively low velocities; all of which are factors that allow environmental conditions to easily affect the projectile in flight.  At the longer distances the affect of things such as wind is magnified because those factors have more time to affect the paintball.  Backspin barrels are good suppressive tools.  Properly used in a woodsball game they can be used to control terrain and interdict the operations/plans of the opposing team, but they are not going to allow the user to sit safely out of range and pick off members of the other team at will with aimed shots.

In regards to tuning there are several things that can be done to make a flatline work better, but the most important one is figuring out what velocity the specific barrel and marker combination works best at with the paint being utilized.

As far as paint goes, anything that is fairly small bore will work well.  Since the paint needs to develop spin on its way through the barrel you want paint that can freely roll through the barrel.

i have found that you have to use the right paint for these kind of barrels or you are going to get way frusterated.... you definetly can not use the cheap stuff
