Honestly, I took the role on in milsim paintball years ago, so it was a easy transition. Anyway, while we tread into off topic here are two links first in
http://www.milsimempire and
OSOK paintball sniper forum
Problem is I am also partial to all things belt fed too. Anyway I got started into airsoft in general after getting heavy into milsim paintball after taking a 15 year break form paintball entirely. A lot changed while I was gone from paintball. Now most of the time this stuff sits in its locker as my field time is spent on airsoft now mostly.
My ION is a better marker for it because it is quieter, than any of my three Tippmann, The Tiberius mag fed pistol is awesome and the Tiberius fin stabilized paintballs make let you have range and accuracy the role deserves. Compare the range of a .68 cal paintball to the Tiberius first strike ball.
Max Range of a standard paintball - 337 feet
Max Range of First Strike Projectile: 510 feet

two of my three tippman A5s on with a OPs Gear Mk48 SAW shroud and the other with a B5 bull pup mod, The B5 has a flatline barrel. My ACU load out shows my cross draw Tac 8 pistol 4 magazines of 8 69 cal each. 12 140 round pods mk48 SAW shroud Tippmann A5 on a remote. I am close to heat exhaustion here because we were both ghillied right up to before this photo was taken.
alright its a heavy gunner load out but now you know what I sort of look like (I am in ACU here)
works better when I veg the ghillie doesn't it especially not in ACU.
