The madbull v2s are not at all bad barrels, though. Both of Woogie's suggestions are great, and will leave you with a great platform to start tuning from. My personal builds are less all-inclusive, but woogie's will do you just fine. However, I have seen some tests done where the vaccum piston lost some compression, so you might want to use the HD set instead.

Own nub, and use a guarder clear bucking. Close to pure silicon.

Yes, the PDI hop will withstand over 800 fps...That setup will handle up to about 650 pretty well. The lower the better - the ideal is about 490-500.

It is a matter of airseal. You are running at about 550 with a .2, which is a lot of possibility for blow-by with a loose bucking. The guarder clear is a good hop up rubber, but the seal leaves something to be desired.

6.03 V2 madbull, but make sure it is the V2. The V1s are not nearly as good.

I would actually recommend a 6.03 Prometheus barrel if you want one that is not as expensive as PDI and is still steel. The crowning on those barrels I have found to be excellent, by the way.
