Mag Setup Question

[SPECIAL_K_06]

I was wonedering if the following setup would work?

ule body
12' .685 cp two piece barrel
ULT
Y-grip
Classic valve
Level ten bolt

My other question, is the CP two piece a good barrel for a mag? and is that a good barrel size? My final question is, how many bps would i get out of a level ten bolt with, ULT, y-grip, and a classic valve?

you cant use ULT with the classic valve.
