you could route the air differently, use an inline reg , spring it down to get a steady 50 psi out of it, put a tee on the side and take the tank pressure to the back of the mag and to the inline, then come out of the vertical with aa lpr line incognito, inside the rail.

OR, you can do it however you want.

but that rock reg under the barrel doesn't really bother me too much.

not any different than a matrix, cocker, bushmaster,freestyle etc.
