This is a barrel buy of Mcgowen 22in 30 Remington AR barrels with associated AR Performance bolts. H at ARP has only 12 bolt and extension he can offer so the barrel buy is limited to 12. The barrels will be fully fluted and target crowned. I have not made the order just gotten a quote. Price will be in the 425 range for the whole thing more as i get more info on shipping. We each need to pony up about $130 sooner of the total to pay ARP for the bolts and extensions so the can ship to Mcgowen. 

This is the stats i'm going to pass him

22 inch Stainless Steel 416R - in the black finish
1x10 twist 
.093 gas port
11 degree target crown
.998 over the chamber
.998 tapering to .750 at the gas block or step down to .096 to the gas block 
.750 out to muzzle

I need feedback on what profile to choose.

The ARP bolt and extension fits in a standard AR-15 upper but a larger ejection port is recommended. You can have or mill some material off the bottom of a AR-15 upper or order an upper with a larger ejection port.

Should we change the twist to 1/12 for better accuracy with the 150gr bullets?

A 1 in 13 twist rate will fully stabilize up to and including 175gr projectiles in 30 caliber.  The slower twist will also allow higher velocities with lower pressures.

What are the chances of going with a 4150 CMV instead of stainless. Also, what upper receiver are you guys going to pair these with? Will the Mega slick side heavy duty work? Would a VLTOR MUR work?

I think Crome Moly is what i'm going to go with but 4150 isn't an option its just 4140. Any upper will work but one with a larger ejection port is preferred other wise you may need to machine it larger.

You can pm constructor for a bolt and order a barrel from McGowan.

You need to talk Constructor into making bolts and extensions first.
