Requesting feedback on 2nd and final upper build

I’m looking to have a slightly more accurate upper put together for my second and last build.

My no. 1 rifle sports a 16" standard middy BCM upper, 9" DD Omega, BCM BCG, Troy BUIS, standard FSB, standard CH (waiting on a BCM gunfighter CH) and a SF G2 with a TNVC upgrade in Vltor mount. It sits on a Stag lower, CMT LPK with a colt disco, SSA trigger, CMT mil-spec stock kit (BCM stock kits weren’t out yet, IIRC), Moe grip and Magpul CTR stock.

For the second upper, I was thinking of having MSTN put together an upper around the DD upper receiver that I bought from Rainier using a Noveske N4 light barrel. However, the Centurion 16" lightweight hammer forged barrel has caught my attention. I like the barrel contour much better than the government profile, which is why I dig the Noveske as well. Plus, it costs a little less. The potential headache about going with the Centurion barrel is that I don’t know who I could trust to have assemble the upper correctly. I TRUST MSTN to do a good job should I send them my stuff. I guess, I could call them and see if they wouldn’t mind putting together the upper using a Cenutrion barrel instead of the Noveske. If it’s a no go, who would you guys trust to do a good job?

ETA: I see that the mid-weight Centurion barrel is on back order. I’m surprised as it would seem that the LWT would be the more desirable barrel. It sorta has the same contour as the Noveske.

Update: Just found out that Centurion does not offer a fixed front sight, which is what I prefer.

Just wanted to clarify that the above is incorrect. Centurion can slap on a FSB for ya.

If you order directly from Centurion, they can put a fixed front sight on it for you.
