Do as IG says and buy the BCM upper tonight to save $50!
Get a 9.0, not 10.0.
But I like this one better if using a fixed FSB. Gives you a little bit more room for mounting a light.

My 12.5" with an FSB cutout hand guard.
Speaking of regret, I’m regretting my newest 12.5" has a DD rail instead of Centurion.
Oh well, there’s always some fanboy willing to pick a DD up…
Are the cutout rails in stock? I was simply going by the item being ready to go. Although with this build, that isn’t a major issue.
This can be an outright win - your buddy has a decent rifle, and with some more funds you can have a really impressive SBR.
The Kino with the Centurion Cutout rails was going to be my second recommendation, after a Centurion barreled 12.5" on a VTAC Extreme 11" (on pure cost and weight, the latter wins, the former is more flexible and includes a front sight post). Or a pure Centurion build - their rail or a DD. Hard to come up with a config that isn’t awesome.
Either way, you can be absolutely in business with that, an SBR’d BCM Blemish lower (or buy a stripped and assemble it), DD fixed rear sight and the aimpoint/mount of your choosing (PRO or H-1 on LT660).
