Jee'z that is a beautiful weapon!! A few months back I saw a your link to your page on this build, and I have to admit to you, that I have copied some of your build I love it so much! Exactly the look and setup I was imagining and then there it was on your page!!
I will be using a UBR stock, and a seekins lower though and a different caliber! When my form 1 comes back I will have to post it up!
Thanks for sharing your build with us, and I hope you don't mind that I copied you haha!</div></div>
I have a 11.5" Daniel Defense/LaRue build pending BATFE approval right now, and once that's done I'm going to be doing a 10.5" Noveske .300AAC Mk18 build (probably next year).
Go ahead and copy the photos.
Here are a couple more that are more current:

I would not be so concerned with accuracy as I would bullet effectiveness on target, if you are pursuing game.
7.5" bbl gives up A LOT compared to even a 16" 5.56 bbl. I averaged 2790fps with 62gr M855 (70deg, almost sea level alt., 65% hum) from an 11.5" bbl, but have not chrono'ed from a 7.5". I would stake a claim at 2500fps or so from the 7.5 with 55gr though.
Not a pellet gun; but definitely not a power house.</div></div>
The big concern with barrels that short is the velocity. I haven't gotten around to getting chrono reading on the gun, but you might be pretty close with the velocity. Hornady has informed me that for SBRs, they highly recommend 55gr or lighter loads. Those loads will fly faster so they'll have better terminal ballistics. I am going to be doing a gelatin test some time this spring with Hornady TAP Urban 40gr and TAP Urban 55gr, Federal Tactical Bonded SP 55gr, and possibly Hornady TAP BTHP 75gr. I foresee decent results with the lighter TAP loads, but everything else is a "MAYBE". Since the gun is designed as a PSD PDW system, TAP Urban loads would appear to be ideal for operational use in that role. Still, I'm curious how the Federal 55gr barrier loads will perform.
