9mm SBR Build

[Olympus]

Wanted to get some thoughts from other members on a 9mm SBR build that I'm thinking of doing. I'm going with a dedicated 9mm lower since I already have another AR SBR. I'm pretty much decided on a Quarter Circle 10 lower, but have some questions about which one. I have Glock pistols already, so I like the idea of the Glock lower. I'm concerned with the issues of BHO on the Glock lowers. And also the BCG for the Glock lower is about $100 more expensive than a standard ramped 9mm BCG. That's essentially 7 or 8 extra mags I could buy if I went with the Colt lower.

So here are my tentative parts:
QC10 lower (Colt or Glock)
LPK (Anderson without FCG)
Trigger unknown, need recommendations
Standard 6 pos buffer
Carbine buffer spring
YHM heavy stainless buffer
Magpul stock and pistol grip TBD
Vltor MUR 1S upper
9mm BCG
7.5" Wilson barrel (8.5"?)
Handguard undecided, but full length. Need recommendations.
Flash hider undecided, need recommendations

Sorry, didn't read that it had to be completed. I thought this was the correct section. Apologies. Maybe a mod will move it to the correct section and not delete it.
