Here is my finished project.  The only other addition would be back up sites.  It is basically a FrankenAR.

Lower: Olympic Arms
Trigger system: JP Enterprise Single Stage
Pistol grip: STARK SE-1
Buttstock: DSA Mil-spec tube with VLTOR IMOD
Upper: Loki Weapon Systems with Fail Zero BCG
Scope Nikon Coyote [BDC]
Flashhider: Smith Vortex

I'm satisfied with my setup!  

Looks great....what tube you running on that?

Looks good to me....how do you like the Stark?

Looks good. Have you shot it yet?  Did it group well and if so what ammo have you used?

The tube is Loki's own design.  You can have 4 full raiils all around, or no rails.  I chose one on top.  They also have 3" rails as well.

I love the Stark.  One thing I never liked about standard AR pistol grips is that their is no "beaver tail" for the web of the hand.  Well, . . . there is, but it is effectively too high up.  So, when I saw the Stark, I was glad when it finally came in and was put on.  Feels great, less angle to the grip, too!

I shot it with a rifle length buffer tube, but not with this new setup yet.  I'm sure it will be fine.  Anyway, the upper may be very accurate as soon as I fully get the scope squared away and sighted in.  I did so initially, just to ball park the scope, . . . using WWB, I was getting around 2" at 100 yards [later found out that one of the rings wasn't fully tight on the riser]..  When I can really work with the scope, that should tighten up, . . . and if I use better ammo!
