Well, pulled the trigger so to speak. 
Picked up a Sig 516 Patrol FDE. http://www.sigsauer.com/Catalo…ls/sig516-patrol-fde.aspx
Got a deal on the rifle with a Sig soft case and 3 additional PMags. Picked it up yesterday and I am VERY pleased with the fit and finish. Looks like I will be stripping it down and cleaning it tonight with the hope of shooting it this weekend. Already added a Magpul AFG2 as I prefer this style fore grip. Apex Defense Multi-Point sling is shipping soon. Great deal at $20 and well built.
So Optics. Right now I am leaning towards an Aimpoint Micro T1/Larue 751 with the 3x Mag/Larue 755.
Also planning on adding a Surefire G2X Pro/Vltor Offset Mount and the BCM Gunfighter Charging Handle.
Hope to post some pics this evening...
