Well here it is, I call her Veera:
The lower is RRA. It has a 6 position stock.
The upper is a dissipator style 16" barrel from Model 1 Sales. The only assembly I did was mate the 2 and slap bits on the rails.
The rail covers, front grip, scope, and mounting hardware I had stored in the basement.
Removable rear sight adjustable for windage and elevation (standard A2 functioning). The scope is from Tapco (Leapers is the brand). It's 4X fixed with a range adjustment said to be calibrated for 5.56 (I just left it at the 300 mark like the iron sights). It's designed to mount on a carry handle but I had some PAQ-4 (IR aiming laser) and PVS-4 (night optic) hardware lying around that suited this just fine.
I've got the scope mounted so I can still use the iron sights with a bit of obstruction. A quick turn of the self torquing screw and the obstruction is removed.
Lower: $290
Upper: $820
Scope: $40
Rail accessories: Really cheap at the "Army surplus store"
