Just got the stripped upper receiver. That takes the list to Upper, Lower, Bolt Carrier Group, gas tube, and barrel nut.
Next part expected to arrive is the DPMS Light Contour Barrel with A2 Gas Block. 20" long, chambered in 5.56mm with a 1:9 twist. That should be getting here any day now.
After payday, I'll click "checkout" on the upper and lower parts kits plus a few tools for assembly.
After that, all I should need are the handguards. And some spray paint.
