Well, most of my parts came in the other day, so I've begun my build! I'm only waiting on the upper and magazines, then I can get it put all together. I'll have to get some optics before it can be shot, but I already spent more money than the wife wanted me to, so it'll have to wait!
Surplus Ammo and Arms lower receiver
RRA single stage trigger LPK
DPMS Pardus 6 position adjustable stock
The upper will be a DPMS 16" Carbine, and should be here this week sometime.
Building the lower was actually way easier than I had expected, and short of me making a couple of rookie mistakes, only took about thirty minutes to build. Now it's going to drive me crazy waiting for optics!
