I did this one cheap.
the lower is a forged hi-quality 80% and it was given to me. A machinist friend and I finished it up.
I bought the DPMS upper, 4 postion stock, 3 mags, complete lower parts kit for around $470 at Knob Creek last spring from the DPMS booth.
I then bought the rear sight seen in the lower front of the pic for $76.
After that I found out the scope in the pic is a Ukranian calibrated for 5.56 with a lit red reticle normally $180 and my Dad got it in a box of gun parts for $40. I usually monted it on the rail directlty and it is a great scope. It's on the carry handle for the pic.
I bought the other accessories in the pic over time and Versa-pod was free.
Recently I traded the upper, stock, lower kit , rails,a nd some other stuff for a Saiga .308 converted to P-grip with Ace folder and scope. I still have the lower, Versa-pod, light sling, scope, and mags of course.
I'm gonna get a 20 inch standard A3 with the picitanny front gas block and maybe and a free float tube too. I liked this setup, but the Saiga was too goo fof a trade.
