The gun has a DPMS lower, and is paired with a Del-Ton A2 rifle kit. Total cost was $606 dollars, not counting magazines. I got three USGI mags at $10 each, and was lucky enough to find one LEO only marked one. Total time took 3 hours, although I was being distracted by teh Busch race. Could have gone much quicker. Spent probably a half hour loking for a missing hammer pin and trigger roll pin. To anyone considering building, I would definitely reccomend roll pin punches. Anyway, here are some pics. Finish doesn't exactly match, and the selector and trigger really don't match. But at over a $250 savings from the lowest priced Bushy and RRA that I could find, I don't mind.
