Did you check that receiver with a magnet at the rear were the lug for the take down pins? I wondering as the only steel receiver I have seen is on a .308 model AR and it was fully machined.
The receivers used by Colt, FN, LMT, S&W, DPMS, Armalite, Bushmaster and others are 7075 forgings which is the exact same material used in jet aircraft including the latest fighters like the F-22 and F-35.
