DJF,
Thanks. Please see pics I just posted. Receiver and associated parts are in the white. Stainless barrel has the trunion attached. Cocking tube is ribbed like HK and has hanger spot welded on. Everything else(bolt carrier, lower, front sight and furniture is included to assemble a complete weapon. Lower is probably not hk but contract. Not sure of imported or US made parts other than the receiver and barrel. The complete kit did come in a box as a set so I assume it was ready to be assembled.
Thanks,
Trojan
