Thanks to Illya Kuryakin on Gunco for assitance in identifying some mystery parts.  Thanks, Ilya!

The long part on the right side in this pic is the ejector door latch, which apparently knocks the ejector door open during ejection.

Compared to AKM grip

Rail Location?

Note rub marks on LH side of carrier.  Possible location for a side rail?

VLTOR receiver pics

Their receiver is best defined as "PK clone" as it is not a true PK styled receiver.  Their lower dimple is actually a welded "plate" that is welded into the receiver.  Their rails are actually machined and riveted (welded?) to the receiver.  As the other images show, a true PK receiver doesn't have these milled/welded components, rather all is stamped/bent into the receiver.
