I would say the Krink is fake for sure. The carrier appears to fill up the back of the receiver. Also the charge handle appears a little too straight, though I'm not nearly as familiar w/ AKs, especially Krinks to say for sure. I'm sticking with fake though for the carrier size alone. Is it me or does the button for the stock look fishy too?
The M4 I can't really tell for sure, would be easier with a pic of the other side. That pin above the selector looks suspect to me. Looks too big to be an auto sear, and too high to be a Colt's sear block; also the texture and its level of protrusion look odd. Oh yeah, that's not an LMT SOPMOD stock. It lacks checkering and the LMT logo on the latch handle.
Now that I think about it, all the LPK on the M4 look suspect, especially the mag catch. And there's ZERO wear on the brass deflector.
