Those are all real good pictures of your AKs some are mix-and-match but that is ok they are all AK.
So here are just a few of mine.
My first bought AK is the WASR 10 Hi-cap
This is my first build from a kit Romy RPK on a Coldsteel receiver
Here is my first piece together AK a Romy MD63
And my first hand folded receiver was on this Romy "G" build
But don't go away there is more to come on the next page.
