Going (mainly) by the "signature" muzzle/barrel extension and no bayonet lug on the FSB and the stock. That's a Czech Small Arms (D-Technik)/Czechpoint vz. 58. Built entirely in the Czech Repbulic.
Not sure on your "CAI" markings. But I seem to recall that Century did import some gun for Czechpoint around 2009, before, etc. Usually it was Waffen Werks, TGI, for those markings before Czechpoint started importing them themselves.
I can't tell by the pictures. But if your rifle is 7.62x39 and came with and uses two 10 round, clear polymer mags. Then it's one of the rifles that Czechpoint used to sell that didnt have the mag well opened up to use standard 30 round mags. So you'd be stuck with the 10 round, single stack mag. https://www.czechpoint-usa.com/10-round-single-stack-plastic-magazine-complete?l=5
Not an "AK".
