My Joo buddy's 1970's East German AK kit build with Polish barrel. Blued, not cerakote. Very few of these around and quite collectable. Most of these went to Hamas and the Iranians.
Gunsmith friend of ours who does great builds put it together for him.
That is really really nice!!! Has he looked lately for a east german lower grip? They are out their to be had.
That radom barrel and east german train assembly is a real durable combo.
