APS are a Hong Kong brand IIRC. Most of their guns have been pretty poor quality qith the exception of the rather fantastic UAR. These blowback AKs are known to have fragile internals however APS may have upgraded them to their latest run of version 3 gearboxes. I'd be wary. More good AKs to consider would be the CYMA CM045 and Dboys RK01WS.
