I asked myself that, and looked at the various non matching or otherwise bubba'd carbines and decided I would do my first RPK or "E4" project on a yugo. call it the Ruchnoy Pulemyot Simonova
I started with a mockup (excuse the horrible bipod, it was jsut a leftover from a bubba rescue. it moves on later)
At this point I was still debating which of these rifles would be converted. The Yugo won, for reasons that will make sense later
another view of some of the mocked up features and comparisons. i haven't even fitted the new bolt and carrie rin to the rescued yugo yet
decision made, and some sanding doen on the stock to prepare for fitting a pistol grip
