This is a Yugoslavian M59/66 SKS converted to select-fire by the Bosnians during the Bosnian War. Because of the arms embargo on Yugoslavia, the Bosnians were short of weapons and had to improvise from what was available. (Another improvisation was the field expedient sniper rifles, one which is on this site.)
A new select-fire trigger group was added, similar to a M2 carbine, and a new larger magazine was added, similar to Bosnian AK mags. The underside where the magazine feed lips meet was milled out, there was a notch added for the magazine to lock into, the bolt hold open was removed, and the bolt was made thinner. There are holes on either side under the finger grooves of unknown purpose. Also scope mounts could be welded on for night vision scopes off other weapons.
To allow importation, the full-auto trigger group and larger magazine were replaced with standard SKS parts. Some magazines have been imported otherwise. Only a handful of these rifles have been imported.
This rifle also has some writing on it, which has an initial and component with unknown meaning.
