What mags are these? I am new to 5.45x39. My guess is they are Russian made and imported through Bulgaria. I can't tell if this is considered Plum or Black.
There are stamps near the front locking lug. There are no arsenal markings or mold numbers, the mag bodies look like they may have scrubbed. Brown internals, all mags have 1 witness hole.
Thank you in advance, I have never collected Russian or Bulgarian firearms/mags.
