Mirwais Afghan published this on his Twitter feed earlier, of the Taliban deputy district chief for the Chaperhar district of Nangarhar province in eastern Afghanistan. He was recently killed by a U.S. airstrike. His AKM features a Trijicon RCO with what appears to be directly mounted to the receiver cover of the rifle, possibly via a rudimentary method of welding or otherwise non-standard mounting procedure.
Of course, if this is the case, accuracy will most likely suffer greatly because of the severe vibrations of the receiver cover during the course of fire. Maintaining zero will be next to impossible. But was a status piece for a deputy district chief, it will certainly get the point across.
