The Yugoslavian (Serbian)-Made Zrak Optic company produced these sights from 1967 to 1980. The M59 was used on rocket-propelled grenade launchers, heavy machine guns, and/or tripod mounts. The Yugoslavian People’s Army used them on the Yugo M57A2 44 mm anti-tank rocket launcher during the Yugoslav Wars. The war lasted from 1991-2001. So “she’s” seen some battle. This optic is new/old stock. Comes with a robust leather carrying case, disassembly tool, and rubber eye relief. The glass is clear and scratch-free; see pictures for reticle layout. There is an up / down elevation.
