Weaver/ picatinny - pk-as - Zenit PK-AS Dual Black Dot, Red Dot Tactical Combat Sight

Sturdy and hefty optic, super clear lenses with huge amounts eye relief (almost full arms length). It's belarusian and ships with russian manual/instructions, neat but unreadable for me. Only complaint I have is that it didn't ship with a battery, and the battery housing in the optic was a little dirty/scuffed up. It ships with a stitched camo cover and an allen key inside plastic bags, wrapped in the russian manual inside a cardboard box with russian markings.
