Overall markings are cyrillic, including a range chart for use with the AK rifle and RPD machine gun, with a standard Soviet-style rail clamp mount at the base and a power switch fitted with a glow-in-the-dark tip (contents unknown, but still good). Included with the scope is a matching numbered green-painted case, matching numbered alloy battery carrier (battery not included), a plastic parts carrier, two spare capacitor tubes, two spare lamps, additional small spare parts, and a Cyrillic-printed log book.
