USP-1 or "Tyulpan" (From Russian: Унифицированный Стрелковый Прицел, первый образец, Unifitsirovannyj Strelkovyj Pritsel, pervyj obrazets, "Unified Firearm Sight, first model, GRAU index 1P29) is a Soviet/Russian universal optic sight, used on the AK rifle family (AKMN, AK-74N, AK-74M, AK-101, AK-102, AK-105), the RPK-74N, the PKMN and the PKP "Pecheneg" and is designed for quick-mounting and quick-detaching. Compared with an open mechanical sight, the effectiveness of firing at targets is increased 1.2 to 2 times, and the time taken to conduct a firing session is reduced by 60%.
