This is a mounted scope bag for when you have the POSP on the rifle and when it's stored separately. It will protect the scope from brush, scratching, clogging and dirt when moving through all types of terrain. Protects against rain, snow, mud and much more while still allowing you to get a shot off whenever you need to. It is military issue and is currently used by the Red Army. Fits all POSP and PSO scopes as well as other scopes which are no longer than 430 mm and have outer objective diameter less than 80 mm. Has one big and four small inset pockets zipped separately. Really great camo case.
