CCCP Elcan Scope
A replica of the C79 Optical sight and can be found on military service weapons around the world. If you don't need the scope itself as there are targets at a closer range, you can find built in rubber front and rear sights which are lined up very well.
The 4X30 scope is perfect for mid range sniper rifles or longer range rifles whether it be a GBBR or an AEG. This optic will fit standard Picatinny Rails.
