6/27/24 - This is an original Soviet PSO-1M2-1 Rifle Scope. this is a durable 4 power scope produced by the Soviet Union for their SVD rifles. It has a low light reticle that operates from a switch on the mount. The batteries to the reticle must be dead or not the proper batteries as it does not illuminate. It is a simple design and all components are in excellent condition so it should work once correct batteries are installed. Comes with front and rear cover. Clean glass front and back with a nice reticle.
