OSV-96 .50 Caliber Sniper Rifle

The OSV-96 Sniper Rifle, a folding anti-material rifle implemented in the 90s as the Russian competitor to the Barret .50 Caliber Rifle.
The barrel is able to fold at the front of the receiver for easier carrying and storage. I couldn't find much information on the scope at all other than it is possibly a POS 13x60 scope.
