That is a Romanian PSO scope on an AK receiver rail. That scope clamp is meant for a PSL/SVD/SKS tyope rail and installation. It sits the scope lower to the receiver and further back. It also indexes or "stops" on a pin which extends inside the rar of the clamp. It may or may not match u to many AK style rails. An AK clamp is longer and with an open slit along the clamp. It indexes or "stops" on the closed end of the clamp against the rear of the receiver rail. Not a good set up.B4Ctom1 said:
