You can use this newly made piece of engineering to replace the bottom mount on your PSO or POSP scope with flat finish or BP-02 SVD mount to make it truly universal. It's now made of B95 aluminum two times lighter than classic AK or SVD bottom mounts. It has two removable stops, the front one is to use for SVD style rails, the rear one is for AK style rails. So the only thing you need to convert your scope from AK to SVD version is to screw the SVD stopper in and unscrew the AK stopper or vice versa.
These separate bottom mounts come without pre-drilled "pin" holes since the holes should be drilled AFTER the bottom mount is installed and the scope is zeroed. The user is expected to pin the bottom mount when the exact mounting position is decided. The item is suitable for converting PSO and POSP scopes. Do not forget to order 4 original screws if yours are in bad shape!
NOTE: If you are planning to use this universal mount on an AK style side mounting rail, the resulting height will be roughly 11mm shorter than a standard AK POSP. This can result in clearence issues for some rifles. Be sure to check for available clearence prior to ordering.
