Damn it. Try to leave but the Forum pulls me back in. I had one of those back about 10 years ago. Some came in with the Saiga bolt action rifles. Those came in 3 fixed positions. Angled back towards the shooter, straight and angled forward. You can remove the spacer and lower it a bit. Used one of those mounts along with some other parts and made a makeshift scope mount for a Super Vepr. The rifle was of a side scope mount configuration.
