Pso type scpoes, Zenit vs Kalinka

[Ninjacat]

Are Zenit and Kalinka pso scopes one in the same? Or is one better than the other? Are they junk, do they hold their zero? Do the turrents and rings get loose after 1000 rounds. Or are they a good, cheap, all around scope that does the AK justice? I'm checking in cuz I think I might get one for my SAM-7 Carbine.

Different factory, same government spec........buy either pso-1, they are a good scope for the money
