The story about the 2 hole "Vodka Specials" (coined by bob ash from tromix I believe or maybe it was tony, anywho) was that they were russian military ordered barrels, and I guess the military only shoots the heavy loads so they get 2 gas vents, that got "mixed" up and installed on S12's headed for export. This story came to me via Tom Cole from Cadiz Gun Works (sole warranty provider for RAA) and he heard it from Clyde from Russian American Arms (Saiga Importer). Who knows if it's true but they will fix the 2 holers for free including shipping. And they fix them so they will shoot Federal Bulk pack shells, Winchester is not a consideration.
On the polychoke, once I get mine back from Cadiz, I am installing the non-vented polychoke as I really do not need a muzzle break especially hunting next to people.
