I currently have four Saiga 12’s fully converted w/ all the bells and whistles and have converted for friends and family no less than fifteen Saiga 12’s over the past decade. I bought my first Vepr 12 last November and haven’t looked back. In my opinion we are comparing a Dodge Neon with a Hemi Challenger. Everything about the Vepr 12 is right concerning fit, function and finish. The Siaga’s I have handled well…not so much.
