What's so unergonomic about the AK? I'll grant the safety but the Russians don't use the safety on any longarm much unless its going to be slung or otherwise out of their direct control. Lack of a BHO doesn't matter much considering you have to hit the charging handle to release the bolt on the VZ anyway.
Rock-in mags are awkward, especially when moving, but again its not like the VZ is any better there.
