The Vepr 12 is produced by "Molot" factory, which also makes RPK-74 machine guns and Vepr brand semi-automatic hunting rifles. All "Vepr" brand rifles and shotguns are broadly based on the RPK-74 light machinegun designs, adapted for civilian purpose and appropriate ammunition.
This shotgun has a very high rate of fire (280). However. it suffers from many weaknesses as low damage (544), short range (4), bad accuracy (63/38), especially hip accuracy; and its low ammunition capacity, which could be burnt out very fast with its high rate of fire.
