MP-155 is a gas-operated semi-automatic shotgun manufactured by Izhevsk Mechanical Plant in Russia. It was created on the basis of MP-153 and superseded it in production.

MP-155 is designed for firing cartridges developing pressures up to 1050 Bar (including lead and steel shot).^[1]

Due to the use of aluminum alloys (from which the receiver is made), by placing a mechanism for adjusting the impulse of the automation engine in the gas piston (which improved the balance of the gun) and using a lightweight aiming bar (arched type), the weight of the gun was reduced compared to the MP-153.^[1]

The butt and fore-end can be made of wood (beech or walnut) or plastic.^[1]

The new model differs from MP-155 in a few ways, like length of the receiver of the 12/76 version was reduced (which provides additional weight reduction). It is also available in versions for lefthanded shooters, has dovetail mount and other improvements.^[1]

New version was presented by Kalashnikov in 2017.^[2]
