The new gun of the Izhevsk Mechanical Plant MP-155 retains all the best qualities of the previous model - the MP-153.
New model is distinguished:
reduced weight due to the placement of the mechanism for adjusting the pulse of the automatics engine in the gas piston (which simultaneously improved the balance of the gun) and the use of a lightweight aiming bar (arch type); reduced length receiver receiver chambered for 12/76 (which provided additional weight reduction); improved ergonomics due to: - new design of the neck-shock absorber, - the ability to adjust the lowering of the butt-ridge due to interchangeable inserts between the butt and the receiver, - an improved USM design (reduced trigger stroke, increased fuse button size). The MP-155 gun also acquired new consumer properties:
Execution for left-handed shooters, The ability to install additional sights (optical or collimator sights), The possibility of staging an additional barrel without fitting fit in a repair shop. In the design of the gun introduced a cut-off mechanism that allows you to turn off the feed from the store and quickly make a shot with a different cartridge than those with which the magazine is equipped.
