The new Arsenal MG-1M (a PKM variant) is taken to full-auto and and slow-motion task by Larry Vickers. The new machine gun is a blend of the original design but makes use of some modern tricks including a fluted and finned barrel that uses a CHF and chrome-lined barrel to increase the longevity of the barrel (Arsenal contends 30%).
While difficult to tell by the video, it looks like Arsenal has used QPQ/melonite/isonite to increase the longevity of other components.
Details from Arsenal:
The 7.62×54 mm ARSENAL Machine Gun MG-1M is a powerful individual automatic weapon designed for use against enemy troops, firing points and light air targets by means of automatic fire.he 7,62 mm ARSENAL Machine Gun MG-1M is designed and intended to be used in the countries in the Middle East, south-east Asia and Africa with tropic and desert conditions.
The design is specially intended and allows operation of the weapon in heavy climatic conditions (tropic and desert), which are typical for the regions of Middle East, south-east Asia and Africa.
MG-1M belongs to the automatic weapons operating by the principle of taking off an amount of powder gases through a special opening in the wall of an immovable barrel and their effect imposed on the breech block carrier piston.
The Machine Gun operates in automatic fire mode.
In general, the 7,62 mm MG-1M preserves all technical characteristics of PK and PKM, but the results of the endurance test show that the System life and the barrel life of MG-1M are increased in about 30% in comparison with PKM, which is a result of some changes of the mechanisms and the increased cooling surface of the barrel.
The barrel is manufactured by the method of cold radial forging that resulted in bigger hardness and better structure of the material.
The barrel bore is chromium plated. The other differences are:
– the new design of the flash suppressor-compensator;
– butt and hand guard made of high quality and resistant glass fiber reinforced polycaproamide, not effected after heating by direct sun lights, corrosion and humidity resistance, light and firm.
It fires 7,62×54 mm cartridges with ordinary bullets (light bullet mod. 1908, heavy bullet mod. 1930), armour – piercing incendiary and tracer bullets. A 200 round link metal belt, held in a metal box feed cartridges in.
The Machine Gun MG-1M can be easily mounted on the Tripod TAR-MG, produced in Arsenal JSCo., (the name of the machine gun becomes MG-1MS). The tripod allows conducting fire with Machine Gun at horizontal or vertical targets, as well as thus efficiency of fire is increased.
