Introduction

The Goryunov SG-43 is a Soviet World War 2 era medium machine gun. It was developed to replace the old Maxim M1910 machineguns in Soviet service. After World War 2 most tanks and armored personnel carriers were fitted with variants of the SG-43.

Design

The SG-43 is a gas operated weapon using a long stroke gas piston. It uses 250 round non-desintegrating belts that feed from right to left. The SG-43 uses spade grips and is always mounted on a two wheel mount or vehicle as it is very heavy. A heavy quick change barrel is fitted to allow for continuous fire. The improved SGM uses a fluted barrel.

Firepower

The SG-43 fires the 7.62x54mm round from 250 round belts. The only fire mode is fully automatic. The cyclic rate of fire is 650 rounds per minute. The long and heavy barrel allows it to be used against area targets out to 1.000 meters.

Users

The SG-43 was used by Soviet forces from the later stages of World War 2 until the mid 1960's. It was used by infantry and mounted on many combat vehicles as a pintle mounted or coaxial weapon. Most Soviet allies received the SG-43 and it has been produced under license. The SG-43 was replaced by the PK machinegun in Soviet service. Most users replaced the SG-43, but it can still be found in third world countries.

Variants

SG-43

The SG-43 is the original model of the SG-43 family of medium machine guns. The SG-43 fires the 7.62x54mm round from 250 round belts and is operated by the spade grip. It was mounted on a metal two wheel carriage and was often fitted with a gun shield. The SG-43B has a dust cover over the feed and ejection openings. The Chinese Type 53 is a direct copy of the SG-43.

SGM

The SGM is a modernized version of the SG-43B. The SGM has a fluted barrel and the charging handle is moved to the right side of the receiver. It was mounted on the same two wheel mount as the SG-43, but later on also on more modern tripods. The Chinese Type 57 is a direct copy of the SGM. The SGMB has a dust cover over the feed and ejection openings.

SGMT

The SGMT is a variant of the SMG for coaxial installation on tanks and is solenoid fired. The Chinese Type 59T is similar to the SGMT.
