What is the recommended burst length when firing the PK or RPD machine guns?

The recommended burst length of 6-8 rounds for firing the PK or RPD machine guns is based on the effectiveness of maintaining a balance between accuracy and ammunition conservation. A burst of this length allows the shooter to deliver sufficient firepower to suppress or engage targets while minimizing the risk of overheating the weapon and ensuring that the ammunition lasts longer during engagements.

Shorter bursts might not provide adequate suppression or impact on the target, while longer bursts can lead to decreased accuracy due to recoil and muzzle rise, as well as the potential for overheating. Therefore, a burst of 6-8 rounds strikes an optimal compromise, ensuring that the effectiveness of the machine gun is maximized without compromising the shooter’s operational safety and efficiency. It's essential to understand that machine guns are designed for sustained fire, but managing burst lengths is crucial for tactical operations.
