Bipod

Bipods permit operators to easily rest a weapon on objects, such the ground or a wall, reducing fatigue and increasing accuracy and stability.

For example, the painting "The Long Shot" by Howard Terpning[3] shows native American hunters shooting a rifle with an improvised bipod consisting of two crossed arrows.

Recent advances in manufacture of bipods include use of lightweight materials such as aluminium, carbon fiber and titanium, use of different quick attachment and detachment mechanisms (Picatinny, M-LOK, etc.

or even magnets[6]) and various types of feet materials such as rubber, metal, or a "basket" designed to stop the bipod from sinking into soft surfaces such as fine sand or deep snow (inspired by ski poles and snowshoes).

Starting in the late 2010s, the Arca-Swiss style also gained popularity in shooting competitions such as the Precision Rifle Series since the rail allows for stepless adjustment.

Most general-purpose machine guns , such as this FN MAG , have a bipod to increase accuracy for the full-automatic fire mode light machine gun fire support role.
