, but with two legs. It provides significant stability along two axes of motion (side-to-side, and up-and-down).


On firearms, bipods are commonly used on rifles to provide a forward rest and reduce motion. They are also seen on other long-barrelled weapons. The bipod permits the operator to rest the weapon on the ground, a low wall, or other object, reducing operator fatigue and permitting increased accuracy. Bipods can be of fixed or adjustable length. Some can be tilted and also have their tilting point close to the bore central axis, allowing the weapon to tilt a little left and right, allowing a quick horizontal sight picture on uneven ground and keeping the operator close to the ground. Bipods are for the most part folded away forward, not back towards the shooter, and sometimes fold into vertical foregrips.

Some bipods used for rifles allow the rifle to swivel or "hang" near its bore axis, offering a more stable shooting position with large and heavy aiming optics mounted.
