Bipods are attachments typically reserved for use on light machine guns or sniper rifles; however, it is possible to equip them on assault rifles and carbines. They allow the user to provide more accurate fire from a stabilized position while prone or from a raised surface.
Prior to Battlefield 3 the bipod was only a visual accessory, offering no benefits to the weapons which it was attached to.
In Battlefield 3, the Bipod is an attachment for light machine guns, sniper rifles, assault rifles, and carbines (excluding the AKS-74u, the G53, the A-91, the QBZ-95B and the MTAR-21). It is featured in both the Singleplayer and Co-Op campaigns and in Multiplayer. Light machine guns are equipped with this attachment by default.
Several weapons found in the Singleplayer campaign have a Bipod attachment;
- An M249 SAW used to defend the bridge in the mission Operation Swordbreaker
- An enemy RPK-74M in the mission Operation Swordbreaker
- An M98B in the mission Operation Guillotine
Several weapons found in the Co-Op campaign have a Bipod attachment;
- The M249 SAW used by Player 2 in the mission Operation Exodus
- An M39 EMR in the mission Operation Exodus
- The Mk11 Mod 0 used by both players in the mission Drop 'Em Like Liquid
- The Type 88 LMG found in various levels.
The bipod is unlockable for many weapons (excluding sidearms, personal defense weapons, shotguns, some carbines, and gadgets) in Multiplayer mode.
The bipod is deployed by aiming near the cover or ground you wish to deploy it on and it will automatically activate. The bipod only deploys on something that is chin high, after a patch. This takes just over a second, but provides an instant boost to the accuracy of the weapon with the bipod, as well as decreasing felt recoil, most significantly with light machine guns.
As a general rule, the heavier the weapon deployed on the bipod is, the higher percentage of recoil reduction and accuracy increase follows. Carbines mounted on bipods for instance, will remain less accurate than other weapon types, as well as not having their recoil reduced by nearly as big a percentage. In addition, high optic zoom scopes will have their scope sway removed. The recoil when using a bipod will still increase when suppressed.
It remains deployed only for as long as the player remains stationary, and limits the radius in which the player can aim the weapon. It is possible, however, to override bipod deployment by simply continuing to move while going into sight mode. The player can also take cover behind some objects by aiming in the opposite direction (placing their body out of sight from certain angles).
There are several glitches associated with the bipod, such as a tendency to deploy in unusual locations when near a wall, making it difficult or impossible to fire accurately. However, since the bipod doesn't provide any passive negatives to a weapon, it may be advantageous to use in conjunction with weapons that doesn't draw large benefits from using the foregrip, in favor of being able to lay down minor amounts of suppressive fire, or for increased long range accuracy.
The Bipod returns to Battlefield 4 as a usable attachment for most primary weapons. As in Battlefield 3, it provides bonuses to accuracy and recoil when deployed, while limiting mobility and the opportunity to equip a weapon grip.
In certain cases, the bipod may interfere with leaning over low cover. PC players may bind the and functions to separate keys if desired.
Notably, if a weapon is equipped with a bipod and fired from the passenger seat of any vehicle, it will have the full advantages to recoil and stability of a deployed bipod, although the bipod is not actually deployed.
Suppression still causes the user's aim to wander when using a bipod, though not to the same degree as when handheld.
Unlike previous appearances, the bipod in Battlefield 1 is automatically deployed whenever the user is near a suitable surface or is prone, more quickly deployed, and has negligible effect on the user's mobility when idle. The user has more ready access to the accuracy and stability bonuses provided by the bipod. Bipods can be used on top of nearby vehicles and crouched players.
Deploying the bipod no longer restricts player's turning radius, and the accuracy bonus provided by the bipod is drastically increased, to the point where recoil for most light machine guns becomes completely negligible when using the bipod.
Some weapons such as the M1909 Benét-Mercié and Perino Model 1908 use an aesthetically distinct but functionally identical Tripod. The AT Rocket Gun, an Assault gadget, also has an integrated tripod — the player must have the bipod deployed in order to fire the weapon. The Tankgewehr M1918, the main weapon of the Tank Hunter elite class, uses the same mechanics.
- In the beta of Battlefield 3, the bipod was usable on the AKS-74u; however, upon release, this feature was removed.
- When using the bipod in conjunction with scoped optics (the 12x Ballistic scope for example), the scoped view will have a larger radius than when not using the bipod.
- In some instances in both Battlefield 3 and Battlefield 4, the bipod deploys itself in mid-air automatically when the player is reloading while sprinting but will retract automatically when either the reload or sprinting animation ceases. This does not occur if the player either reloads while stationary or reloading when walking but not sprinting. It is currently unknown why this happens.
- In Battlefield 4, players can deploy a bipod on top of another player's held Ballistic Shield.
