The H.C.A.R. (Heavy Counter Assault Rifle) is a modernized version of the World War II BAR 1918 developed by Ohio Ordnance Works, Inc. The weapon is lightweight, with a reduction almost 8 pounds compared to the BAR, and is completely customizable, but still fires the BAR's .30-06 Springfield round (7.62x63mm) and uses the same Browning 3-position gas system. The H.C.A.R. uses a pistol grip, adjustable stock, multiple Picatinny-type accessory rails and can feed from a 30 round detachable magazine, compared to the BAR's 20 round magazine.
— In-game description
The HCAR is a weapon featured in Battlefield Hardline.
The HCAR is unlocked after the Hot Shot Case file is completed alongside the SCAR-H. The HCAR is the second available battle rifle in the campaign. It has a rate of fire of 470 rounds per minute and is shown with a 20 round BAR magazine unlike its multiplayer counterpart.
The HCAR is a purchasable Battle Rifle for the Law Enforcement Enforcer. It fires the .30-06 round and deals heavy damage, but it has a large amount of recoil when fired fully-automatic. Compared to the SCAR-H, the HCAR has a slower time to kill at the same ranges, but has ten extra rounds in its magazine and swifter reloads.
The HCAR has a high first shot multiplier as well as high vertical recoil, and as such benefits from the addition of an Angled Grip for accurate long range shooting. Conversely, a Stubby Grip and Compensator can help improve recoil manageability in close quarters.
- Like the MPX, the HCAR's singleplayer appearance in 2012 is anachronistic, as the real weapon was announced in 2013.
