BR55HB Service Rifle (Combat Rifle)

"The BR55 Heavy Barrel Service Rifle (BR55HB SR), also known as the "Mammoth Stomper," is a select-fire rifle utilized by the United Nations Space Command and manufactured by Misriah Armory. It is a heavy-barreled version of the BR55 Service Rifle. As with the basic model, the BR55HB SR is employed as a medium-to-long range marksman rifle; though its barrel is 25.9 centimeters (10.2 inches)longer than that of the BR55, the BR55HB SR performs almost identically to its predecessor. It fires M634 X-HP-SAP round from a 36-round magazine, which fits flush in the receiver. The magazine housing is built directly into the underside of the stock of the rifle and is located behind the grip. Though the BR55HB SR is a select-fire weapon, it is most often used in its three-round burst mode. Despite firing a very powerful cartridge, the weapon is subject to little recoil, even when being fired automatically."
