The BR55 Battle Rifle is a gas-operated, magazine-fed, mid-to-long range weapon capable of semi-automatic and burst-firing modes. [[XBR55|Prototypes]] of the BR55 existed as early as 2524, and were later used in [[2525]] during the [[First Battle of Harvest|fall]] of [[Harvest]]. By 2548 it had superseded the [[M392 Designated Marksman Rifle]] in use in all branches of the military with exception of the [[UNSC Army|Army]]. In Halo 2 the Battle Rifle fires the M634 9.5x40mm X-HP-SAP round from a 36-round magazine, though in Halo 3 the weapon utilizes the 9.5x40mm KURZ<ref>'''[[The Art of Halo 3]]''', page 57</ref>. Additionally, the weapon features a [[scope attachment]] capable of 2x magnification. It does reasonable damage to enemies, being able to kill most within a few bursts (normally four when enemy is fully shielded), and can easily land headshots on unshielded targets, resulting in a one-hit kill. Its accuracy and range are also reasonably high, being able to hit a target from medium to semi-long ranges. It is highly recommended to always have one on hand on higher difficulty levels.

This titanium alloy weapon is gas-operated with a rotating bolt. Therefore, the charging handle must be racked before the first round can be fired; this will put a round into the barrel. The charging handle used to chamber the round is located on the left side of the weapon and does not move during operation. Once the first round is fired, the gases from that round—and those to follow—impinge upon a gas piston, which pushes back the bolt carrier, rotating the bolt inside and continuing to chamber rounds until the magazine is empty. Once the magazine is empty, the charging handle (even though not illustrated in-game) can either be pulled back and locked or it can be fully cycled after a fresh magazine has been housed. If it is pulled back and locked, then it must be pushed forward once a fresh magazine is housed to chamber a new round. The magazine release button is located on both sides of the gun with an arrow pointing down towards the housed mag in the stock. The ejection port is located on the right side of the weapon. There is also a fire selector on both sides of the ammo display.

===Ammunition===
It is interesting to note the ammunition type used for the battle rifle. It uses a new [[9.5 x 40mm]] experimental round. The [[Wikipedia:7.62×51 NATO|7.62 x 51 mm NATO]] round is a rather high-powered round used on the MA5 and on modern-day marksman rifles and machine guns. The 7.62 mm already has a history of having [[wikipedia:7.62x51_NATO#Development|too much recoil]], which made it hard to control in full-auto in assault rifles. Despite the Battle Rifle's shorter case size, the increase in diameter actually increases the amount of powder present. The level of recoil would be enough to drastically decrease accuracy and inhibit the ability to fire controlled bursts for standard Marines, although for Spartans it should not be a problem.

However, the size of the round would have a problem fitting in the 36-round magazine of the BR55. If a [[wikipedia:Heckler_&_Koch_G3|Heckler & Koch G3]] (which is chambered in 7.62 x 51mm) has a standard magazine capacity of 20 and be the size that it is, it would be hard to see a cartridge much wider than the 7.62mm fit inside of a magazine of the Battle Rifle's size and with a capacity of 36 rounds. The Battle Rifle's magazine would have to be about twice as long as it actually is to hold that many rounds. This is a continuous pattern with UNSC assault rifles; a similar instance occurs with the MA5B. The MA5B has a magazine capacity of 60 rounds, chambered in 7.62 x 51mm, with a magazine size that appears even smaller than the Battle Rifle's magazine.
