The '''BR55 Heavy Barrel Service Rifle (BR55HB SR)''', also known as the "Mammoth Stomper,"{{Ref/Book|Id=ENC|Enc09|Page=318-319}} is a select-fire rifle utilized by the [[United Nations Space Command]] and manufactured by [[Misriah Armory]]. Intended as a in-production upgrade, it is a heavy-barreled version of the [[BR55 battle rifle|BR55 Service Rifle]].{{Ref/Reuse|EVG}}{{Ref/Reuse|ENC}}{{Ref/Site|Id=WPDMR|URL=https://www.halowaypoint.com/en-us/universe/weapons/dmr|Site=Halo Waypoint|Page=DMR|D=30|M=08|Y=2021}}

==Overview==
The BR55HB SR entered service in [[2548]], serving alongside the standard BR55 Service Rifle. For decades, the BR55 had steadily gained favor over the long-serving [[M392 Designated Marksman Rifle]]. The introduction of the BR55HB SR led to an immediate increase in the BR55's popularity, prompting all branches of the [[United Nations Space Command]] armed forces, except the [[UNSC Army|Army]], to replace the M392 with the newer weapon.{{Ref/Reuse|EVG}}{{Ref/Reuse|WPDMR}}

==Design details==
As with the basic model, the BR55HB SR is employed as a medium-to-long range [[Wikipedia:Marksman rifle|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 Experimental High-Powered Semi-Armor-Piercing|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.{{Ref/Reuse|EVG}} Despite firing a very powerful cartridge, the weapon is subject to little recoil, even when being fired automatically.{{Ref/Generic|Id=HaloLandfall|Heading=[[Halo: Landfall]]|Subheading=[[Halo: Last One Standing|Last One Standing]]}}

==Gameplay==
===Advantages===
The BR55HB SR has reasonably high power, a decent rate of fire, and high accuracy with its 2× magnification scope. Its range is its primary advantage, allowing the player to engage at longer ranges by leading shots. The BR55HB SR has a slightly lower recoil than its BR55 predecessor and has less muzzle flash, although the rounds fired are still visible in the air; the rifle's updated design also boosts range and accuracy, increasing the effectiveness of the 9.5mm rounds it fires. The scope of the BR55HB SR allows a skilled marksman to easily take down an unshielded target from medium range, making the battle rifle the best alternative to sniper rifles.

===Disadvantages===
Attempting to engage a target at longer ranges requires more rounds and less movement as the rounds become inaccurate over longer ranges. In close quarters combat it is fairly surpassed by the Covenant carbine, as the latter weapon is more capable of performing headshots. Furthermore, its magazine can be depleted rather quickly. The weapon requires a good amount of skill in order to use it. The user must have an understanding of how the weapon works, and what to do with it when a situation arises. Each bullet fired from the weapon can act as a tracer, and can give away the shooter's position, putting him at risk of return fire. While effective at long range against light or unshielded targets, the BR55HB's performance against shielded infantry at close range is extremely challenging; the BR55HB, while still very effective, is not the weapon of choice at close range because of its design, and the fact that it can be easily overpowered by the shotgun and energy sword.

==Changes from the BR55 Service Rifle in ''Halo 2''==
*New reloading animation.
*Decreased aim assist.
*Slightly less recoil.
*Slightly different firing sound.
*Slightly lower rate of fire.
*Decreased accuracy caused by greater spread.
*Slower bullet velocity, requiring greater lead on moving targets.

==Trivia==
*[[WETA Workshop]] made a replica of the BR55HB SR, along with several other weapons, for use in the ''Halo: Landfall'' live-action shorts.
*Sometimes the battle rifle will have one or two extra rounds, causing a half burst. This is caused by retrieving ammunition from a Marine NPC. This can also be achieved if fired and simultaneously meleeing. The weapon would have fired one round, and the melee would have cut off the other two.
*The ''[[Marathon]]'' logo is located on the gun's left side, to the left of the ammunition counter display and roughly above the trigger guard and on the stock.
*There are seven triangles on each side of the Battle Rifle's stock. A reference to [[Bungie]]'s favorite number.
*The rifle seems to resemble the Khaybar KH-2002, HS Produkt VHS-2 and French FAMAS bullpup assault rifles.
*Though the battle rifle is not usable in the ''Halo 3: ODST'' campaign, it makes a small cameo in the level ''[[NMPD HQ]]''. It was later added to Firefight in ''Halo: The Master Chief Collection''.
