Particle beam rifle

Particle beam rifles (or simply beam rifles) are a type of sniper rifle system employed by the Covenant empire and its remnants. They fire an ionized particle beam at extremely high velocity, capable of dealing damage comparable to the SRS99 series rifles employed by humanity. Within the type-classification schema for Covenant materiel catalogued by the Office of Naval Intelligence, particle beam rifles are designated as Special Application Sniper Rifles (SASRs). Within Covenant design pattern nomenclature, they refer to the various patterns of beam rifles as Long Rifles.

Design details
Beam rifles are massive weapons, measuring over a metre and a half in length. They operate by accelerating ionised hydrogen particles down a narrow path at immense velocities, allowing them to penetrate most infantry armour and energy shielding with ease.

Beam rifles are commonly employed by Sangheili, Jiralhanae and especially Kig-Yar Snipers. At the outbreak of the Human-Covenant War, the Covenant did not effectively employ these tools, but lessons learned from observing human snipers placed a higher priority on the weapons seeing production and use.

History
Particle beam rifles are a technology of Sangheili origin - having emerged in the species' spacefaring history prior to the Covenant and eventually used alongside other Covenant-developed sniper weapon systems like the and  in service. The sea-hunter guilds on the colony world of Feldokra maintain beam rifles as part of their hunting traditions. However, it was not until the Human-Covenant War that encounters with United Nations Space Command snipers informed the Covenant of how effective marksmen could be incorporated into a tactical doctrine. Accordingly, particle beam rifles were selected by the empire's ecclesiarchy as the most effective option available to emulate Misriah Armory's SRS99 rifle series.

As the war dragged on, particle beams found themselves in the hands of Sangheili and Kig-Yar Snipers - becoming a favoured tool of the secretive Jha'kaar. This led to older Sangheili designs being refurbished for use while the Assembly Forges on High Charity were instructed to prioritise the construction of new beam rifles for the war effort. Accordingly, when the city fell in 2552, the production of beam rifles slowed (though did not stop). In the post-war era, organisations such as the Merchants of Qikost and foundries on Sanghelios, Hesduros, Eayn and other worlds continue to produce them.

Variants
The Covenant does not distinguish the various Particle Beam Rifle patterns from each other (at least, not to the obsessive level that the Office of Naval Intelligence tracks every refinement), and simply groups them together based on core components and intended use. Whatever their casing style and aesthetics, all are charged particle beam cannons of prodigious power – capable of killing shielded infantry in one or two shots, depending on accuracy.
