Zubo-pattern beam rifle

For the beam rifle used in the original Halo Trilogy, see Type-50 particle beam rifle. For other uses of the term beam, see here. The Type-27 Special Application Sniper Rifle (T-27 SASR), otherwise known as the beam rifle, is a long-range Covenant weapon.

Service history
The T27 SASR is manufactured by the Merchants of Qikost. As evidenced by its designation, the Type-27 was cataloged much earlier in the Human-Covenant War than the comparable Type-50 particle beam rifle, which shares the "beam rifle" moniker. Though the T50 was encountered as early as 2531, it was not cataloged until 2550 and did not become a particularly common weapon until 2552, which suggests that the Type-27 saw more predominant use throughout most of the war. Despite being supplemented or perhaps replaced by functionally similar weapons, the Type-27 saw continued use among Jul 'Mdama's Covenant forces as late as October, 2558. The T-27 SASR is now the Covenant’s primary long-range special application weapon, used almost exclusively by scouting personnel and designated marksmen. It is ranked a Rare REQ in Warzone simulations, and is available at Level 6 energy while giving 100 REQ points if sold.

Design details
The Type-27 beam rifle is quite similar in design to the Type-50, suggesting that both weapons were derived from the same ancient Sangheili design. However, the Type-27 has a bulkier profile akin to that of the Type-52 Special Applications Rifle. In comparison with the Type-50, the weapon's firing channel is better concealed and is set closer to the muzzle. It features an enclosed focusing crystal compartment rather than its counterpart's open layout. Another major difference is that the Type-27's grip faces straight back, whereas the Type-50's is angled upward; this allows the user to maintain a conventional shooting posture rather than being forced to fire from below the shoulder. The weapon's grip also differs from the Type-52's in the fact that the Sangheili-designed ergonomic grip has been reconfigured to a smaller thumbhole with additional hand grips, usable by multiple species with different hand structures. Through the ionization of hydrogen gas and the use of a linear accelerator, a powerful beam is emitted at hypervelocity speeds, lethally striking enemy targets. The weapon features a 4× to 10× smart-linked scope which will give off a bright purple shine while zoomed in.

Variants

 * Sword of the Faithful: The Sword of the Faithful is the personalized beam rifle of the Prophet of Regret's majordomo. It is an improved T-27 that features enhanced hipfire accuracy, faster heat dissipation, and a higher rate of fire compared to normal T-27 beam rifles. It is ranked an Ultra-Rare REQ in Warzone simulations, and is available at Level 6 energy while giving 150 REQ points if sold.
 * Krith's Left Hand: Krith's Left Hand was reclaimed from the Kig-Yar Pirate Prince's personal vaults by Ripa 'Moramee sometime before the latter became the Arbiter. Unlike other beam rifles, Krith's Left Hand is an advanced T-27 that fires in three-round bursts with one pull of the trigger. A single burst will kill a Spartan in War Games. It is ranked a Legendary REQ in Warzone simulations, and is available at Level 7 energy while giving 200 REQ points if sold.
