The Sniper Rifle System 99C-Series 2 Anti-Matériel, abbreviated SRS99C-S2 AM[5] or just S2 AM,[1] is a commonly-utilized sniper rifle in the arsenal of the United Nations Space Command. As evidenced by its designation, it is part of the SRS99 Series.

Overview[edit]

Design details[edit]

Main article: SRS99 Series

The SRS99C-S2 AM is a gas-operated, magazine-fed sniper rifle chambered in the powerful 14.5×114mm cartridge.[2] Its rate of fire is semi-automatic, and it is typically fed by 4-round detachable box magazines.[3][4] As befits their sniping role, they are issued with optics, such as the Oracle N-variant scope.[6]

A salient attribute of the rifle is its inherent reconfigurability; the optics, stock, barrel and firing mechanism are all designed in modular sections to simplify the tailoring of the weapon to specific needs.[7] Other potential components of the weapon include gyro compensators and adaptive texture barrel sheaths.[8][Note 1] One configuration of the weapon, which was deployed during the Battle of Installation 04, featured a noticeably longer barrel and different optic than the configuration observed later during the Battle of Mombasa and the Battle of Installation 05.[3][4] The former version mounted an optic capable of x2 and x8 magnification,[3] and the latter an optic capable of x5 magnification, though both optics were smart-linked and capable of x10 magnification, and both weapons were employed firing APFSDS (armor-piercing fin-stabilized discarding-sabot) ammunition.[2][1]

During Operation: TALON, Linda-058 deployed her SRS99C-S2 AM with an alternate barrel designed to suppress firing report and muzzle-flash and, in order to compensate for the reduced muzzle velocity that came with this, re-chambered it to fire .450-caliber ammunition. Additionally, she removed any sight or scope, instead deeming to rely on an integrated link between the weapon and her HUD for the close-quarters environment. She also brought a supply of extended magazines to last her the engagement.[7] She later employed the weapon in a different configuration during the Battle of Sigma Octanus IV, this time with an Oracle scope.[9]

The appearance of the SRS99C-S2 AM is characteristic of Series 2 iterations of the SRS99 family. While bulky, its body is streamlined and smooth, somewhat simple in design, and possesses a matte-black or grey finish. The charging handle is positioned on the left side of the weapon, a tube-shaped protrusion with a metallic finish, and the ejection port is situated on the right.[Note 2] A square-shaped carry-handle is positioned above and in front of the scope. The configuration used on Installation 04 featured a solid stock joined to the base of the pistol grip, while the later version lacked this, and its stock had a prominent cutout. The barrel is locked into the upper receiver of the weapon by a prominent, rounded collar.[3][4]

Functionality[edit]

As with most human weapons, to fire the SRS99C-S2 AM, the index finger is used to depress a trigger positioned towards the top of the grip. After firing, no additional action is required to chamber another round, with the weapon’s gas systems serving to cycle the bolt, ejecting the spent casing and loading a new round automatically. Holding the trigger down, however, will not result in continuous firing, making it semi-automatic, as opposed to fully-automatic. When the weapon fires, a hot cloud of fiery gas is expelled from the barrel exit and the ports of the muzzle brake, and as the projectile travels through the air, it leaves a lingering trail of smoky vapor. The expended cartridge case is ejected out of the right side of the weapon as the charging handle reciprocates, before moving forward again as the next round is chambered. This process can be repeated continuously until all available rounds are expended.[3][4]

In the case of the configuration used on Installation 04, when the magazine is empty, the charging handle locks back, indicating the functionality of a bolt catch. Once the magazine is exchanged, the charging handle must be nudged to release the bolt into its closed position, stripping a round from the magazine on its pat
