SRS99-AM sniper rifle

The Sniper Rifle System 99 Anti-Matériel, more formally known as the Special Applications Rifle, Caliber 14.5 mm, SRS99, is a United Nations Space Command sniper rifle. The SRS99 first entered service with the Army in 2460. Because of its modularity and ongoing manufacturer support, the SRS99 was adopted by all branches in 2521.

Design details
The SRS99 is a semi-automatic, gas-operated rifle that fires 14.5x114mm ammunition from a four-round detachable box magazine. The ejection port is on the right side of the weapon and the charging handle is on the left side. Unlike all other known models of the SRS99 series, this variant features a thumbhole stock instead of a pistol grip, and its body sports a black and navy blue finish in addition to the gray of its successors. Also unlike its successors, it can be seen utilizing a sling-mount in-game. The SRS99's scope is similar to the SRS99D-S2 AM's scope, as both display green outlines of objects.

Changes from the SRS99D-S2 AM (Halo 3)

 * Increased damage against vehicles, destroying them with four to six rounds.
 * Has a thumbhole stock rather than a pistol grip.
 * More detailed appearance.
 * Updated colors.
 * Scope is smaller compared to the rest of the rifle.
 * Can neutralize a Scorpion tank in two shots, one to destroy the canopy, and a headshot to kill the now-exposed driver.

Trivia

 * In the Halo: Reach Multiplayer Beta, the scope shows the identity of the weapon's user as "ID-NOBLE6", regardless of who wields it. This has been removed in the final build.
 * At the beginning of the level Nightfall, the player receives fifty rounds instead of the default maximum of twenty. This is a tribute to the level The Truth and Reconciliation from Halo: Combat Evolved, in which the player begins with a larger-than-normal number of sniper rifle rounds.
 * The weapon's reticle bloom has almost no effect on gameplay. However, its accuracy is not 100% perfect due to bloom. This can be proven by enabling the Bottomless Clip option in gametype settings, then firing the rifle as fast as possible. Eventually, the reticle will be fully expanded, proving that each shot is very slightly skewed.
