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.

Background
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.

Trivia

 * As of the 21st century, the term "APFSDS" is reserved for large tank-mounted weapons. For smaller munitions such as the Sniper Rifles of the Halo series, it is called a Flechette.
 * In-game, the scope shows the identity of its user, SPARTAN-B312, as "ID-NOBLE6," regardless of whoever wields it. There is also a small UNSC logo on the left of the scope.
 * In the Mission Nightfall, the player is given 50 Rounds instead of 20.
 * Although it appears the weapon has no gameplay effect from reticle bloom, it actually does by a miniscule amount. This can be proven by enabling the "Bottomless Clip" option in gametype settings and firing the rifle as fast as possible. Gradually, the bloom will expand and shots will become inaccurate.
