This article is about the sniper rifle in Halo 2. For other sniper rifles, see sniper rifle.

The Sniper Rifle System 99C-Series 2 Anti-Matériel B (abbreviated to SRS99C-S2 AMB), otherwise known as the SRS99C-S2 AMB Sniper Rifle is an anti-matériel/personnel rifle in use by the United Nations Space Command.[1] It saw widespread use during the Battle of Earth and the Battle of Installation 05.[2][3][4][5]

Design Details Edit

The SRS99C-S2 AMB is a semi-automatic UNSC sniper rifle that fires 14.5mm x 114mm APFSDS (Armor-Piercing Fin-Stabilized Discarding Sabot) rounds from a 4 round magazine. It is designed in the conventional layout, so the mag and operating system are located in front of the trigger.

This powerful weapon is gas-operated and therefore must be cocked to load the first round. Once the first round is fired, the gases from the previous round forces the bolt back and forth and continues to do so until the mag is empty. Once the mag is empty, the bolt (although not illustrated in-game) locks back. After a new mag is inserted, the bolt must be pushed forward to chamber a new round. The bolt used to chamber the round is located on the left side of the weapon and moves during operation. The ejection port is located on the right side of the weapon and possesses a dirt cover.

It features a barrel about 168.5 cm long and is completely interchangeable. From the barrel to the breech to the stock, everything can be changed to fit the current situation and satisfy the operator. The SRS99C-S2AMB has some notable changes from the AM model. First off, it is fitted with a 5x and 10x scope that shows real time images. When looking through it, the scope (Oracle N-variant) seems to be down-graded considering the AM model's scope showed the target's elevation and distance and showed when the scope was leveled. The AMB also has an altered foregrip and stock as well as an altered body. This weapon does not possess a safety and has a frame that serves as a carrying handle as well as a scope protector. A folding bipod is located in front of the magazine on the underside of the gun.

The AMB offers an electronic scope which provides both 5x and 10x magnification. While looking through the scope without engaging the electronic magnification, a real-time image is seen. The "green radar" effect of the AM variant, as well as the night vision function, have been removed.


The SRS99C-S2 AMB Sniper Rifle fires the 14.5x114mm APFSDS (Armor-Piercing Fin-Stabilized Discarding Sabot) rounds semi-automatically from a four round magazine. Each shot leaves a vapor trail behind it for a few seconds after it is fired. Each shot has an extremely high damage rate, and a head-shot is usually a one hit kill. Also if used correctly the SRS99C-S2 AMBs high-velocity rounds can have extreme effectiveness against vehicles, though this is not shown in the games. 

This section requires expansion.


The sniper rifle appears to be heavily inspired by the Barrett .50 caliber rifles (most notably the M82 and the M107 sniper rifles), and the South African NTW-20. Many of the features present in the Halo version are included in both weapons, such as the recoil-dampening piston, the general look of the receiver, the magazine placement, muzzle brake, and many other attributes. In addition, the Sniper bullet (14.5 × 114mm) is an actual rifle cartridge, developed by the Russian Army for Anti-Tank Rifles, Heavy Machine Guns, and Sniper Rifles. However, the real 14.5 mm round has a standard cartridge design, whereas the round used in Halo is an APFSDS round (Armor-Piercing, Fin-Stabilized, Discarding Sabot).


  • It was first mentioned in Halo: Ghosts of Onyx, when Petty Officer Second Class Linda-058 used it at Havana during the Battle of Earth and later during the Battle of Onyx. Because of the features she stated, it was clear that the SRS99C S2-AM used in Halo 2 is the AMB model.
  • Currently the term "APFSDS" is reserved for large Tank mounted weapons.
  • The bipod on the SRS99C is only seen being used once, in the opening cutscene to the level Outskirts in Halo 2. It is only seen briefly for about 5 seconds (0:34 - 0:39) in the cutscene being used by a marine scout positioned on a rooftop along with his spotter. The bipod is not extended due to only one set model of the sniper rifle in the game, but is still being used to support the rifle on a cinder block.
