SRS99-S5 AM sniper rifle

The Sniper Rifle System 99-Series 5 Anti-Matériel, abbreviated SRS99-S5 AM, is a gas-operated anti-material sniper rifle used by the United Nations Space Command. The S5 model was designed and manufactured by Misriah Armory.

Design details
The SRS99-S5 AM is a semi-automatic, gas-operated sniper rifle that fires 14.5mm x 114mm APFSDS rounds from a 4-round magazine. It is, alongside its primary Covenant counterpart, the Type-27 Special Application Sniper Rifle, the most accurate and arguably the most powerful small-arms weapon in either arsenal.

It is a successor to the S2 variants used throughout the Human-Covenant War by the UNSC Navy and Marine Corps. The S5 model incorporates many features seen on the older SRS99 rifle used in large numbers by the Army.
