- "An AR-15 converted to a .50 caliber upper reciever. Its high caliber results in effective damage and incredible stopping power."
— In-game description
The .50 Beowulf calibre used is a proprietary calibre designed by Bill Alexander of Alexander Arms. The round itself is intended to improve stopping power at short-to-medium ranges compared to the standard 5.56×45mm NATO.
In-game, designated as the AR-15.50, this rifle is functionally a marksman rifle, having the ability to kill in two shots at its optimum distance.
- The AR-15.50 appears to use quad-stacked magazines. Despite this, it incorrectly holds 10 rounds.
- In the Main Menu Interface for the Grim Sky season, Maverick is equipped with the AR-15.50, which itself is equipped with a Holographic Sight and a Vertical Grip.
