XM131

The XM131 is a military weapon platform developed by the United States military, primarily designed to enhance small arms firepower. It is a lightweight, modular automatic grenade launcher chambered for 40mm grenades, offering increased firepower and versatility compared to traditional grenade launchers. The XM131 is part of the broader family of crew-served weapons used to support infantry units by engaging targets at medium ranges.

Designed for both stability and mobility, the XM131 can be deployed on a variety of mounts, including vehicle installations and bipods, allowing flexible use in different combat scenarios. Its operational mechanism is semi-automatic, enabling rapid firing sequences with high accuracy, supported by an integrated sighting system. The launcher employs a quick-change barrel system to facilitate rapid reloading and cooling during sustained operations.

The weapon's construction emphasizes durability and lightweight materials, making it suitable for airborne, mechanized, and dismounted infantry units. Its fire rate varies, typically ranging from 200 to 300 rounds per minute, depending on operational settings and ammunition type. The 40mm grenades used by the XM131 are capable of delivering high-explosive, smoket, or illumination effects, providing tactical options for various combat needs.

The XM131 has undergone several rounds of testing and evaluation since its inception, with the goal of replacing older grenade launch systems. However, its adoption into widespread service has been limited, often as part of specialized units or prototypes for future integration in combat scenarios. Its development reflects ongoing efforts to improve infantry support weapon systems through lightweight, flexible, and high-volume fire capabilities.
