Wilcox Unveils MINI-GL40 Modular 40mm Grenade Fire Control System

Wilcox Industries has announced the MINI-GL40, a standalone 40mm grenade launcher platform built around the company’s RAAM GSS M fire control system. The system was released on May 14 and is aimed at modern grenadiers who need a day and night capable, modular platform with integrated ballistic computation.

The MINI-GL40 is built around a steel-lined barrel engineered to withstand repeated firing of all low-velocity 40mm rounds, including breaching loads. Wilcox says the steel liner reduces wear compared to legacy systems and ensures long-term reliability under sustained use.

The integrated RAAM GSS M fire control system is what sets the MINI-GL40 apart from a traditional standalone launcher. The operator selects ammunition type, inputs range, and the system generates an instant firing solution with automatic POA/POI adjustment. Integrated sensors and onboard processing reduce engagement time and increase first-round effectiveness. The system runs on a single AA battery and includes two pre-programmed ballistic solutions.

Beyond the ballistic computer, the launcher consolidates optics, lasers, illumination, and fire control into one platform. Features include a co-aligned optical bench, a red dot sight with backup iron sights, a near-infrared aiming laser, and a near-infrared illuminator. Ergonomics are improved with ambidextrous controls and an enlarged breech lock lever. The stock is adjustable, collapsible, and folding.

The MINI-GL40 is waterproof to one meter for 30 minutes and is compatible with a quick-draw leg holster. It fires any length low-velocity 40mm round, which covers the standard high explosive, smoke, buckshot, and less-lethal options.

Wilcox has spent years developing fire control systems for grenade launchers, including its collaboration with the U.S. Army on the GSS program for the M320. The MINI-GL40 represents the company’s effort to package that expertise into a standalone weapon rather than an under-barrel or clip-on accessory.
