Wilcox Industries – US Army’s Grenadier Sighting System
The Grenadier Sighting System for the M320A1 Grenade Launcher Module is one of the most successful programs of the past few years and one of the least publicized.
Assigned NSN: 1010-01-686-8798, GSS provides the capability to accurately engage targets day and night with the M320 GLM. The GSS features include a reflex optical sight with integral back up iron sights, near infrared (NIR) aiming laser engagement for night engagements, NIR illuminator for increased detection and recognition at night, user selectable ballistic solution for up to 16 ammunition types, including quick selector for two pre-programmed ballistic solutions, atmospheric temperature and pressure sensors for ballistic compensation, and a cant indicator for increased accuracy when firing. Wilcox makes similar commercial version alternatives designated by the company as the Rapid Acquisition Aiming Module Grenadier Sighting System (RAAM GSS). The Wilcox RAAM GSS is an exportable version of the US Army selected and current production Grenadier Sighting System.
Manufacturer Wilcox Industries has created a three part series on the GSS. In Part 1 & Part 2, Wilcox covered the US Army’s search for a new 40mm M320 GL in 2009, their decision to choose theWilcox GSS as the single production awardee in June 2019 and the GSS’s initial production and discriminating features.
“The GSS is a significant improvement to the M320 and tremendously increases the Grenadier’s capability in all environments.”
