IWI will be debuting their new 40x46mm GL 40S Grenade Launcher at upcoming Eurosatory ’12 expo. It is a standard single shot grenade launcher that integrates well with the Tavor. It is side opening and so accommodates longer 40mm rounds.
From the press release …
Developed in cooperation with the Israel Defense Forces (IDF), the IWI GL 40 Grenade Launcher – which weighs only 1.400 kg – is a single-shot 40x46mm launcher, ergonomically designed, versatile, and compatible with all types of assault rifles. Available in two barrel lengths – for 400m and 300m range – the GL 40 is designed for low and medium velocity (longer than usual range) rounds. Unlimited feed for most 40mm rounds enables operation in any situation or combat conditions. The stand-alone option enables firing separately from the launcher when it is dismantled from the weapon.
Attaching to the lower rail of the weapon and locking rapidly with the lever, the GL40 can be quickly assembled and disassembled by a single soldier without any additional tools. Due to its side-opening barrel, which allows a simple injection and extraction of the grenade, it can use various lengths of ammunition including long grenades. Picatinny rails on the bottom and sides enable the incorporation of various devices and accessories.
