History

The 40AGL was made in 1990, followed by the 40LWAGL in 2001 (previously called the 40 mm Super Light Weight AGL).

On 19 June 2000, STK announced the release of an upgrade kit, known as the 40mm Automatic Grenade Launcher Air-Bursting System (40mm AGL-ABS).[3] Upgrades consist of the electronic fire control system, the gun computer, the muzzle programming coil as well as the optical sighting system.[3]

On 13 December 2010, the Kuwait Defense Ministry released a statement that the CIS 40 AGL was offered for the Kuwaiti military.[4]

Design

The 40AGL is mounted in combination with the 12.7-mm 50MG in the ST Kinetics' 40/50 cupola weapon system, installed on the M113 and Bionix. The 40AGL weighs 33 kg without mount or ammunition.  

The STK 40 AGL can be mounted on a M3 tripod, a light weight tripod, a lock/fire mount, softmount, ringmount or on a RWS.[5]

The range of 40 mm rounds include low velocity, high velocity, less-than-lethal, camera,[6] self-destruct, airburst and enhanced blast insensitive explosive rounds.  

Aside from regular 40mm grenades, it can also use Air-Bursting Munition Systems to increase both firepower and lethality.[7]

Variants

Perspective

Mark II

The STK 40 AGL has a Mark II variant, which includes weight reduction of almost 6 kg; a barrel removal system; improved handling, performance, aesthetics and ergonomics.[8] The components, when disassembled, consist of the operating group, barrel, receiver group, top cover group, trigger group.[8]

40LWAGL

Previously called the 40 mm Super Light Weight AGL, the objective of ST Kinetics in designing the 40LWAGL was to keep the grenade launcher's weight to below 20 kg, or half the weight of conventional AGLs.

3GL

In 2008, ST Kinetics entered into a teaming agreement with Electro-Optic Systems (EOS) and Metal Storm (MS) to develop a 3-shot under-barrel grenade launcher called the 3GL.

The 3GL is intended to replace the M203 under barrel grenade launcher for most military rifles including the M16, AK-47, SAR 21 and Steyr AUG. It can also be detached to operate as a stand-alone weapon.[9]

The 3GL is a semi-automatic grenade launcher firing individually loaded grenades, with up to three rounds being able to be loaded and fired semi-automatically. It can be attached to weapons via RIS rails or to a stand-alone folding stock.[10]

Redback Lightweight

St Kinetics also collaborated with Australia's Metal Storm and Electro Optics System to develop a new high-speed and recoilless 40 mm grenade launcher.[11]

Notes

  1. Using the Wayback machine on this CIS 40 AGL page indicates that the CIS 40 AGL name was used until early 2017, when it changed to the STK 40 AGL name as seen here.
