The STK 40 AGL, formerly the CIS 40 AGL[lower-alpha 1] is a 40 mm automatic grenade launcher, developed in the late 1980s and produced by the Singaporean defence firm Chartered Industries of Singapore (CIS, now ST Kinetics). The launcher is employed primarily by the Singapore Armed Forces and the police and security forces of several other countries.[1]

History

On June 19, 2000, STK announced the release of an upgrade kit, known as the 40mm Automatic Grenade Launcher Air-Bursting System (40mm AGL-ABS).[2] Upgrades consist of the electronic fire control system, the gun computer, the muzzle programming coil as well as the optical sighting system.[2]

On December 13, 2010, the Kuwait Defense Ministry released a statement that the CIS 40 AGL was offered for the Kuwaiti military.[3]

Design

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.[4]

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.[5] The components, when disassembled, consist of the operating group, barrel, receiver group, top cover group, trigger group.[5]
