The 40 mm Under Barrel Grenade Launcher, is a single shot grenade launcher developed by ARDE and Ordnance Factory Tiruchirappalli[1] for use with the INSAS and AK-47 rifles used by the Indian Army. Stand alone versions of the grenade launcher exist.[2]

Design[]

The 40mm UBGL can be attached to Indian INSAS and AK-47 rifles, and has a 3-point attachment for rigidity. The UBGL has an in-built safety to prevent accidental firing. The trigger system is located on the side of the barrel, allowing the soldier to fire both the rifle and grenade launcher without having to change his firing posture.[2]

The weapon uses a simple ladder sight mechanism, similar to the GP-25. It also has tritium illuminated sights for night firing. The ammunition fired by the UBGL, is similar to the Milkor MGL used by the Indian Army, allowing for standardisation.[2]
