(Ladder Sight: 155g) (Saddle Sight: 85g) The Milkor 40mm UBGL grenade launcher is a lightweight single-shot, underslung grenade launcher designed and developed in South Africa by Milkor (Pty) Ltd.[1] It can be attached to most modern assault weapons and rifles using a Picatinny rail system.
The UBGL is fitted with a steel barrel with constant-pitch rifling and swings to the side for loading and unloading of standard low-velocity 40mm cartridges.
This enables the user to have a 40 mm grenade launcher capability together with an assault rifle.
The UBGL can also be fired independently from a rifle (handheld) in an emergency.
[5] The opening mechanism swings to the side in order to enable the user to load ammunition without external interference of the weapon it is mounted to or other complications.
