Damage is 200/50, with a range of 6.5 meters/6.51 meters. There is a .83 second delay between trigger and explosion. Ensure the lasers point towards the intended direction of enemy entry.

The Undermounted Grenade Launcher (UGL) is an attachment for Assault Rifles, such as the M203 (for most Assault Rifles) and the GP-25 (for the AK-47). It fires 40 mm grenades. It has a small area of unavoidable damage and a larger area of splash damage. Damage is 155/25/135 Direct Impact, with a range of 3 meters/9 meters.

Damage is 160/30/1000 Direct Impact. The range is 6.5 meters/6.51 meters/Direct Impact. It has an instant explosion on impact with anything. Do not use this weapon at close range to avoid self-inflicted explosions.
