The "Grenade Gun" found on the M16 rifle is called the M203 grenade launcher. It is used by manually opening the loading port, inserting a 40mm grenade, closing the port, and depressing a separate trigger. The M203 will then discharge its grenade at the intended target. Further detail is not (in my opinion) necessary for this answer.

The US military's primary infantry weapon for training is the M16. Just remember that when you enter bootcamp that you dont call the M16 your "gun".. The M16 is your "weapon"
The M16 and the M4 are the US designations for the AR-15 pattern of rifles.
