what's your class?
If your class doesn't have machine gun training, you can just add any desired weapon to your class, just remember not to have over 4 weapons.
And if you have the light machine gun training, then you could just edit it.
Link the 3rd post teaches you how to add weapon, the 8th teaches you how to add weapon training
