In the lobby of any Multiplayer match, you can instantly jump into the Virtual Firing Range. This firing range allows you to quickly test any weapon combination you want. Try out different attachments to get a feel for handling, recoil, sights, and so on.
Inside the Virtual Firing Range, you can step into several different firing lanes. Each one creates a different target array, instantly creating unique terrain, cover, and targets against which you can test your weapons.
