Combat Rifle

The Combat Rifle (or SCAR-L) is an automatic weapon that has a capacity of 60 rounds per magazine. Unlike the other assault rifles, it fires a three-round burst every time the fire key is pressed. It is suspected that this will be a tier 2 weapon.

It seems that Valve has change the reloading mechanics once the user empties the whole clip. You now have to cock the hop up, then detatch the magazine, then put another in, and pressing a button that releases the hop up.
