M1A1 Carbine

The M1 Carbine is an American semi-automatic rifle featured in two Zombies maps in Call of Duty: World at War and the same two revamped World at War maps in Call of Duty: Black Ops.

Overview
The M1 Carbine can be bought off the wall, obtained from the Mystery Box, and from Console Commands. It possesses moderate power, a variable rate of fire, decent accuracy, and low recoil. It can be used up to about round 10, if going for headshots, where its power will start to unaffect the zombies. Also, it's small iron sights may drive players to get another weapon.

Pack-a-Punched Variant
The Pack-a-Punched M1 Carbine becomes the "Widdershins RC-1," obtaining more ammo and a full-auto upgrade. This makes it good for taking out zombies in straight lines, however, does not improve much. It can be used for another five rounds or so, where it becomes useless, almost.
