Equipment (Weapons)/Melee Weapons

When mounted on a rifle, a bayonet allows you to use the rifle as a melee weapon much like a spear. When wielding a rifle with a mounted bayonet, you threaten squares within your reach (even if you used the rifle to make a ranged attack on your last turn), and you can use it to make attacks of opportunity. A bayonet requires two hands to use when mounted on a rifle.

A bayonet cannot be used on a rifle with a folded stock. A bayonet detached from a rifle is treated as a knife; a mounted bayonet deals more damage than the knife because of the added leverage and bulk.
