A bayonet lug is a standard feature on most military and on some civilian longarms. It is intended for attaching a bayonet, which is typically a short bladed multipurpose knife bayonet. The bayonet lug is the metal mount that either locks the bayonet onto the weapon or provides a base for the bayonet to rest against, so that when a bayonet cut or thrust is made, the bayonet does not move or slip backwards.
