Good news! There is no such thing as an "assault riffle". :)

And a shotgun doesn't involve a shotgun...

Characteristics[edit]
The U.S. Army defines assault rifles as "short, compact, selective-fire weapons that fire a cartridge intermediate in power between submachine gun and rifle cartridges."[16] In a strict definition, a firearm must have at least the following characteristics to be considered an assault rifle:[2][3][4]

• It must be capable of selective fire.
• It must have an intermediate-power cartridge: more power than a pistol but less than a standard rifle or battle rifle, such as the 7.92×33mm Kurz, the 7.62x39mm and the 5.56x45mm NATO.
• Its ammunition must be supplied from a detachable box magazine.[5]
• It must have an effective range of at least 300 metres (330 yards).

Rifles that meet most of these criteria, but not all, are technically not assault rifles, despite frequently being called such.

For example:

• Select-fire M2 Carbines are not assault rifles; their effective range is only 200 yards.[17]
• Select-fire rifles such as the FN FAL battle rifle are not assault rifles; they fire full-powered rifle cartridges.
• Semi-automatic-only rifles like the Colt AR-15 are not assault rifles; they do not have select-fire capabilities.
• Semi-automatic-only rifles with fixed magazines like the SKS are not assault rifles; they do not have detachable box magazines and are not capable of automatic fire.
