Well I cracked at the Cybermonday sale and jumped on the wagon.
Still feels a bit risky, but what the hey I've got other

Check your terms. You have assault rifle confused with assault weapon. They are not interchangeable.
Assault Rifle is loosely translated from the WWII German sturmgewehr aka STG or MP44 etc etc. Hitler himself coined the term. In practice it refers to a rifle or carbine sized firearm that fires an intermediate sized cartridge (that means smaller than a rifle round but larger than a pistol round) that is (this is the big one) capable of select fire. Select fire meaning the operator can switch between semi automatic or full auto/burst.
Most modern and contemporary military rifles conform to this definition including the M16 and Ak47.
Assault Weapon by comparison was an artificial term developed by politicians that typically appears to be an assault rifle but is usually just semi automatic. Of course the term is also thrown around very loosely by the media and politicians to mean anything that looks scary. This term is largely considered offensive in the firearms community because of its negative political connotations, in addition to it largely referring to aesthetic features of a firearm, not functional ones.
Assault Weapon may have a legal definition depending on which state you live in. It has not had any Federal meaning for about a decade now.
