I'm always happy to elaborate:
Semiauto - short for semiautomatic, is a type of firearm type which is auto loading and fires sequentially with only activation of the trigger, not requiring manual operation of the action.
DBM is an acronym for detachable box magazine, describing a firearm component which containerizes ammunition and supplies the cartridge feed mechanism for the action.
Mini-length is a class of firearms cartridges denoted by their length, for mini-length limited to <2.3". This class of cartridges includes rounds used in the AR-15 and Ruger Mini actions, such as the 223remington/5.56 Nato, 6.5 Grendel, 6.8 SPC, 300 Blackout, 7.62x39...
Carbine is a term referring to a rifle format, generally shorter than a standard rifle.
The AR-15 and the Ruger Mini were derived from firearms designed for military and law enforcement use, and gained their civilian market popularity, in large part, due to their contracted deployment for these uses.
Fuji and Golden Delicious are varieties of Apples, referenced here that sharing ALL of the above classification and design aspects between the AR-15 and the Ruger Mini would explicitly define them as both "Apples," with acknowledgement that they are two distinct varieties among the same species.
How someone can pretend comparison of these two rifles is like comparing "apples and oranges," truly escapes me. Certainly, they've been compared for half a century, including comparison when bidding for law enforcement contracts, and military contracts around the world. We've compared AK's, SKS's, Mini's, AR's, M1 Carbines, and many other semiauto carbines and rifles like SCAR's, Galil's, FAL's, M1A's/M14's, Garands, ACR's, and on and on, for generations... Certainly not apt to say these comparisons are like "apples and oranges."
