AR-15

A broad term for a sporting and military rifle originally developed by Eugene Stoner while working for the ArmaLite firearms company, a division of Fairchild Aircraft (The patent was later sold to Colt because of financial issues). The original design (released in 1956), was based on the AR-10 in .308, was revolutionary at the time for using a .22 caliber intermediate cartridge, and a semi-direct-impingement . This cartridge offered low recoil and similar terminal ballistics to the larger .308 Winchester (7.62x51mm NATO).

As for the idea that the AR-15 is a dangerous weapon of war designed to kill, and that actually holds some truth. Eugene Stoner originally designed the AR platform for military contracts. However, Stoner designed the AR not for pure killing, but for these traits: Lightness, low recoil, modularity, and ammunition size while still retaining enough wounding potential to get the job done. As for the reason that they are used in mass shootings? First off, most people in America do not know much about guns and are quick to assume that any black "tactical" rifle is an AR (Even if they're not). Secondly? They're the most popular rifle in America. For the same reasons I just listed, the AR is extremely popular here, and is readily available. It's not something to be scared of! Go shoot one, and you might see that.
Eugene Stoner designed the AR-15 primarily for it's weight and not for it's wounding potential.

AR-15

The AR-15 is a hyper deadly fully semi automatic clip loading high capacity bump stock military style assault weapon which utilizes a .50 caliber 30 magazine clip. It can also be modified with deadly attachments like a chainsaw bayonet or the dreaded shoulder thing that goes up. The magazine clip can also be changed to utilize a 9mm bullet which is famous for blowing the lung out of the body.

The AR stands for Assault Rifle and the 15 indicates a power level of 15. Keep in mind that the maximum power level is 10. It is a deadly weapon of mass destruction which would simultaneously be useless against the US Government if they ever became tyrannical because they have drones and tanks. It is far too dangerous for civilians to own as it has been used in every mass shooting ever.

AR-15

AR means armalite not assault rifle but who gives a fuck because if u give one to a kid with depression while hes at school we can all have a great time. Most are semi automatic but i guess u could make one full auto if u really wanted *cough* meet me at my house at 3 *cough* but most ppl dont have the money to fuck around with that. The media also likes to give this gun bad publisity , u know cuz ppl like to bring them to school and play the song "pumed up kicks" while mowing down kindergardeners. But really its just another gun that almost everyone has.
