AR-15

Semiautomatic version of the M-16 used by the United States military, legal for civilian ownership in most states thereof. Uses the .223/5.56 NATO round. Like the M-16, it's accurate but not very reliable because of its direct gas impingement system.
My buddy got killed by home invaders because his AR-15 jammed. He should have bought an AK or FAL.

AR-15

An overrated plinker owned by far too many people, mostly trendy try-hards, that must be broken down and cleaned more often than the AK to keep it running reliably and is more complicated and tedious to break down and clean than the AK to boot. In return for this trouble you'll get an extra MOA of accuracy that you'll never need in a real world combat or personal defense situation
The AR-15 is a fun toy but when they SHTF, I am reaching for my AK-74.

The AR-15, short for Assault Rifle, is a lightweight, magazine fed, .223 caliber, automatic rifle. Can tear anybody to pieces in seconds. A favorite or Pastor Troy.

AR-15

The (somehow completely legal) firearm of choice for mass shootings in the US, this firearm not only can fire many different sizes of ammunition, but ultimately results in the thoughts and prayers of members of the US government.
“There was yet another mass-shooting that involved and AR-15. Now we get to listen to NRA activists condescendingly shit on everyone about how the “AR” stands for “ArmaLite”, not “Assault Rifle”, instead of talking about the actual problem.
