The AR-15 is the civilian equivalent of the M16 (and M4) rifle used by the United States armed forces. It is by far the most popular
modern sporting rifle in the world, and for good reason - it is lightweight, very accurate, and super reliable. It is an exceptional
rifle for hunting, target shooting, competition, and home defense.
