What is an AR-15?
The AR-15 was originally made for a 5.56 NATO cartridge developed for the US Armed forces as a lighter more mobile rifle than the M14 in 7.62x51 NATO. It was first designed by Eugene Stoner, an American mechanical engineer. The AR-15 is a lightweight direct impingement rifle making it a low recoil rifle that is easy to shoot accurately over long distances. The select fire version was adopted by the military as the M-16.
The original manufacturer of the AR-15 was ArmaLite, Inc., with “AR” standing for ArmaLite Rifle. In 1959 Colt purchased the “AR-15” trademark from ArmaLite and in January of 1964 started selling the semi-auto version the Colt AR-15 SP-1 to the public.
Many are misled to believe that the AR stands for Assault rifle which is not the case. Colt termed the civilian version right at the beginning with “SP-1” as in Sporter Rifle 1.” They later offered different models like the Colt Sporter Match Target” and Sporter Lightweight and Sporter Competition model just to name a few.
In 1988 the intellectual property rights expired allowing other manufacturers to make AR-15-style rifles (clones). A better term for AR15 style rifles would be MSR as in Modern Sporting Rifle. Even though essentially the same rifle the only true AR-15s are made by Colt with the AR-15 roll mark. Every brand has its own model name for its AR15-style rifle based on the Stoner Design.
This opened the door for the development of commercial parts and accessories and different cartridges such as 6.5 Grendel, 6.5SPC, 300 Blackout, 458 SOCOM, and more. It is the most popular rifle in America. It is widely used for competition, law enforcement, hunting, and defense.
Why is the AR15 so Popular?
There are several reasons why the AR15/MSR is so popular. One reason is that the AR15 style rifle is easy to assemble and disassemble with only a few specialty tools like a barrel nut wrench and receiver block and some common tools like a bench vice, wrenches and some roll pin punches. Because they are so easy to work on, they became very popular to customize and accessorize. Just about anyone with the tools and some tutorials can build or customize an MSR from an entry-level rifle, hunting rifle, or a competition winner.
The smaller size cartridge vs. high power cartridges made the AR15 affordable as a target practice rifle and its performance abilities made it very popular with pro shooters, varmint hunters, law enforcement, and home defense not to mention they are just a whole lot of fun to shoot.
Manufacturers began making the “flat top” version of the AR15 style rifles with a Picatinny rail on top of the upper receiver instead of the carry handle which led to a whole lot of optic mounting possibilities. Warne was one of the first companies to develop a scope mount for flat-top Picatinny rail upper receivers.
