Eugene Stoner and the ArmaLite AR-10.

In 1954, Fairchild Engine and Aircraft Corporation founded the ArmaLite division of its company to focus on designing guns in hopes it would lead to military and government contracts. ArmaLite hired Marine veteran and firearms designer Eugene Stoner as Chief Engineer. Stoner’s big idea at the time was to use advanced plastics and lightweight aluminum alloys to build a gun—a revolutionary idea at the time. ArmaLite’s first firearm was the AR-5 survival rifle. Called the MA-1 in the U.S. Airforce, the bolt-action AR-5 was chambered in .22 Hornet, came apart for compact storage and floated.

The Army began its search to replace the M1 Garand in 1955. Stoner submitted his .308 AR-10 which had a lightweight aluminum receiver and a plastic stock and handguard. He used a steel barrel extension to lock the bolt. They didn’t make the deadline, but the Army asked ArmaLite to design a rifle like the AR-10 but in a smaller caliber—which later became the AR-15. The military version of the AR-15, called the M16, was licensed to Colt Firearms in 1959.

After the patents for the AR-15 design expired, Jim Glazier and Karl Lewis of Lewis Machine and Tool started making their own civilian AR in 1989. Today’s AR-15 is a semiautomatic rifle either gas- or piston-operated and fires from a locked bolt. Traditionally it is chambered for .223 Remington/5.56mm NATO but AR-style rifles are chambered in many different calibers including pistol calibers like 9mm and .22 LR. Most find the AR-15 easy to operate and manage. It is a highly customizable rifle, which is a huge part of its appeal.

Today, the AR-15 is considered America’s favorite rifle. The National Shooting Sports Foundation estimates there are anywhere between 5 to 10 million AR-15s owned in the U.S.A.

The AR-15 is easily built from the bottom up with the purchase of a lower receiver, which is the part of the gun with a serial number and the part the government deems the “gun” part of the gun. When building and accessorizing an AR, it may feel like there are an endless amount of choices of parts—and there almost is! AR parts and accessories are available in all different budgets from the high-end and hand-tuned one-of-a-kind pieces to assembly line, made in China cheapies.

When it comes to AR accessories and parts, the higher price doesn’t necessarily reflect higher quality. One of the most trusted companies, Magpul, that make magazines, stocks and grips for the AR is also very affordable. For the everyday shooter—meaning someone who doesn’t use their gun for their job—and casual hunter, even some of the cheapest AR accessories stand up to the test. That’s one of the reasons why the AR-15 is so awesome—you can build one on a strict budget that will hit targets accurately and take down hogs, varmints, pests and predators.

You can run an AR accurately without any bells and whistles but what’s the fun in that, especially when there are a plethora of accessories that will enhance your shooting? Stocks, furniture, grips, handguards and rails, and optics are all parts AR owners love to mount on their rifles for something unique to them.

If new to the black rifle world, you probably are wondering where to begin. You will obviously want a lower receiver, upper receiver, lower parts kit with bolt carrier group (BCG) and barrel. These are the parts necessary to make the gun fire. Once you get those essential parts, you can start building!

After choosing the ‘gun’ parts of your gun, you’ll want to consider its primary use. Many accessories are designed for a specific purpose. For example, reflex sights for competition, flashlights for home defense, long-range riflescopes for precision shooting, suppressors for noise and so on.
