Frequently Asked Questions — AR Rifles
What does AR stand for in AR-15?
AR stands for ArmaLite Rifle — the company that designed the platform in the 1950s. It does not stand for "assault rifle" or "automatic rifle." The AR-15 is a semi-automatic rifle that fires one round per trigger pull. It was designed by Eugene Stoner and adopted by the U.S. military as the M16 in 1964. Civilian AR-15s have been commercially available since the 1960s.
What caliber does an AR-15 use?
The standard AR-15 chambering is 5.56 NATO or .223 Remington — they are nearly identical and most AR-15s fire both. The platform is also available in .300 Blackout (suppressed/short barrel optimized), 6.5 Grendel (extended range), 6.8 SPC, 7.62x39 (AK caliber), .350 Legend, and more. AR-10 pattern rifles chamber larger calibers including .308 Winchester, 6.5 Creedmoor, and .300 Win Mag.
What is the best AR-15 for a beginner?
For a first AR-15, the Smith & Wesson M&P15 Sport II, Springfield Armory Saint, and Ruger AR-556 are the most recommended options — reliable, accurate, and priced accessibly. Mid-range options from Aero Precision, Radical Firearms, and Palmetto State Armory offer excellent value. Once your budget allows, Daniel Defense, Bravo Company (BCM), and LWRC represent the premium tier.
Is an AR-15 legal to own?
AR-15 rifles are legal for civilian ownership in most U.S. states. Some states including California, New York, New Jersey, Massachusetts, Connecticut, Hawaii, and Maryland have restrictions on specific features like pistol grips, adjustable stocks, or flash hiders. Always check your state and local laws before purchasing. All AR-15 purchases require standard FFL transfer and background check.
What is the difference between AR-15 and AR-10?
The AR-15 is the smaller platform chambered in 5.56 NATO/.223 Rem and similar calibers. The AR-10 is the larger platform chambered in .308 Winchester, 6.5 Creedmoor, and similar larger calibers. AR-10 rifles are heavier, have more recoil, and cost more than AR-15s, but offer greater effective range and terminal performance. Parts and magazines are not interchangeable between the two platforms.
