ARMALITE AR 15 RIFLE - THEN AND NOW
The story of AR15 began in 1956 when ArmaLite Inc started producing selective fire rifle for military use called ArmaLite model 15. Due to financial problems and bad decisions, ArmaLite sold the patent to Colt Manufacturing Company in 1959.
In 1963, the U.S. military chose Colt to manufacture the automatic rifle that soon became the standard gear part of the U.S. Army. The AR 15 became M 16. When Colt's patents for the AR-15 expired in the 1970s, other manufacturers entered the business. They started producing the rifle under different names. The popularity of the AR-15 turned those names into a generic term for all types of AR-15-style rifles.

Today, the AR-15 is one of the most customizable weapon platforms on the market. In fact, many people say the best AR 15 is the one you build yourself, even if it's just using a build kit (though we've helped many, many people choose a complete AR 15).
• Want to change up your complete rifle with a different barrel length? That's an easy fix.
• Want to change that stainless steel barrel for one with black nitride? It won't be inexpensive to do so.
• Looking to suppress it and want a silencer-friendly bolt carrier group? Switch it in seconds.
• Want a rifle scope to augment your iron sights - or alternate (BUIS) sights? Too easy.
• Prefer one rifle with many purposes? Start with an AR 15 lower, then add an accessorized upper receiver for each intended task. That gives you a complete rifle for each “mission” without having to buy more than one complete lower.
• Like the way a certain handguard looks, or how it's laid out? Pop it on there.
• Want to try an adjustable gas block? We got you.
It's not just basic rifle parts and individual items, either. Pre-specced AR 15 rifle kit options allow you to adjust your rifle depending on your need. That may be limited to a specific niche item, end-use-focused accessories, or a rifle kit with your preferred rifle furniture. New products from innovative companies are coming out every day. The possibilities for your rifle are nearly endless.
