Ar15 upper receivers were designed by George A. Smith and first produced in the early 1960s. At that time, these rifles were used by law enforcement and paramilitary organizations throughout the United States. The rifle was originally designed as a compromise between military-style design and a civilian-friendly package. As such, it featured a number of features that would later be adopted by other firearms designs. Some of the first Ar15 rifles were manufactured in Mount Prospect, Illinois, which is now home to the company’s headquarters. This city was once known for its manufacturing capabilities within the firearms industry and consequently has a long history with firearms ownership and production. Ar15 rifles have been used in various conflicts around the world, most notably during World War II when they became popular among American forces stationed abroad. Theseguns continue to be used today by many different organizations both domestically and abroad. In addition to their use within law enforcement and paramilitary groups, Ar15 rifles are also popular among hunters and recreational shooters across all demographics.

Ar15 upper receivers come in a variety of configurations and materials. They can be made from aluminum or black anodized aluminium, with or without a Picatinny rail. Some models have a muzzle brake, others do not. Many models also include a battery and flash hider. There are two main types of ar15 Upper Receivers: those that use the bolt carrier group (BCG) as their goalpost, and those that don’t. The BCG is what sits in front of the rifle's action and controls how many rounds per magazine it can fire before needing to be reloaded. The type of receiver you choose will largely depend on your specific needs such as weight and accuracy, although some features common to all receivers include 3-Position buffer tube catch lever system, 30+1 feedramps (for feeding multiple rounds at once through the same mag), forward assist and dust cover options.
