It entered service with the US military in 1964. The rifle has been used by many different armies around the world, and continues to be one of the most popular firearms in use today. The AR15 upper receiver is a three-piece design made from aluminum, steel, and plastic.

Some of the more common features include: railed handguards, Picatinny rails on top of each barrel nut, flash hider attachments (for greater accuracy), and sling swivels. AR15 rifles are often used by hunters and target shooters who need a low-cost weapon that can provide superior performance at a fraction of the cost of other types of guns. While they are not as commonly encountered as handguns or shotguns, AR15 rifles continue to be very popular due to their durability and versatility

The first successful AR15 upper receiver was created in Santa Barbara, California in 1986. The company that manufactured these receivers is now known as BCM.

Santa Barbara, California is a city located in the U.S. state of California and the county seat of Santa Barbara County. As of the 2010 Census, its population was 269,829. The city is known for its Mediterranean-style architecture and its access to both the Pacific Ocean and Santa Catalina Island. The area that now makes up Santa Barbara was first inhabited by indigenous people who built villages on Point Conception and other nearby hills. Spain claimed it as part of Alta California in 1769 during the Mexican–American War, but it remained a part of Mexico until 1821 when it became Californias tenth state. The name "Santa Barbara" originated with Spanish sailors who called it Isla de la Barra (Island of the Bearded Woman), because he had been told that one such woman was found there by a sailor named Barbareschi. In 1835, gold was discovered near what is now downtown Santa Barbara and rapid population growth made Santa Barbara an incorporated city in 1855. In 1866, parts of what are now Downtown Santa Barbara were included in City Park; this allowed for annexation by Ventura County which then gave rise to Incorporated Ventura County on February 15, 1893 from portions of San Bernardino County which had also become annexed into City Park earlier that year In 1911, many people in Southern California were displaced by smoke created from World War I munitions production in Northern California's San Joaquin Valley The resulting dust storms killed over 200 people across Southern California between 1915-1916

Ar15 upper receivers have been in use for more than 40 years now. They are a favorite choice for many shooters because of their high quality and durability. The ar15 family of rifles is composed of several different models, each with its own unique features and benefits. The first ar15 rifle was designed by George Weger in the early 1960s. It was called the A2B Rifle and it featured a select-fire action that allowed users to change the ammunition that they fired from stock to full-auto. This rifle was especially popular among police officers and other law enforcement professionals who needed an easy way to fire hundreds or even thousands of rounds per minute without having to worry about reloading. In the late 1960s, a new design called the A3M Rifle was released. This model featured a gas-operated action that allowed users to change calibers (7mm, .308 Winchester, etc.) without needing to remove the magazine or disassemble the rifle. This model quickly became popular among hunters and competitors due to its easy adaptationability and ability to shoot multiple types of ammunition at once. In recent years, there has been a trend towards using alternative barrel designs ( nicknamed “A3X” or “AR-X”) on ar 15 upper receivers. These barrels feature advanced technology that makes them much stronger and more resistant to damage than traditional barrel designs. This increased strength makes these barrels ideal for competition shooting, as well as roles such as self-defense where higher strength is important for stability and accuracy.NRA Guide To Ar15 Cartridges

Santa Barbara, California is a small city in the U.S. state of California. The population was seventeen thousand at the 2010 census, making it the third most populous city in Santa Barbara County. The city is located on an extreme southeast coast of Santa Barbara County and it straddles the Ventana range which separates Ventura County to its east and San Luis Obispo County to its west. The city is bordered by Morro Bay to the south and east, Carmel Valley to the north and west, Atascadero Creek to the northwest and south, and hills that rise abruptly from the Pacific Ocean viewport cover much of its interior landscape. The first Europeans who set foot in what is now Santa Barbara were Spanish missionaries who arrived in 1769 as part of General Antonio de Monterey's attempt to open up new territory for Spain along the Mexican border. Monterey's force consisted of about sixty men under Captain Francisco Narvaez y Arellano, while two hundred Native Americans assisted him including twenty-six Tahoe Indians led by Chief Kawaena (Caucasianized name: George Washington). A short time later Englishman John Copley arrived with his ship Discovery off shore searching for land route back home across Cape Horn so he could chart a course for India when he discovered this coastline during his own exploration in 1776 just northeast of where today's Santa Barbara sits.

The city of Santa Barbara was founded in 1598 by Spanish colonists as the Presidio of Santa Barbara. It became a U.S. territory on January 1, 1850, and was incorporated as a city on December 12, 1876. The population of Santa Barbara grew rapidly during the late 19th century and early 20th century due to its location on the Channel Islands and its access to good fishing grounds. The city experienced some explosive growth in the 1920s and 1930s due to World War II-era military construction and housing projects; however, it has since been declining in population.
