Ar15 upper receivers, or “ Upper” receivers are a type of firearm that utilize an armament grade barrel and magazine. The first Ar-15 rifles were manufactured in the early 1970s utilizing a shortened and lightweight barrel which greatly reduced the weight and complexity of the rifle. As time passed, barrel rifling became more advanced and multiple choke tubes were added to increase muzzle velocity for greater accuracy. Today, Upper receivers are made from all sorts of materials including aluminum, steel, brass, titanium, molybdenum, carbon fiber and composites. Each material has its own unique properties that contribute to its function as an upper receiver on a firearms system. The origins of the Ar-15 rifle can be traced back to 1969 when Ordnance Department specifications called for a lightweight but effective rifle with high firepower potential for use in close quarters combat situations. In response to these specifications, Colt began manufacturing the AR-1 Rifle which utilized a shortened 60in(18cm) barrel with 1:8 twist rate. This weapon was designed as an experimental platform for further development of new technology within Colt Firearms Corporation. It wasn’t until 1976 that production commenced on the original AR-15 design which would later become known as the M16A2 Rifle. During World War II both American forces and their Axis counterparts used older bolt action rifles chambered in 7x57mmR (303mm) caliber named after European rifles such as Nazi Germany’s Sturmgewehr 44 (assault rifle), Italian Beretta 75 ( sniper rifle), British Browning Hi-Power MkIII ( submachine gun), German Gewehr 40/7 (.30cal) assault rifle etc…. Many old rifles continued in service into the postwar period such as Japan’s Type 99 “Grendel” sniper rifle whichfired 7x55mmR ammunition; it could fire at over 645miles per hour with good accuracy! By 1948 Brazilian arms company is producing Rifles chambered in 7x57mmR cartridge name followed by United States Arms Corp., Winchester Repeating Arms Co., SIG Sauer & Co., Savage Arms Incorporated…..By 1970 Armees had started using Soviet AK series assault rifles chambered in 7x54mmR cartridge similar to 8x56SR rounds being produced by NATO countries like France etc..... All these various models entered Service during Vietnam War era………………..In 1972 US military decides there will not be any more large scale wars fought against other major powers so they develop smaller calibers like 5.56 NATO instead…………….. overall Armees produces about 50 million Unifled Arms weapons……………………………………… eventually these weapons fall into disrepair or are discontinued……………….. until now

The AR15 upper receiver is a firearms system that uses a stock rifle and barrel to fire a projectile. The upper receiver stores the gun's operating components, including the trigger, sights, magazine well, and other parts necessary for firing shots. The upper receiver also includes an accessory rail on which various accessories can be attached. The weapon systems designed by Colt have been popular with shooters for many years and are still in use today. This popularity comes from their design of an easy-to-use firearm that is reliable and easy to maintain. Additionally, these firearms systems offer features that make them ideal for hunting or target shooting.

Richmond, California is a city located in the Central Valley of California, on the east side of San Joaquin River. As of 2014, it had a population of over 234,000 people. It is the second-largest city in Northern California after San Francisco and is one of the most populous cities in Southern California. The area now known as Richmond was part of Alta California before it was acquired by Mexico in 1848. The first European to visit what is now Richmond was Juan Rodríguez Cabrillo on October 2, 1542. He named the area Los Angeles Bay after his hometown Spain. The City of Richmond was incorporated on November 14, 1847. On December 6, 1850, it became part of newly formed Contra Costa County when all but two of its members were included in that county's creation. In 1853–1854 an act was passed which designated Richmond as the site for a new county courthouse to be built by Samuel Dorman and Alfred Bancroft because they felt that San Francisco would not meet their needs for an official county seat until another site could be found nearby. After more than 40 years as county seat, Berkeley took over from Richmond as the new County Seat on January 3, 1856. In 1865 Mayor John Hay decided to move from Berkeley to take up residence at former military barracks called Fort Point onkielbeth Cove which he purchased from Commodore Matthew Perry during his visit to America during July 1865 (the Battle Of Imperial Beach). At that time there were no paved streets and only unpaved trails led to points near Navy Yard where goods could be unloaded onto ships coming into port or delivered inland; this system later became known as "Hay Street". When Hay died in 1870 his son George Cushing took over mayoral duties and continued expanding Fort Point until 1888 when Commodore John Wainwright replaced him at sea and consolidated American naval forces at Yokosuka Naval Base with Japanese military forces under Emperor Meiji's orders which resulted in Japan's withdrawal from World War I much earlier than planned due to United States declarations of war against Germany – henceforth called World War I – then began preparations for World War II based upon Japanese assurances that prior thereto no aggressive action would take place within American territory . As seen above: throughout these times there have been various landmarks located within today's boundaries of Downtown Richmond including: First Baptist Church (now Cathedral Basilica), Nelson & Dunlop stores across Main Street between Cary Avenue and Cesar Chavez Avenue/National Blvd., old Russian Orthodox Cathedral Square at Seventh Street & Hwy 1 North - home today also to St Mary’s Catholic Secondary School (formerly St Ignatius High School), numerous bars/restaurants along Broadwalk avenue west between Fifth street entranceway off Interstate 5 northbound lane & Interstate 580 southbound lanes - many still open since prohibition ended nearly 80 years ago!

Richmond was founded in 1747 by Captain James Robertson as a trading post on the American River. The city grew rapidly and by 1871, it had outgrown its original boundaries. In 1853, Richmond became an incorporated city under the leadership of Mayor George Neilson. During the late 19th century, Richmond underwent a significant transformation with the arrival of large numbers of immigrants from Southern China and other parts of Asia. This change led to new neighborhoods being developed around Chinatown and Japanese Harlem. In 1916, Richmond became one of the first cities in California to allow women to vote.
