It is manufactured primarily  of aluminum alloys (Usually 7075) and synthetic materials (Your plastics). The AR-15 was first built by ArmaLite as an assault rifle for the United States armed forces.Due to financial problems, ArmaLite sold the AR-15 design to Colt. The select-fire version of the AR-15 entered the U.S. military system as the M16 rifle. Colt then started selling the semi-automatic version of the M16 rifle as the Colt AR-15 for civilian  sales in 1963. Although the name "AR-15" remains a Colt registered trademark,  there are variations of the firearm independently made, modified and  sold under different names and multiple manufacturers. Today there are  dozens of manufacturers creating entire rifles and/or specializing in specific  parts of the rifle.
