when was ar 15 made available to the public
Colt AR-15 Colt started selling the semi-automatic version of the M16 rifle as the Colt AR-15 in 1964.[1][2][3] The first mass production version was the Colt AR-15 Sporter, in .223 Remington, with a 20-inch barrel and issued with 5-round magazines.[2] Over the decades, Colt has made many different types of AR-15 rifle and carbine models, including the AR-15, AR-15A2, AR-15A3, AR-15A4, and many other models.
Comparison of the AK-47 and M16 The AK-47 was finalized, adopted and entered widespread service in the Soviet Army in the early 1950s.[27] Its firepower, ease of use, low production costs, and reliability were perfectly suited for the Soviet Army's new mobile warfare doctrines. More AK-type weapons have been produced than all other assault rifles combined.[28] In 1974, the Soviets began replacing their AK-47 and AKM rifles with a newer design, the AK-74, which uses 5.45×39mm ammunition.
