https://stream.echo6.co/videos/watch/1ad51850-974f-4ed6-aa55-7dd2624280dd The very first AR15 rifles submitted to US government trials were extremely light weight, with an assortment of interesting features that did not last long. They had top-mounted charging handles, one-piece hand guards, very thin barrels with plain muzzles, and a different safety selector configuration than became normal later one. Updates and modifications were made to virtually all of the original rifles, but today we have a chance to look at serial number 6 in the Springfield Armory collection - which is still in completely original configuration. Thanks to the Springfield Armory National Historic Site for giving me access to this truly unique specimen from their reference collection to film for you!
