This short video was sent to us by Alex, who is a friend to the website. Alex owns one of the rare Colt IAR uppers and fired it on full auto. The Colt IAR was colt’s submission for possible adoption for the USMCs new automatic rifle. Of course the HK won. Not because it was better, released documents showed the colt submission performed better, but because HK has the ability to influence things beyond the actually quality of their firearms.. ahem.
Alex fired the gun on full auto with a magazine about half and half of Federal Fusion and M855. You can tell the difference in the cyclic rate while he is shooting,
