At the time of selection, there had been criticism that the recoil power of the 7.62×51mm NATO, when fired from a handheld lightweight modern service rifle in full automatic mode, did not allow for sufficient control, so the automatic follow-on shots would not hit the intended target but scatter around it.

The British had extensive evidence from their own experimentation with intermediate cartridges since 1945, and were on the point of adopting the .280 (7 mm × 43mm) cartridge when the selection of 7.62×51mm (.308) as the NATO standard was made.

The United States overruled concerns about the recoil and overall effectiveness of 7.62 mm, and the other NATO nations accepted that standardization was more important than the selection of a cartridge that was otherwise ideal.

The development of the cartridge that eventually became the .223 Remington (from which 5.56mm NATO would eventually be developed) would be intrinsically linked to the development of a new lightweight combat rifle. The cartridge and rifle were developed as a single unit by Fairchild Industries, Remington Arms, and several engineers working toward a goal set by the U.S. Continental Army Command (CONARC).

Early development work began in 1957. A project to create a small-calibre, high-velocity (SCHV) firearm was created. Eugene Stoner of Armalite was invited to scale down the AR-10 (7.62mm) design. Winchester was also invited to participate. 5.56×45 Ammo For Sale now in stock
