The .30 Remington AR / 7x39mm Remington AR is an intermediate cartridge created in 2008 by Remington Arms to fill a perceived gap in performance on large game between the .223 Remington and larger cartridges such as the .308 Winchester.[1] The design of the cartridge is considered a joint effort between companies under the "Freedom Group" name through a private equity firm[1] and included such companies as Bushmaster, DPMS and Remington itself. It is a rebated rim cartridge designed to fit Remington's R-15 semiautomatic hunting rifle. It was made to fit the dimensional constraints of the AR-15 magazine and is based on a modification of the .450 Bushmaster, which in turn is based on the .284 Winchester.[2]
Remington was the only company that manufactured this ammunition and its components.[3] The cartridge was a commercial failure and has been discontinued by Remington.
