The AR-5 was the basis of the MA-1 aircrew survival rifle adopted by the US Air Force in 1956 as a replacement for the M6 Aircrew Survival Weapon. The M6 is a superposed (over-under) combination weapon with a .22 Hornet rifle barrel over a .410 shotgun barrel. While there is an advantage to such a combination the AR-5 has the advantage of rapid fire using the same .22 Hornet cartridge as the M6’s rifle barrel.
