The Armalite AR-5 is a lightweight bolt-action rifle, chambered for the .22 Hornet cartridge, and adopted as the MA-1 aircrew survival rifle by the United States Air Force. It was developed by ArmaLite, a division of Fairchild Engine and Airplane Corporation in 1954.

History

The Air Force needed a compact, lightweight, accurate rifle for North American XB-70 Valkyrie manned bomber aircrew's survival kits.[2] The AR-5 was submitted in response to a US Air Force request shortly after ArmaLite was established on October 1, 1954, and was officially adopted as the MA-1 in 1956.[3][4] However, the Air Force never received funding to buy more than the original 12 test models due to the cancellation of the XB-70 and due in part to the number of M4 and M6 survival weapons already in the inventory.[5][6][7] The MA-1 established ArmaLite as a recognized firearms company, leading to several other rifle designs of varying success (e.g., the AR-7, AR-10 and AR-15).

Design

22 Hornet

The earlier M6 Aircrew Survival Weapon is a superposed ("over-under") combination weapon with a .22 Hornet single-shot rifle barrel over a .410 shotgun barrel. While there is versatility to such a combination, the AR-5's detachable box magazine fed bolt action has the advantage of rapid fire capability. The AR-5, like the M4 Survival Rifle and M6 US Air Force survival rifles, used the .22 Hornet cartridge which has 2.3 times the muzzle velocity and 7 times the energy of the common .22 Long Rifle (when comparing 40 gr bullets), and yet still has a light recoil.

Designed to be stowed in cramped aircraft cockpits, the rifle was made from lightweight plastics and aluminum alloys. The AR-5 was unique for being able to be disassembled with all working parts stored within the stock. When stowed in this manner, the rifle was able to float.[8]

Armalite used the research and tooling for the AR-5/MA-1 to develop the AR-7, an eight-shot semi-automatic rifle chambered for the .22 Long Rifle cartridge. Released in 1959 as a civilian survival weapon and in continuous production since then, the AR-7 is related to the AR-5 in terms of its overall layout, and retains the same modular takedown, storage in stock, and the ability to float.[3]
