In the early 1960s the famous small arms designer Eugene Stoner (Eugene Stoner), after leaving the company Armalite, began work on developing a new system of small arms.
In 1962 Yu Stoner has developed a prototype of a new weapon caliber 7.62x51 mm, designated Stoner 62.
In 1963 Stoner introduced the system of small arms Stoner 63, but chambered 5.56h45 mm, which was built based on an earlier system of Stoner 62.
basic concept Stoner 63 system was full modularity for quick reconfiguration of weapons to resolve various tactical missions - assault rifle, a shortened rifle, machine gun, a single gun.

system of small arms Stoner 63 comprised just under 20 major components that allow on the basis of a single central receiver module in the field to collect the most different types of weapons. In this complex consisted of a quick change barrel, detachable modules of the trigger assembly with a pistol grip, detachable power supply modules cartridges (supplies of ammunition box magazine or cartridge tapes), modules of different types of scopes.
This flexibility allows for equipping infantry weapons actually a single sample with interchangeable parts, a unified scheme of service. This approach considerably simplifies the logistics service infantry units, but the price for this is somewhat grown mass of weapons compared to highly specialized samples, as well as potentially a somewhat lower reliability (by increasing the number of components and detachable components in each sample was compared with the specialized models of weapons).
proposed system consisted of the following options weapons:
- Stoner 63 / 63A AR (Automatic Rifle) - automatic rifle.
- Stoner 63 / 63A Carbine - carbine version Stoner 63/63A AR with a short barrel and folding butt.
- Stoner 63 Survival Rifle - a compact machine designed for pilots and aircraft as weapons of survival in hostile territory.
- Stoner 63 / 63A LMG (Light Machine Gun) - a light machine gun.
- Stoner 63 / 63A MMG (Medium Machine Gun) - medium machine gun, for use on tripods and machines.
- Stoner 63 / 63A FMG (Fixed Machine Gun) - machine gun fixed mount for use on military vehicles.
- Stoner 63 / 63A Commando - a shortened version of Stoner 63 / 63A LMG.
The basis of all the options

Automatic (assault rifle)
arms Stoner 63 system was a single receiver with visiting her node locking and venting mechanism. Locking performed for breech, rotating bolt, 7 lugs. Vapor mechanism had long stroke gas piston. In an assault rifle and carbine receiver positioned so that the gas discharge unit located above the barrel, in all variants guns receiver flips "upside down" and vent assembly is under the barrel.
View of the receiver box
Receiver was made by stamping sheet steel fasteners and had room for all the other elements in the form of weapons lugs into which the transverse connecting pins.
charging handle on the gun series Stoner 63 was attached to the bolt carrier on the right and on the modified Stoner 63A weapon series - on the gas piston rod and the piston protrudes from the housing up or down (on the rifle or carbine and machine guns, respectively).
Recoil in all variants located in the receiver behind the gas piston rod.
ammunition supply unit was attached to the "bottom" of the receiver, that is always relative to the trunk was on the same side as the gas discharge unit. Node power could be either in the form of box-lane receiver 30 stores capacity cartridges or in the form of loose lentopriemnika tape cartridge. Supply node attached to the receiver for the front pair of lugs.

the rear of the receiver symmetrically with respect to the horizontal plane of weapons housed two identical sets of eyelets, which is attached module trigger mechanism (USM) with a pistol grip and a module scope. In embodiments of rifles and machine USM module fastened "from below", ie with the same side of the receiver, and that receiver stores. In this module USM included trigger trigger mechanism, and can fire only with a closed gate. "Rifle" USM provides 2 modes of fire - single shots and automatic.
Stoner 63 weapons fire also served as a translator and the role and the fuse located on the left of the trigger housing. On an improved system Stoner 63A fuse was made a separate piece, located in front of the trigger guard, front of the trigger.
sighting assembly includes a front sight mounted on the barrel in accordance with the purpose of the trunk. Rear sighting unit was installed in the rear of the receiver and included diopter rear sight adjustable for elevation and distance, or open a machine gun sight.
Weapon System Stoner had 63 plastic pistol grips and butts of various designs - fixed or folding sideways.
In the embodiment
"rifle" Stoner 63 weapon could be completed bayonet and easy detachable folding bipod, standard for "machine gun" configuration.

Automatic (assault rifle)
In the mid-1960s models of weapons systems Stoner 63 were tested in the U.S. armed forces under the designation HM22 (assault rifle), HM23 (automatic rifle), HM207 (light machine gun with belt feed).
army test results, and especially operating systems Stoner 63A Vietnam showed high standards of these weapons to the quality of care and service, in combination with other features, and determined the commercial failure of this project.
None of the samples of small arms Stoner 63 / 63A adopted the U.S. has not been accepted. Only the U.S. Navy in the late 1960s, they have bought for their special forces (US Navy SEAL) a small amount of light machine guns Stoner 63A with belt-fed and used them during the Vietnam War under the designation Mk.23 mod.0.
In 1971, production of small arms Stoner 63 and 63A was discontinued. Total number of weapons produced between 1963 and 1971, amounted to about 3,500 - 4,000 units.
In all of this, the idea of the famous designer in the form of small arms Stoner 63 / 63A ahead of its time for 15 years, since in 1977 the first mass modular system of small arms - Steyr AUG was put into service in Austria.
In 1999, after the death of Eugene Stoner (1997), the concept and the overall design of its systems Stoner 63 were again in demand. Thus, a small American company Robinson Armament Co, based on design Stoner 63 system was established firearms Robarm M96.
