is still in active service in many nations (none of which are in NATO), most notably Brazil. In total, the FAL has been used by over 90 countries, and over 7,000,000 have been produced, leading to the rifle's other, unofficial name: "The Right Arm of the Free World." Heckler & Koch G3 The 'Heckler & Koch G3 (Gewehr 3) is a roller-delayed blowback operating system rifle developed in the 1950s by the German armament manufacturer Heckler & Koch (H&K) in collaboration with the Spanish state-owned design and development agency CETME (Centro de Estudios Técnicos de Materiales Especiales), firing 7.62×51mm NATO from 5-, 10-, 20-, 30-, or 40-round detachable box, and 50-round and 100-round drum magazines. It was first produced in 1959. The modular designed G3 has over the years been exported to over 70 countries and manufactured under licence in at least 15 countries, bringing the total number built to around 7,800,000. M14 The M14 rifle is an American design, made to replace the M1 Garand, which was used as the basis for the M14. It is a fully automatic weapon, firing 7.62×51mm NATO from 20 round box magazines, and was primarily used during the Vietnam War, but once deployed into combat, there were complaints about the weapon's performance, predominantly that it was too difficult to control in full auto, its profile was too long, and the weapon was generally unreliable – a 1962 Department of Defense report described it as "completely inferior" to the M1 Garand. It went into production in 1959 and about 1,300,000 M14 rifles have been produced. The M14 was eventually replaced by the M16 assault rifle which was a controversial decision – the M16's weaker round, combined with the fact it was much smaller and lighter, and had plastic furniture instead of wood, led some soldiers to sardonically call the rifle the 'Mattel 16'. Despite initial shortcomings, however, the M16 remains in American military service to this day, and it is the most produced rifle in its caliber. Contemporary usage After the United States formally adopted the M16 rifle, the precedent was set. Because they were more controllable, much lighter, and still offered acceptable levels of penetration, intermediate cartridges were considered a better choice, and gradually battle rifles began to be replaced with weapons such as the Steyr AUG, Heckler & Koch G36, FAMAS, and SA80. However, battle rifles do continue to be used in
