i myself an an fn-fal owner, i absolutely love the weapon, but agree with those that say it all comes down to shooter preference. My younger brother has a setme .308, and he feels the same way about his weapon. anywho, the following info came from Wikipedia, enjoy!
In 1947, the first FN FAL prototype was completed. It was designed to fire the 7.92 mm Kurz patrone (short cartridge) developed and used by the forces of Nazi Germany during World War II (see StG44 assault rifle). After testing this prototype in 1948, the British Army urged FN to build additional prototypes, including one in bullpup configuration, chambered for their new .280 British calibre intermediate cartridge. After evaluating the single bullpup prototype, FN decided to return instead to their original, conventional design for future production.
In 1950, the United Kingdom presented the redesigned FN rifle and the British EM-2, both in .280 British calibre, to the United States for comparison testing against the favored United States Army design of the time - Earle Harvey's T25. It was hoped that a common cartridge and rifle could be standardized for issue to the armies of all NATO member countries. After this testing was completed, U.S. Army officials suggested that FN should redesign their rifle to fire the U.S. prototype '.30 Light Rifle' cartridge. FN decided to hedge their bets and cast their lot with the U.S., given that the UK appeared to be favoring their own EM-2.
In 1951, FN even made a deal with the U.S. that they could produce the FAL royalty-free in the U.S. This decision appeared to be correct when the British unilaterally decided to adopt the EM-2 and .280 British cartridge in the very same month. This decision was later rescinded after the Labour Party was ousted from control of Parliament and Winston Churchill returned as Prime Minister. It is believed that there was a quid-pro-quo agreement between Churchill and U.S. President Harry Truman in 1952 that the British accept the .30 Light Rifle cartridge as NATO standard in return for U.S. acceptance of the FN FAL as NATO standard. The .30 Light Rifle cartridge was in fact later standardized as the 7.62 mm NATO; however, the U.S. insisted on continued rifle tests. The FAL chambered for the .30 Light Rifle went up against the redesigned T25 (now redesignated as the T47), and an M1 Garand variant, the T44. Eventually, the T44 won out, becoming the M14. However, in the mean time, most other NATO countries were evaluating and selecting the FAL.
FN created what is possibly the classic post-war battle rifle. Formally introduced by its designers Dieudonne Saive and Ernest Vervier in 1951, and produced two years later, it has been described as the "right arm of the free world." The FAL battle rifle has its Warsaw Pact counterpart in the AK-47, each being fielded by dozens of countries and produced in many of them. A few, such as Israel and South Africa, manufactured and issued both designs at various times. Unlike the Russian AK-47 assault rifle, the FAL utilized a heavier full-power rifle cartridge. In the West, FAL's primary competitor was the German Heckler & Koch G3.
The FAL operates by means of a gas-operated action very similar to that of the Russian SVT-40. The gas system is driven by a short-stroke, spring-loaded piston housed above the barrel, and the locking mechanism is what is known as a tilting breechblock. To lock, it drops down into a solid shoulder of metal in the heavy receiver like the bolts of the Russian SKS carbine and French MAS-49 series of semi-automatic rifles. The FAL's magazine capacity ranges from 5 to 30 rounds, with most magazines holding 20 rounds.
Despite using a full-power .30 cartridge, the FAL's recoil is relatively light. This is due mainly to the rifle's weight, but also to its gas-operated design. In fully-automatic mode, however, the shooter receives considerable abuse from recoil, and the weapon climbs off- target quickly. Most military forces adopting the FAL eventually eliminated full-automatic firearms training in the light-barrel FAL.
