When first introduced in 1956, the AR-10 used an innovative combination of a straight-line barrel/stock design with phenolic composite, a new patent-filed gas-operated bolt and carrier system and forged alloy parts resulting in a small arm significantly easier to control in automatic fire and over 1 lb (0.45 kg) lighter than other infantry ...
The cartridge was more powerful than the 5.56mm NATO, exacerbating this problem. [ 7 ] [ 10 ] This made the M468 less reliable than the M4 carbine it was trying to replace. Barrett was still selling its limited stock of the M468 but only as an upper receiver kit and not as a complete rifle up until 2010.
The rifle has a radial block receiver similar to the Spencer, but the rounds were fed from an Archimedean-screw magazine which formed the spine of the rifle stock and could hold up to 28 rounds. The fluted cartridge carrier made a quarter turn each time the lever was operated, feeding a new cartridge into the breech.
The 6mm bullet is slightly wider, and the standard 6×35mm bullet slightly heavier, than the standard 5.56mm bullet (65 grains (4.2 g) versus 62 grains (4.0 g)). [ 1 ] Fired from a 10-inch (250 mm) barrel, KAC claims that the 6×35mm cartridge reaches a muzzle velocity of 2,450 ft/s (750 m/s), slightly faster than the muzzle velocity of a 5.56 ...
The rifle strips down into the following components for regular maintenance and cleaning: the receiver, stock, pistol grip and trigger group, handguard, bolt, bolt carrier and recoil mechanism. Handguards in the first several series were "square" in section (see LC picture), covering from magazine well to front sight.
In the meantime, the Army would continue testing the AR-15, finding that the intermediate cartridge .223 (5.56 mm) rifle is much easier to shoot than the standard 7.62×51mm NATO M14 rifle. [ 43 ] [ 44 ] In 1961 marksmanship testing, the U.S. Army found that 43% of AR-15 shooters achieved Expert, while only 22% of M14 rifle shooters did so.
