For example, a rifle capable of firing a ½ or 0.5 MOA (approximately 0.5 inch center to center of the two holes furthest apart) 5-round group (often referred to as "grouping") at 100 yards will theoretically fire a 12.5 inch group at 2,500 yards (0.5 × 2,500/100 = 12.5). Unless the group is centered perfectly on the target at 100 yards, the ...
It appears that this round can drastically improve the performance of any AR-15 weapon chambered to .223/5.56 mm. Superior accuracy, wounding capacity, stopping power and range have made this the preferred round of many special forces operators, and highly desirable as a replacement for the older, Belgian-designed 5.56×45mm SS109/M855 NATO round.
The ArmaLite AR-15 [note 3] is a gas-operated assault rifle manufactured in the United States between 1959 and 1964. [10] Designed by American gun manufacturer ArmaLite in 1956, it was based on its AR-10 rifle. The ArmaLite AR-15 was designed to be a lightweight rifle and to fire a new high-velocity, lightweight, small-caliber cartridge to ...
The 5.56 mm round had to penetrate a standard U.S. helmet at 500 yards (460 meters) and retain a velocity over the speed of sound while matching or exceeding the wounding ability of the .30 carbine cartridge. [50] This request ultimately resulted in the development of a scaled-down version of the Armalite AR-10, named the ArmaLite AR-15. [51]

The result was a weapon with somewhat less accuracy than the .308Win (7.62×51mm NATO) rounds, but with equal penetration and a trajectory so flat it could be fired with no sight adjustment out to 400 yards (370 m). Better yet the rounds were very light, and had almost no recoil in comparison to even the .22-caliber weapons under development.
Prior to the development of the CAL, FN had already constructed a scaled-down FAL prototype before shelving the idea as unmarketable. Noting the growing sales success of the cheaper and simpler HK G3 rifle, FN decided that for any future rifle to be competitive in the marketplace, it would need to use fewer expensive precision-machined parts.
