The table below gives a list of firearms that can fire the 5.56×45mm NATO cartridge, first developed and used in the late 1970s for the M16 rifle, which to date, is the most widely produced weapon in this caliber. [1]
The ammunition specific lever-delayed blowback mechanism of the FAMAS F1 designed around French 55 gr (3.6 g) steel cased ammunition was slightly revised for reliably using 5.56×45mm NATO ammunition.

The lever essentially ratchets into place with friction, providing enough resistance to being re-opened that the bolt carrier does not rebound. Due to the relative low bolt thrust exhibited by pistol cartridges the anti-bounce mechanism is omitted by Heckler & Koch on their roller-delayed blowback firearms chambered for pistols cartridges.
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.
While the Olin WC 846 powder achieved the desired 3,300 ft (1,000 m) per second muzzle velocity, it produced much more fouling, which quickly jammed the M16's action (unless the rifle was cleaned well and often). [27] In March 1965, the Army began to issue the XM16E1 to infantry units.
