Fabrique Nationale.

The developer of premier, hi-tech personnel firearms. FN has been popularly known to be the developer of the HP handgun (in association with Browning). But now FN will be well-known for being the developer of two revolutionary new weapons : the Five-seveN handgun and P90 submachine-gun. Both of these are chambered in the FN-made catridge of 5.7x28mm. This caliber is designed to be convenient like a handgun, but devestating like an assault rifle (these bullets have armor-piercing capabilities).
FN has also made the premier M249, which is a 200-round, 5.56x45mm NATO machine-gun. FN has also made the FNC ("Free Nation's Rifle"; it somewhat resembles the Israeli Galil, in fact borrows traits from it, among others) and FAL (the FAL almost resembles an H&K G3A3), both of which are little-known, kind of.

But my most favorite guns from FN are the Five-seveN and P90. ^_^
