FN FNC

The FNC is an assault rifle chambered in 5.56mm NATO and manufactured by Belgian arms manufacturer Fabrique Nationale, or FN. Unlike the similar FN FAL, the FNC uses a long-stroke gas piston like the AK-47, while also inheriting features from the AR-15, making it a good, solid, all-around assault rifle. It's also the weapon that Al Pacino used in the bank heist scene in "Heat".

It's based on John Moses Browning designs, so it's guaranteed to be fucking awesome.
