FN Herstal showcases its MAG and SCAR rifles at DSEI 2013.

The FN MAG (Mitrailleuse d'Appui Général) is 7.62 mm general-purpose machine gun is displayed here at DSEI 2013. The latest big order for this machine gun was from the French Army a couple of years ago. They ordered 10,000 pieces to replace their older AA-52 and AA-NF1.

The Special Operations Forces Combat Assault Rifle (SCAR) is a modular rifle available in two versions:
The SCAR-L, for "light", is chambered in the 5.56×45mm NATO cartridge.
The SCAR-H, for "heavy", fires 7.62×51mm NATO.

Both are available in Long Barrel and Close Quarters Combat variants and can be fitted with a FN40GL (40mm grenade launcher). FN40GL system features a double action trigger and a swing out chamber; meaning the launcher does not need to be re-cocked if the grenade does not fire, and that longer grenades can be used.
A sniper variant, Sniper Support Rifle (SSR) called SCAR-H PR, is also showcased here at DSEI 2013.
