My first attempt at Pimp My Gun. More is to come.
This is a FN Herstal SCAR-H battle rifle, attached with a Mk.13 grenade launcher (specifically designed for the SCAR-H) and a Red Dot sight. It is chambered for the NATO standard 7.62mm x 51mm cartridge, and the Mk.13 takes 40mm grenades, in this case, a M651 chemical grenade. It is the standard issue rifle of the elite US SOCOM forces, and is the replacement for the M14 and Mk11 sniper rifles.
