The Heckler und Koch SL8 is a sporting rifle manufactured by Heckler und Koch. It is the civilian version of the Heckler und Koch G36.
The rifle fires the .223 Remington or 5.56x45mm NATO cartridge and feeds from a 10, 20 or 30 round detachable magazine (depending on the variant of the rifle). Unlike earlier types of HK rifles, it is not a roller lock bolt but rather a lug type rotating bolt system as seen on the AR-18. The SL8 was originally developed for the German Bundeswehr, to provide a weapon for training reservists similar to the G36 and able to be provided to reserve organizations not able to provide military grade armaments.
