The Heckler & Koch SL7 is a roller-delayed blowback operated sporting carbine made by Heckler & Koch. It was chambered in 7.62×51mm NATO caliber and designed and marketed throughout the world as a hunting/utility rifle.[1]
Unlike the roller-delayed blowback military Heckler & Koch rifles the cocking handle is situated far more rearward and on the right side and features a camming system to help overcome the initial friction exerted by the "bolt head locking lever" anti-bounce mechanism that prevents the bolt from bouncing off the barrel's breech surface.
The SL7 is no longer manufactured, having been replaced by the Heckler & Koch SLB 2000.
