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The SL7 is no longer manufactured, having been replaced by the Heckler & Koch SLB 2000.
The HK 770, a hunting
rifle 7.62×51mm NATO/
.308 Winchester variant of the Heckler & Koch SL7, lacked the wooden handguard of the SL7 and was equipped with a longer
barrel with integral flash hider/compensator slots at the end of the barrel,
open rear leaf sights, and sporting-style
buttstock.

The HK 940, a hunting
rifle long action variant of the Heckler & Koch SL7, designed for using cartridges exceeding the 7.62×51mm NATO/.308 Winchester 2.8 in (71.12 mm) overall length like the
.30-06 Springfield or
7×64mm and lacked the wooden handguard of the SL7 and was equipped with a longer
barrel with integral flash hider/compensator slots at the end of the barrel,
open rear leaf sights, and sporting-style
buttstock.
