The Heckler & Koch SL6 is a roller-delayed blowback operated sporting carbine made by Heckler & Koch. It was chambered in 5.56×45mm NATO. The design was originally based on the Heckler & Koch 630 sporting rifle and is essentially a shorter-barreled version of that rifle. It was marketed throughout the world as a hunting/utility rifle.[1]

Design and operation

The roller-delayed blowback action is similar to that used in the Heckler & Koch G3 battle rifle and is the hallmark feature of Heckler and Koch's pre-Heckler & Koch G36 line of small arms. The four groove barrel features polygonal rifling with a right-hand twist of 270 mm or 1 in 10.6 inches. The chamber is fluted with 12 longitudinal flutes extending rearward from the baffle to the chamber face. These flutes permit propellant gases to flow around the case acting as a lubricant to ease extraction. The SL6 has a diopter sighting system and utilizes Heckler and Koch's proprietary HK 05 claw-type scope mount. Two rectangular recesses have been cut into the upper receiver to accept this mount.

Replacement

The Heckler & Koch SL6 is no longer manufactured, having been replaced by the Heckler & Koch SLB 2000.

Variants

The Heckler & Koch SL6A2 variant is essentially the same rifle; however, the SL6A2 includes a flash hider and offers a two-round burst selector.
The Heckler & Koch SL7 is a variant chambered in 7.62×51mm NATO.[2]
