The SL8-6 configuration pairs HK's short-stroke gas piston system with a 20.8 in heavy-profile, steel barrel that is cold hammer forged and chrome lined, capped with a target crown. The 1:7 in, 6-groove right-hand twist supports a broad range of .223 Rem projectiles while maintaining precise rifling detail.
The chassis, receiver, stock, and handguard are built from fiber-reinforced polymer in black, delivering rigidity with reduced weight. The thumbhole stock features an integral cheekpiece and the HK red logo, and the ventilated polymer handguard aids heat management. Front and rear sling attachment points are factory provisioned.
Controls include a manual safety and HK's ambidextrous, folding top charging handle. The rifle is set up with right-side ejection and a long MIL-STD-1913 Picatinny top rail. Iron sights are not installed on this model.
