A revolutionary rifle design-the HK SL8-NSR is constructed almost entirely of a reinforced carbon-fiber polymer. Based on the combat-proven G36 rifle used by the German Army, the SL8-NSR uses a proven short stroke, piston-actuated gas operating system, well known for simplicity and reliability. Designed and engineered to deliver exceptional shooting performance, the SL8 is a favorite among European target shooters, due in large part to its modular construction and free-floating bull barrel. A short Picatinny rail mount is standard and allows accessory optics to be easily added. Made using the famous HK cold-hammer forging process, the SL8-NSR barrel ensures accuracy and long life. The ergonomic and clean lines of the HK SL8-NSR are functional and modern, giving the SL8-NSR the look and feel of a 21st century firearm.
