The HK93 is the semi-automatic civilian version of the HK33 assault rifle, scaled down from the G3/HK91 platform to fire 5.56x45mm. The same roller-delayed blowback mechanism of the G3 is retained, giving the HK93 a distinctly different manual of arms and recoil impulse compared to gas-operated AR-15s. Imported until 1989. A collector staple for fans of the HK roller-locked family. Type: Rifle Action: Semi-Automatic Caliber: 5.56x45mm Capacity: 30 Year introduced: 1974, Germany Weight: 186 oz Overall length: 37" Status: Discontinued Intended use: collector, sporting, historical
