The HK33 was the reaction of Heckler & Koch to the introduction of the caliber .223 in the US Army as the new standard.
The lower recoil and the quantity of rounds a soldier could carry with the same weight were the main reasons for the change.
The HK33 is based on the G3, but is slightly smaller and was introduced in cal. .223.
With the fix stock and the G3 design, it quickly gained popularity on the market. The roller-delayed blowback system was kept from the G3.
Out in the field, the gas-operated Airsoft version is a great choice for challenging matches. The robust steel stamping body and glass-fiber-reinforced polymer closely emulate the original and give the HK33 an authentic feeling. A steel cocking lever matching that of the original, the typical drum sight and a ergonomic stock perfect the rifle´s convincing looks.
And the HK33’s performance too matches its excellent appearance: a factory-fitted NPAS is available, the hop-up is adjustable, and a strong blowback produces a noticeable recoil with every shot. The threaded barrel (M14x1, CCW) permits fitting of standard tracer units, silencers and other accessories.
