Authentic down to the last detail
Classic design & modern airsoft-technology. Based on the proven G3, the HK33 has been scaled down and was switched from .308 to .223 – mirroring the U.S. Armed Forces’ transition to its new standard caliber at the time.

With its fixed stock, the etablished G3 design and that reliable roller-delayed blowback system, the HK33 quickly made its mark in the market.

The 6 mm GBB airsoft variant from UMAREX stands out with its incredibly realistic design. A stamped steel receiver combined with fiber-reinforced polymer parts ensures an authentic feel, further enhanced by the steel charging handle. Powerful blowback, an adjustable Shoot-Up, and the NPAS (blowback regulator) round out this high-end technical package.
A total highlight for players and collectors alike who value an original HK look and feel, premium craftmanship, and modern tech.
