We created the HK433 with a clear objective: The merging of two HK assault rifle worlds into one unique, scalable and highly efficient weapon platform for military and police users. The HK433 is the foundation of a modular assault rifle system with the NATO standard calibre 5.56 mm x 45 and it makes a clear statement: It combines the best of the G36 and the HK416 in a peerless, state-of-the-art assault rifle architecture.
