Heckler & Koch HK433

History of the Heckler & Koch HK433

In 2017, the long-established German arms manufacturer unveiled its latest vision - a fully modular, compact and lightweight Assault carbine. The product relies on the proven 5.56 x 45mm NATO Medium Rifle cartridge, fired from a 30-round arc magazine.

The rifle/carbine was launched during EnforceTac 2017 and maintains a positive marketing presence in Heckler & Koch's range of firearms.

The basic design of the weapon is traditional by modern standards and incorporates many of the features proven in previous designs. There is full ambidextrous support, inherent "quick swap" barrel capability, and tool-less left/right charging grip design. The weapon can be cocked in all safe positions and has a circular counter built into the casing.

The stock is foldable and retractable and features an adjustable inspection tab for precision shooting at long distances. The weapon can be fired with the stock folded/folded.
