Frequently Asked Questions

What is the MKb-42(W)?

The MKb-42(W) is the Walther-designed version of an early German Sturmgewehr (assault rifle) prototype developed during World War II. It was notable for its stamped sheet metal construction and gas-operated system.

How does the gas system of the MKb-42(W) work?

The MKb-42(W) employs a gas piston system. Gas from the barrel enters a chamber in the handguard, pushing a piston backward. This piston then strikes the operating rod, which cycles the bolt assembly to eject the spent casing and chamber a new round.

What were the key features of the MKb-42(W)'s construction?

A primary feature was its extensive use of stamped sheet metal, a manufacturing technique Walther was experienced with. This allowed for mass production. The handguard, for instance, was complex stamped metal riveted together.

What are the fire modes and safety features of the MKb-42(W)?

The MKb-42(W) has selective fire capabilities, with a separate selector switch for semi-automatic ('E' for Einzelfeuer) and full-automatic ('D' for Dauerfeuer) modes. It also features a distinct safety lever marked 'S' for safe and 'F' for fire.
