Frequently Asked Questions

What defines an assault rifle according to Ian McCollum?

An assault rifle is defined as a selective-fire weapon capable of both semi-automatic and full-automatic fire, chambered for an intermediate caliber cartridge. This means it's more powerful than a pistol round but less powerful than a full-size rifle round.

What caliber is the MP-44 Sturmgewehr chambered in?

The MP-44 Sturmgewehr is chambered in the 8x33mm Kurz cartridge. This round features a 125-grain projectile fired at approximately 2,200-2,300 feet per second.

How is the MP-44 constructed, and why?

The MP-44 is primarily constructed from stamped sheet metal due to wartime shortages of high-strength steel. A milled trunnion is used for pressure containment, while stamped parts form the main body for efficiency and cost-effectiveness.

What are the key external controls on the MP-44?

The MP-44 features an ergonomic magazine release, a safety lever marked 'S' (Safe) and 'F' (Fire), and a cross-bolt fire mode selector marked 'E' for single fire (Einzel) and 'D' for continuous fire (Dauerfeuer).
