Firearms expert Jonathan Ferguson of the Royal Armouries details the Krummlauf, an experimental curved barrel attachment for the StG44. Developed by Rheinmetall-Borsig, it aimed to enable shooting around obstacles or from vehicles via periscope. Despite technical challenges like limited barrel life and sighting system durability, it represented a unique German wartime innovation.
This video features firearms expert Jonathan Ferguson exploring a unique American prototype firearm based on the M3 Grease Gun, designed to shoot around corners. It's compared to the German Krummlauf and is referred to as the M3 'Deflector'. The video delves into its 90-degree firing capability, potential use in tanks or armored vehicles, its "Infinity Sight," and its unusual yellow coloring. Ferguson also discusses the removal of the curved unit, reports on its accuracy and lethality, and touches upon the legacy of curved barrels, drawing a parallel to the modern CornerShot system. The content is presented by the Royal Armouries.
The Krummlauf was a late-WWII German attempt to solve tank 'dead zones' with a curved barrel, but Hitler's infantry order led to rushed, flawed development. Early tests with the K98k failed, shifting focus to the StG-44. Despite versions for tanks and infantry, severe technical issues like short barrel life (60-160 rounds) and abysmal accuracy plagued the program, rendering it a historical failure.
This review details the Krummlauf, a rare curved barrel attachment for the StG-44 designed for specific combat scenarios. It explores its development, including 30-degree and 90-degree variants for urban combat and armored vehicle use, respectively. The review highlights its mechanical attachment, gas relief features, and optical sighting system, while also noting significant limitations like bullet fragmentation and a short barrel life.
