| − | The '''''Krummlauf''''' (English: Curved barrel) is a bent [[barrel]] attachment for the [[StG 44|Sturmgewehr 44]] [[assault rifle]] developed by Germany in [[World War II]]. The curved barrel included a periscope sighting device for shooting around corners from a safe position.

| − | ==Description==
| + | |
| − | It was produced in several variants: a "I" version for infantry use, a "P" version for use in tanks (to cover the dead areas in the close range around the tank, to defend against assaulting infantry), versions with 30°, 45°, 60° and 90° bends, a version for the StG 44 and one for the MG 42. Only the 30° "I" version for the StG 44 was produced in any numbers.

| − | The bent barrel attachments had very short lifespans – approx. 300 rounds for the 30° version, and 160 rounds for the 45° variant–as the barrel and bullets fired were put under great stress.

| − | Another problem besides the short life-span was that the bending caused the bullets to shatter and exit the barrel in multiple fragments, producing an unintended shotgun effect. As a result, weapons designers experimented with small vent holes drilled into the Krummlauf's barrel in order to reduce pressure and recoil, allowing the discharged bullets' built-up gases to be released to slow the bullet's velocity as it turned to exit the barrel. Nevertheless, the Krummlauf's lifespan remained the same. The 30° model was able to achieve a 35x35 cm grouping at 100m. One of the biggest drawbacks of the small number (91 conversions) of [[wikipedia:Elefant|''Panzerjäger Tiger (P)'']] casemate-type tank destroyers was that in spite of having a 88mm anti tank gun, the initial ''Ferdinand'' version of the ''Elefant'' did not have a forward-facing hull mount machine gun to handle enemy infantry. Hence, the Krummlauf was fitted with the Stg44 Gun and used by the tank crew as a machine gun.
