The Model 1922 Bang rifle is a US semi-automatic rifle designed by the Danish arms designer Søren Hansen Bang. It was a modification of the earlier Models of 1909 and Model 1911 Bang rifles, both chambered in the .30-06 Springfield round.

Overview

[edit]

It was gas operated, using a sliding muzzle cup system which was blown forward by the combustion gases while the bullet emerged from the barrel. This ".256 Bang" rifle was a top candidate from 1925 to 1928 for US contracts ultimately won by the M1 Garand. Bang himself demonstrated his own models in US field trials in 1919 and 1927.[1] The Bang rifle was ultimately unsuccessful in US government testing because of its mechanical complexity and susceptibility to gas fouling of the sliding muzzle cup.

The Bang blow-forward gas system, originally developed in 1903, inspired several other weapon developments: it was used in the unsuccessful French Puteaux APX machine gun of 1904, in its direct successor the controversial St. Étienne Mle 1907 machine-gun, and in the Gewehr 41, where it suffered the same shortcomings.
