The **Rossignol ENT** was an experimental [automatic rifle](/source/Automatic_rifle) of French origin from around the first years of the 20th century. It was the first rifle which used the [direct impingement](/source/Direct_impingement) operating system,[2] which found later use in the Swedish [Ag m/42](/source/Ag_m%2F42), the French [1940 MAS](/source/MAS-49_rifle) and, most notably, the [AR-10](/source/AR-10) and [AR-15](/source/AR-15) series of rifles.

Rossignol developed the new impingement system, and modified the Friberg-Kjellman system of opposing, retractable bolt lugs for this experimental rifle.[3] The rifle was produced under the [École Normale de Tir](https://en.wikipedia.org/w/index.php?title=%C3%89cole_Normale_de_Tir&action=edit&redlink=1), thus the ENT designation, and was produced in at least four variants, "ENT No. 1 or B1, B2, B4, B5".[4]
