Rossignol ENT


The Rossignol ENT was an experimental automatic rifle of French origin from the first years of the 20th century. It was the first rifle which used the direct impingement operating system, which found later use in the Swedish Ag m/42 and the French 1940 MAS rifles, and was later used in the American M16 rifle.
Rossignol developed the new impingement system, and modified the Friberg-Kjellman system of opposing, retractable bolt lugs for this experimental rifle. The rifle was produced under the École Normale de Tir, thus the ENT designation, and was produced in at least four variants, "ENT No. 1 or B1, B2, B4, B5".
