Description


Introduction

The Vigneron is an early Cold War era sub machine gun of Belgian origin. It was developed by Belgian army colonel Georges Vigneron to equip the post World War 2 Belgian army.

Design

The Vigneron is a blowback operated sub machine gun that fires from an open bolt position. The design includes various elements from earlier sub machine guns, most notable the tubular receiver, hinged dust cover and wire strut retractable stock of the M3 Grease Gun. The magazines and magazine housing are patterned after the MP40. The ribbed barrel and ported muzzle seem to be derived from the M1928 Thompson sub machine gun.

Firepower

The Vigneron fires the 9x19mm Parabellum from a 32 round detachable magazine. It is a select-fire weapon with ability for semi-automatic fire and full automatic fire at 620 rpm. The fixed sights are zeroed at 50 meters. Maximum effective range is 100 meters.

Users

The Vigneron was developed for use by the Belgian army. These guns were used extensively in the conflicts in the Congo. Portugal also adopted the Vigneron and various batches were sold to African nations. In Belgian service the Vigneron was replaced by the FNC assault rifle in the 1980's and 1990's.
