The Vigneron M2 features a hooded front sight protector for durability, an open notch rear sight for better target acquisition, and a reinforced dust cover locking tab, addressing weaknesses found in the original M1 design. Many M1s were retrofitted to M2 standards.

Why was the Vigneron M2 rear sight changed from the M1's aperture sight?

The M2's open notch rear sight replaced the M1's aperture sight to improve target acquisition, particularly during movement and in low-light conditions where maintaining a sight picture through a small aperture can be challenging.

How can you identify if a Vigneron M1 has been upgraded to the M2 standard?

Upgraded Vigneron M1s often display a '2' stamped over the original '1' on the receiver. Additionally, they will possess the M2's characteristic hooded front sight protector, open rear sight, and reinforced dust cover locking tab.

What do the 'A.B.L.', 'FP', and 'CB' markings on Vigneron SMGs signify?

These markings indicate the firearm's service history. 'A.B.L.' stands for the Belgian Army (Armée Belge / Belgisch Leger), 'FP' for the Force Publique, and 'CB' for Congo Belge (Belgian Congo), showing its use in various Belgian military and colonial forces.
