Frequently Asked Questions

What was the primary role of the MAS 49-56 rifle in the French military?

The MAS 49-56 served as the standard French infantry rifle from 1956 to 1979. It was designed as a versatile platform capable of functioning as a standard infantry weapon, a grenadier's tool, or a marksman's rifle, notably featuring 22mm NATO standard rifle grenade launching capabilities.

What are the key differences between the MAS 49-56 and the earlier MAS 49?

The MAS 49-56 features a shortened barrel and stock for better maneuverability in modern combat environments like vehicles and helicopters. It also incorporates a gas cut-off system for safe rifle grenade launching and uses a NATO standard 22mm launcher, unlike the MAS 49.

What safety concerns are associated with the MAS 49-56 and modern ammunition?

A significant safety issue arises from using modern commercial ammunition, which has softer primers than the original military issue. The MAS 49-56's original design lacks a firing pin spring, increasing the risk of slam fires. Aftermarket titanium or spring-loaded firing pins are recommended.

How does the MAS 49-56 handle rifle grenade launching?

The MAS 49-56 is equipped with a gas cut-off lever that prevents the bolt from cycling during extreme pressure events like launching a rifle grenade. It also features dedicated grenade sighting hardware, including a flip-up sight and adjustable range markings on the barrel.
