Frequently Asked Questions

What is the historical origin of the MAS-45 rifle?

The MAS-45 originated in 1945 when French forces occupied the Mauser factory in Oberndorf am Neckar, Germany. They utilized Mauser's existing .22 training rifle designs, like the KKW, to create a new trainer for the French military.

What are the key differences between German and French production MAS-45 rifles?

German-produced Mauser Mod 45 rifles typically have a blued finish, oak stocks, and a 66cm barrel with a left-hand twist. French-produced MAS Mod 45 rifles are often parkerized, use beech stocks, and have a 61cm barrel with a right-hand twist.

How is the bolt disassembled on the MAS-45?

The MAS-45 bolt is removed by disengaging a release lever on the receiver. The bolt itself can be disassembled by removing the firing pin retaining mechanism, allowing the firing pin and spring to be withdrawn from the rear.

What caliber is the MAS-45, and what was its intended purpose?

The MAS-45 is chambered in .22 Long Rifle and was designed as a military training rifle. Its robust action was even considered capable of conversion to higher-pressure cartridges.
