This guide details the field stripping process for the rare MAC Model 1947 Prototype SMGs, as demonstrated by Ian McCollum. It covers the removal of the bolt assembly and recoil spring, highlighting the unique lever-delayed blowback mechanism. Proper safety precautions are paramount during disassembly.

Quick Summary

The MAC Model 1947 Prototype SMGs, developed by Châtellerault (MAC) in France, feature a unique lever-delayed blowback action and fire 9mm ammunition. Despite their light weight and compact design, they were rejected in favor of the simpler MAT-49 due to manufacturing complexity and ergonomic issues.

Frequently Asked Questions

What is the operating system of the MAC Model 1947 Prototype SMG?

The MAC Model 1947 Prototype SMGs utilize a lever-delayed blowback operating system. This mechanism uses an accelerator lever to delay the bolt's rearward movement, allowing chamber pressure to decrease safely before extraction.

What caliber ammunition do the MAC Model 1947 prototypes fire?

The MAC Model 1947 Prototype SMGs are chambered for 9mm ammunition. They were designed to accept modified MP40 magazines, typically holding 32 rounds.

Why were the MAC Model 1947 prototypes ultimately rejected by the French military?

The MAC Model 1947 prototypes were rejected in 1948 due to the need for high-quality materials in their complex lever-delayed system and concerns about ergonomics. The simpler, more robust MAT-49 was preferred and adopted.

What are the key visual differences between MAC Model 1947 Prototype No. 01 and No. 02?

Prototype No. 02 features an under-trigger-guard charging handle and a top-folding stock. Prototype No. 01 has a more conventional side-mounted charging handle and a Sten-style folding stock.
