This video explores two rare French MAC Model 1947 prototype submachine guns, showcasing their innovative lever-delayed blowback action and unique design features. Despite their advanced mechanics, the prototypes were rejected due to material requirements and ergonomics, with the simpler MAT-49 eventually being adopted. The review highlights the prototypes' lightweight construction, folding magazine well safety, and distinct charging handle mechanisms.

Quick Summary

The MAC Model 1947 prototypes used a lever-delayed blowback action, a sophisticated mechanism designed to delay bolt rearward movement until chamber pressure dropped. They featured a folding magazine well safety and unique charging handles, but were rejected for requiring high-quality materials and due to ergonomic concerns.

Frequently Asked Questions

What was the primary action mechanism of the MAC Model 1947 prototypes?

The MAC Model 1947 prototypes utilized a lever-delayed blowback action. This system uses an accelerator lever to delay the bolt's rearward movement until chamber pressure drops, allowing for lighter bolt weights and compact designs.

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

The prototypes were rejected in 1948 primarily due to the requirement for high-quality materials, which increased production costs, and issues with ergonomics. The simpler and more robust MAT-49 was eventually adopted instead.

What unique safety feature did the MAC Model 1947 prototypes incorporate?

Both prototypes featured a folding magazine well that also served as a safety mechanism. By folding the magazine well, the magazine was moved out of alignment with the chamber, preventing accidental discharge.

How did the two MAC Model 1947 prototypes differ in their design?

The prototypes differed mainly in their stock design and charging handle mechanisms. Prototype No. 02 featured an under-trigger-guard charging handle and a stock folding over the receiver, while Prototype No. 01 had a Sten-style folding stock and a side charging handle.
