Chatellerault Experimental SMGs: MAC48 & 48LS

Published on June 12, 2023
Duration: 10:04

The Chatellerault MAC 1948 and 1948LS were experimental French submachine guns developed post-WWII, aiming for modernized small arms. The MAC 1948 featured a simple blowback action, MP40 magazine compatibility, and a wooden foregrip. The 1948LS was a lighter, simplified version with a wire stock and folding magazine well, inspired by the M3 Grease Gun. Both were rejected due to design flaws, notably the manual dust cover, leading to the adoption of the MAT-49.

Frequently Asked Questions

What were the Chatellerault MAC 1948 and 1948LS?

The MAC 1948 and 1948LS were experimental French submachine guns developed by Chatellerault in 1945. They aimed to modernize small arms and were part of a design initiative that eventually led to the MAT-49.

What made the MAC 1948 different from earlier prototypes?

The MAC 1948 models shifted from lever-delayed blowback to a simpler, more robust blowback action. They were designed for better handling and shootability, though this increased their weight compared to earlier, more compact designs.

What magazines did the MAC 1948 use?

The standard MAC 1948 submachine gun was designed to utilize standard German MP40 magazines. This was a practical choice in post-WWII France, where MP40 magazines were readily available.

Why were the MAC 1948 and 1948LS rejected?

Both prototypes were rejected primarily due to a critical design flaw: the manual dust cover. If closed during firing, it would cause the firearm to jam immediately by preventing cartridge ejection, making it unreliable.
