The Madsen light machine gun is note-worthy for several reasons – it was the first military-issue light machine gun developed and it was successful enough to remain in production into the 1950s (long after every WWI-era machine gun was long out of production). It was also one of the most usual machine gun mechanisms ever successfully designed – one of the early “what if we try this?” sorts of mechanisms that actually worked quite well. You probably saw the video of me running a Madsen in a 2-gun match last week, and the reason I actually had the gun on hand was to do a more academic video on its history and function. So if you have always been confused about that the heck is going on inside that mechanism, grab a cup of coffee and let me walk you through it:
FYI, my mistake in the tripod shooting was that I mounted the barrel support backwards. It has a spring assist built in to dampen recoil, but it only works one way. I should have noticed the big engraved arrow directing which way to mount it, but I didn’t (whoops).
We have a bunch of documentation on the Madsen on the Madsen LMG page in the Vault, which you should take a look at if you would like to read more.
Since I know people will mention it, the most recent use of Madsens in an organized combat capacity is with Brazilian police in Rio de Janeiro. There are a couple clips of them on YouTube (I’ve downloaded copies of these, so if they ever disappear from the web I can upload them myself). I take no responsibility for the cheesy background music, though:
