The complexity of the action system is a reminder of the trade-offs in firearm design, but it's a testament to the innovation in post-WWII France.

[@andersjjensen]

And let's not forget that the SMG to rule all SMGs, the MP5, is not a simple blowback gun. The guys who worked on this one clearly knew what they were doing. I imagine the recoil impulse on these wouldn't be too far off the sensation the roller delayed system provides. And even as an undying MP5 and G3 fan I must admit that this system looks more gunk resistent.

[@TeletubbiesRcute]

It's really not that complicated

[@andersjjensen]

@@TeletubbiesRcute Obviously not. But it is still more complicated than a one-piece bolt and a spring, as is what is needed for simple blowback.

[@lukaszpokoju]

Looks strangely similar to the Walther MPL which was developed only few years later. Despite the MPL using a much simpler simple blowback system, there are many odd similarities between the two, like the overall shape, grip angle, bolt architecture, charging handle location, the MPL even has a notch on its front sight protector, just like on the front sight post of many French guns of this era. Probably just coincidental. I believe the Walther MPL is in a way, what the MAS 48 could have become, in the event it would have gone through longer development ( removing the complex delayed-blowback system, replacing grip safety/ double trigger selector, by a selector switch, improving the stock design, using stamped steel for the upper and lower receiver).

My Grandpa was Canadian born by Breton parents. His family went back to Brittany, France in response to the great depression of the 1930s. In the time before he was old enough to enlist as a soldier for WW2, he and his brothers spied on roads for the French Resistance. He enlisted at 17 for the French Army and served until 1950, deciding to move back to Canada in 1955 and start a family. He would end up having a family of 6 kids. I always wondered what types of fire-arms he might have handled/relied upon and your videos have really helped give me a better idea of that, thank you!

These are some long barrels for an SMG. They are pretty interesting, but indeed look rather expensive compared to other SMGs, I'm glad the concept was recycled for assault rifles.

[@raifsevrence]

These are such cool looking guns. The way the mag well folds up with a mag in place is a very interesting feature. Couple that with the folding stock and you have a fantastically compact package for transportation. Love the operating system too. Shame these never got adopted. Looks like a much better platform than the MAT 49. The MAT 49 seems to have taken the grease gun school of cheap as possible, but still functional design and won out by appealing to the government's wallet. That and I'm betting it weighs several pounds less than these MAS 48's.

[@adamkaneshiro]

i think some manufacturer used a similar concept with a glock pistol where the grip/magwell hinged and made the pistol more compact

A great very interesting video and French experimental smg.Have a good one Mr.GJ.

[@Getpojke]

Really interesting. Was there a specific designer or Government/Military, order/edict that sent the French down this route of having ultra compact folding sub-machine guns? I can see the purpose of wanting them small for stowage/transport, especially for paratroopers on in battle taxis. But I sometimes wonder if it was any quicker to engage a folding magazine & well compared to slamming a magazine in place & start firing/having a safety catch in place for a loaded mag? A folding magazine well also seems a natural weak point that could cause feeding failures to me. It does however make them very cool & Heath Robinson (Rube Goldberg if you're American). It just seems that they were designing heavily towards a predominance of paratrooper or sneaky covert use, when for much of their service life most sub-machine guns would be carried ready to use. (Maybe just the old case of "the French copy no one and no-one copies the French!?) Then again I suppose the French Gendarmerie/Gendarme regularly carry sub-guns & it makes them easier to carry without appearing overtly offensive in public!? Thanks for the video, I found it fascinating to see this amazing collection of splendid guns.

[@johanmetreus1268]

Ease of carry also transfer into ease of storage. Short racks and compact crates that makes logistic transportation more economical. Folding magazine well means you don't have to start the process retrieving a magazine from your webbing, which was a far cry from the speed access oriented webbings of today. Their main purposes was to 1) make sure the magazine wasn't lost when crawling and jumping around, 2) prevent dirt to ingress) and 3) prevent damage to them. If that meant secured protected flaps delaying the shooter half a minute, so be it.

[@Getpojke]

@@johanmetreus1268 Yeah, I can see those points being very much part of the design ethos. Maybe just an evolutionary blind alley in gun design, as they're features we rarely see today apart from some very specialised instances. So maybe they weren't worth the drawbacks in the long run!? So saying things like folding/sliding stocks have become common & mag placement in things like to pistol grip/bullpup/longitudinally (eg P90) all can help make things more compact or shorter on Submachine guns & PDWs. But finding that perfect layout while keeping things compact still seems to be a white whale.

[@johanmetreus1268]

@@Getpojke Goatboy, I'm not sure that the design meeting a dead end as much as simple mass-produced submachine-guns not having much value in a world where you can get a five and half mm (5.45 and 5.56) carbine relatively cheaply and in about the same size. As to why we don't see folding magazines on carbines, I think it is because the form factor of magazines today. The SMG-magazine were very long and thin, so you save a lot of space that way. Now most use carbine length of intermediate cartridges, and the more square shaped rectangle doesn't make that much of a difference. So yes, that White Whale is still out there.

The long barrel version would be awesome in .30 Carbine.

[@notadorf]

a somewhat similar prototype in .30 carbine did exist except it's roller delayed, it's called the ceam modele 1950, notice how this gun has a similar look to an hk g3 because it was "co-developped" by captured german engineers after the second world war. it was a whole branch of research on delayed blow-back mecanism.

[@donjones4719]

Is the ejection port dust cover automatically kicked open when the bolt slams forward? That's a feature I've long thought would be a good one. On pretty much every SMG I can think of, once the bolt is cocked back the ejection port is open. Someone crawling forward on a rainy muddy day will have his weapon cocked. The cocking handle incorporates a cover and the folding mag well seals the gun in either position. This SMG seals up better than any I can remember.
