  1. air-cooled, fires from a closed bolt, and it hasn't a quick exchange barrel = It's a magazine cook-off waiting to happen.

  3.  @pdalia  ​ The Gewehr 41 was an abomination made in 1941 (so not near the end of the war) that was later corrected by copying the Soviet SVT40 (Gewehr 43). The fact that the Germans (like the Italians, Belgians, Czech and so on) made some good design doesn't mean that they make only good designs. A lot of manufacturers make good barrels.

  4. It's not exactly a competition between the best but, between this and the BAR, this is probably better.

  5.  @nindger4270  Yeah. And magazine-fed LMGs easily overheat if they don't have a quick exchange barrel and several spare barrels. That's why the ZB vz.26, the Bren, the FM 24/29, the Breda 30... all had a quick exchange barrel. That's why the BAR overheating was a common occurrence in WWII (but there the open bolt action at least avoided cooking-off an entire magazine) and that's why the Swedish added a quick exchange barrel to the BAR to make the M/37 LMG.

  6.  @nindger4270  Unfortunately, as said, the BAR stopping working in action due to overheating was a common occurrence in WWII. Maybe they didn't see the same people (see, for example, Robert R. Hodges Jr., Robert R. Hodge "The Browning Automatic rifle" p.42).

  7.  @ineednochannelyoutube5384  It' hasn't. No barrel change that requires to open the receiver and extract the bolt is considered "quick".

  8. It's not easy to strip a gun of 2/3 of it's weight. It's easier to design a new one.

  9. That was the MG15.

  10.  @Jargolf86  The Breda 30 was surely slower reloading, had a more open shroud and a ridged barrel to aid cooling and, after the first battles, it was seen that its two spare barrel provision wasn't enought, and it had been increased to four. May be this barrel could resist a little more than that of the BAR (whose overheating was a common occurrence in WWII despite the open bolt that at least avoided the cook-off of an entire magazine), but it could surely overheat.

  11. In 1930 quick exchange barrels were pretty estabilished. To not have one in an air-cooled MG that even fires from a closed bolt is a pretty inexcusable mistake. Air-cooled, fires from a closed bolt, and it hasn't a quick exchange barrel = It's a magazine cook-off waiting to happen.

  12.  @pdalia  The Gewehr 41 didn't work that well. Well designed mechanisms work. Ill designed ones don't. Indipendently by the nationality of who designed them.

  13. 13.3kg. It's rather heavy even for a LMG.
