  1. Beretta regularly sells the ARX-100 in Italy, and there is a rich choice between AR15 derivates anyway.

  2. 1:11:19 I have to disagree. During WWI France, in a partially invaded country, manufactured more than five times more Chauchat than UK manufactured Lewis Gun (262.000 vs 50.000). Maybe in a 1 vs 1 the Lewis Gun was a better LMG (even if it had its issues. It was more an ambush weapon, apt to be fired from an at least partially protected position, than real portable automatic fire), but 1 vs 5, no way.

  3. The Finns actually worsened the sights, asking for them to be zeroed at 100m instead of 200m before the rifles being delivered. That way they were practicaly useless past 150m, well into combat distance.

  4. The weapon had been higly successful both in the defence and attack role. So much that the Austrians copied it, double barrel, bipod and all. At the end of the conflict a total of 14.564 MGs had been produced (so, more than 29000 barrels, VS only about 5000 MP18), and 836 millions of 9mm Glisenti rounds for them. Mind this. THERE WAS NOTHING BETTER AROUND. When the guy with the Villar Perosa, after having thrown a couple of offensive grenades into the enemy trench to stun the enemies, came over the edge with the SMG in his hands to clear it, he didn’t find the guy with the MP18 waiting for him. Because there was not any MP18, or anything similar. What he had in his hands was incredibly better for that role than anything the enemy had. After having adopted the Villar Perosa, the Italians took almos three years to adopt the MAB18 (that was nothing more than a single Villar Perosa barrel mounted on a Moschetto TS stock) not because the Villar Perosa was unsatisfactory, but because it was so satisfactory that none felt the urge to modify it.

  5. Mind that the 6.5 Swed., until 1941, used round nose bullets whose performances were practically the same than the 6.5 Carcano (156 gr bullet at 725 m/s vs. 162 gr bullet at 700 m/s). Also the spitzer adopted since 1941 was pretty far from modern 6.5 Creedmor performances (140 gr bullet at 800 m/s. A carcano load launching a 140gr spitzer would obtain similar results). Modern reloaders push the cartridge to the limit, or even overload it.

  6. Actually Frommer managed to create the simplest long recoil action possible. Yes, it's still a little more complicate than a Browning short recoil, but not that much, and it has the advantage of a very low bore axis. Unfortunately he made it for a .32 round that could have been fired by a blowback handgun of the same weight, or even lighter.

  7. German engineers giving lessons on simplicity? LOL! Have you seen the bolt of an MG34? Is made of 28 parts, only the bolt! This one is made of four parts.

  8. Kasserine Pass?

  9. When talking about a semiauto shotgun action borrowed to a carbine, it has to be taken in account that the semiauto shotguns' gas actions are the most "battle proven" actions existing. The shotguns rented by the Argentine outfitters, for example, fire thousands of rounds a day, every day, with sketchy manteinance at best, and using cartridges that are far "dirtier" (it's inevitable, due to the rapid loss of pressure in the shotguns' barrels) than any commercial bottleneck round. All that ridges on the piston and the guide rod are not there for show. They are meant to keep the metallic surfaces clean from the debris of combustion in conditions where a typical "tactical carbine" action will get stuck every few hundreds rounds. To use that action to fire .223 Rem rounds is even an overkill.

  10.  @Tirak117  The "heat extraction thru metal cases" had ALWAYS only meant "in respect to caseless ammos". Caseless ammos are ineherently hotter than brass ammos, because the burning powder is in direct contact with the chamber (that's physically part of the barrel obviously). Here's the opposite. Plastic shields the chamber from the heat of the burning powder MUCH better than brass. Heat remains in gasses (that expand more, that's why they need less powder for the same muzzle speed) and it's expelled from the barrel with them, because also gasses are very bad at heat transfer. Plastic cased ammos actually heat up the weapons MUCH LESS than brass ammos.

  11. It's Korth.

  12. The fluted chamber was patented by Giovanni Agnelli (the owner of FIAT car brand) in 1915 for the Fiat-Revelli machinegun (altough not used, since it wasn't really needed in that design). Infact, when the Soviets reused the concept in the '30s called it "Agnelli device".

  13. Then the 9 soldiers came under fire from a PKM on a tripod over a km afar and discover not only their assault rifles, but also their SAW firing from a bipod, are as useful as blowguns.
    2
  14. The Marine Corp adopted the M9A1 actually. Some special unit was given that Colt, without any competition, mostly due to Gen. William M. Keys connections, and had little else than just problems with those. That's why it had been replaced after only four years of service.
    2
  15. The FBI adopted the 10mm for a short time, but had soon to move to lighter loads, and then they replaced it with 40S&W, that had the same load they were using, but, being shorter, could be used on standard 9mm frames. It was not a question of small hands. it's a question that agents are not gun enthusiasts. When the 10mm was adopted, the FBI standard issue was the 357 mag revolver, but much agents, with permission, loaded them with .38 Special +p ammos, because they didn't like to train with the 357 mag. That's the problem. When you adopt a round that's uncomfortable to shoot, agents reduce the training time to the bare minimum, and that degrades their performances on the field much more than the more powerful caliber can enhance.

  16. Actually it was exceptionally sturdy. In respect to water-cooled, breechlocked MGs there was very little that could break.
    2
  17. At 500m a FMJ 9mm Luger projectile can still pass completely through a human body, even more a "9mm M38" cartridge (the super hot 9mm cartridge developed for this SMG) that, at 732 Joule (124grains, 428m/s) power wise was in 357 SIG territory. It's true that it's more difficult to aim a 9mm carbine in respect to a full size rifle due to the more arched trajectory and shorter sight radius, but this SMG can fire in full auto remaining stable, so the possibilities to hit and kill, or even better seriously wound, an enemy with a short bursts were not that low.
    2
  18. All the gas system (gas port, gas piston, gas cylinder, op-rod, a spring in case of short stroke) is replaced by a single adjunctive part, the lever.
    2
  19. For the same reason none did. The FG42 is more complicate than issuing every soldier with a LMG. The competitor of the BM59, the Franchi LF59, had a tilting action similar to that of the STG44, but, being a modification of the Garand, the BM59 was much cheaper to produce.
    2
  20. A double actiion weapon, carried with one in the chamber and the hammer down (condition two), doesn't need any safety. It fires when you pull the trigger. A SA weapon, before firing, needs or to pull the slide (from condition three), or to rise the hammer (from condition two) or to switch out the safety (from condition one). So at least another action that, in a stressful situation, can simply be forgotten (and it happens MUCH more frequently than one tend to think).
    2
  21. The "single lug rising block" locking system is the same used in the Breda M37 and M38 HMGs, Breda 20mm M35 and Breda 37mm 37/54 automatic cannons (altough those listed are practically scaled-up versions of the same weapon, while the PG had several differences). They were all higly regarded.

  22.  @eloiseharbeson2483  More than they taught Physics and basic grammar in your evidently. For the second, I said "MORE similar", and there's no doubt than the 8mm Roth-Steyr is MORE similar to the performances of the .30 super Carry than the 7.65X20 Longe. You can check the meaning of "MORE". For the first, muzzle energy is 1/2massXsquare of the speed. .30 super Carry 100gr, 380m/s, 470Joule of energy. 8mm Roth Steyr, 116gr, 332m/s, 409 Joule of energy. It's not that much of a difference, especially considered that the speed of the bullet, for a given pressure tend to increase linearly with the reduction of the mass, while the energy increases with the square of the speed, so, with a 100gr bullet, the 8mm Steyr Roth would develop more energy. Also 45.000 psi is not "three x" of 21.500. So your elementary school was not that good for math as well it seems.
    2
  23.  @eloiseharbeson2483  Because you should be someone "who knows more"? Without understanding basic math, physics or even having really learnt to read? You are a blatant example of the Dunning-Kruger effect, aren't you? I already told you what the performances of the two cartridges are. It's not my fault if common pistol cartridges' performances in general have not increased much in the last century. It has to do with human anatomy. 8mm Roth Steyr was nothing exceptional in 1908, like .30 Super Carry is nothing exceptional now. As for "knowing so much about the performance of .30 SC", I don't know much. I only know a little more than the "nothing" you do. I just cared to know enough about ballistic to understand what I read and, knowing enough about ballistic to understand what I read, I can explain you (or better, I can explain. Unfortunately you can't comprehend) WHY having more than doubled the case pressure in respect to the 8mm RS resulted in a so meagre increase in the performances of the .30 SC, when the external dimensions of the cases are so similar. Do you know what's the difference between a 21500 psi case and a 45000 psi one? Brass thickness. But increasing the brass thickness of a rather small case, you significantly reduce the internal volume, and that hampers the effect of the increased pressure, because the initial spike in pressure decreases more rapidly as son as the bullet starts moving.

  24. Yeah. It seems you can recollect all of them holding a glass.

  25. air-cooled, fires from a closed bolt, and it hasn't a quick exchange barrel = It's a magazine cook-off waiting to happen.
    2
  26. It takes much more time to overheat, and can't cook off an entire magazine anyway even if it does. This is not a battle rifle, but a lighter BAR. Also the machining required was not that much. That of the receiver is comparable to other semiauto rifles of the era (not to say of light machine-gun). The bolt is made of only five pieces, an only has straight cuts.
    2
  27. Striker requires less parts. The trigger group is simpler. On the other hand, for the same weight, it delivers less energy (it accelerates for a shorter distance) so it must be heavier and use an heavier spring.
    2
  28. Patents on industrial designs last for 14 years, extendable to 21. So they expire pretty fast.
    2
  29. the look is clearly inspired by the SIG P220, and quite different from anything 1911ish. At least anything 1911ish that was available in the early '80s.
    2
  30. Because they didn't want to make it blatant that the rule was intended only to make the .45 ACP (or better, the 1911) to remain relevant in the competition.
    2
  31.  @hailexiao2770  But less projectile choices and probably more resistance to be adopted. Better sectional density is really significative only past 300m, and the US infantrymen didn't (like they sitll don't) train past 300m (then it was 300 yards, 274 meters). Infact, in the end, they adopted the .30 Carbine.
    2
  32. Actually all those were first generation SMGs, while the M12 is a second generation smg (the first second gen. SMG had been the Armaguerra OG-43). The difference is that second gen. SMGs have much of the bolt weight placed in front of the bolt face (because it's "L" shaped or, like in this case, its telescopic and placed around the barrel), so shortening the weapon and making it more balanced during fire.
    2
  33. It's the contrary. Beretta and SIG parted ways because Beretta wanted a AK style action (long stroke gas action, three lugs rotating bolt) and SIG a roller delayed action. In the end SIG didn't manage to make a roller delayed action reliable enough to fire the 5.56 NATO cartridge and ended up making a roller locked gas action for the SG530. After the market failure of the SG530 SIG adopted a bolt nearly identical to that of the AR70 for the SG540.

  34.  @CreedManiac99  To move by bicycle and with a gun in the pocket was pretty common at the time for middle class men. And bar brawls that ended up with a shooting were common too.

  35. Benelli B76. It has an unique push-type (the trigger pushes the transfer bar, like in a SA pistol) DA trigger.
    2
  36. The "tactical and technical trend" (the magazine of the US intelligence) deemed it to be superior to the BREN in dusty conditions. The oiler was surely a "minus", but it was not the only part of the gun. Other features (IE heavy bolt and plenty of space for the dust to be displaced during the bolt's run) made for a decent gun in those conditions.
    2
  37. They didn't. O = Ordinaria (normal), C = Critica (critical). Like in the selector R = Raffica (burst).
    2
  38. It's a false problem. The barrel is loose only as long as a round is not fired, then the same expansion of the brass tighten the action. Any MG42 and MG3 ever built has a rattling barrel, and none ever noticed this being a issue in 60 years of use.
    2
  39. We are used to see weapons in clips and movies where everything always works just fine but, In WWII it was a REAL issue to manufacture magazines that were so cheap to be discarded on the field and so well and consistently built to not have feeding issues (it's no chance that still the M14 had a stripper clip guide). The BAR and the BREN were plagued by jammings caused by incorrectly built or damaged magazines. In exchange of a little more time required in reloading, the Breda 30 avoided all the feeding issues caused by the magazines.

  40. What shown is not a field strip, but a disassembly of the rifle. A normal field strip (to clean the gas chamber, inspect and maybe replace the recoil spring, clean the bolt and maybe replace the firing pin) can be made in seconds without tools, that was not a given at that time. Like almost every bolt action rifle up to then, and several semiauto rifle after then (See the Gew.43 for example), this rifle is not made to have the trigger group and the receiver removed often from the stock (that's why they are fixed with screws). While the parts that require cleaning (bolt and gas ports) and have to be replaced more often ( almost universally the recoil spring) are very easily reachable.

  41. @ "direct impingment" doesn't exist. Pressure doesn't work that way. The supposed "open tube" of the Ljungman and of the MAS49/56 has an esternal diameter so much bigger than the gas key of an AR 15 (despite the gas pipe being practically equal) because they are pistons, like the piston of an M1 Garand. What pushes the carrier rearward is pressure for surface of the piston. A smaller diameter "gas tube" (mantaining the diameter of the gas pipe, so with exactly the same quantity and speed of the gasses carried) wouldn't have worked, because the pressure would have been there, but not the surface. "direct impingment" is an expression that Stoner used in his patent, referring to the patent of Elklund, to artificially separate that one to his "internal gas piston". But in reality, the only thing Stoner patented, are the gasses in contact with the bolt (while, in Elklund's patent, the gasses are only in contact with the carrier). Both are piston actions.
    2
  42. The shortened case is only required so that the gun will not chamber a 9mm Parabellum round by mistake. It has no relation with the load contained. Power-wise the 9mm Ultra round is in the same ballpark of the 9x20 mm Browning Long, the 9x18mm Makarov and 9x19mm Glisenti. The first two had been specifically designed to be the most powerful load usable in a blowback pistol without weight disadvantages, the third one came to the same result by chance (infact it had been designed for the breechlock Glisenti 1910, but it was then fired by the blowback Beretta 1915 too).
    2
  43. 9mm Largo it's another name of the 9X23mm cartridge. 9mm Lungo is another name or the 9mm M38 cartridge, that's an extra-hot 9x19 mm Parabellum. They are not the same round, and are not compatible in any way.
    2
  44. The lever. It's like a chair put at an angle under the door knob.

  45.  @antoniofdez620  Here's the patent. https://patents.google.com/patent/US461968A/en and a schematic https://ibb.co/NZW8KDm

  46. The Villar Perosa had NEVER been designed for aircraft. Unfortunately Ian's previous video contributed to spread this old tale, but it's evident from all the paperwork, relations, manual, ecc... that it was originally meant to be a field light machinegun. It and had later been adapted to aerial use in very limited numbers, simply because the Army destined the first 350 samples manufactured to the aviation (that was a branch of the Army at that time) because they wanted it to be in full production first to start to distribute it to the troops.

  47.  @buckleyjteams  It has to be said that, while the definition of "assault rifle" came with the first of them to be adopted, that of "battle rifle" is quite recent. It had ben coined in the '80s, along with "scout rifle" and some other. It somewhat stuck, but it's not strictly a military term.
    2
  48.  @GigAnonymous  That was Automatic Rifle. Since there weren't other kinds of automatic rifles, there wasn't need of a specific term for the full blow ammo ones.
    2
  49. The first group to apply the "Assault rifle" label to semi auto rifles wasn't politicians, it was advertisers trying to sell "military style" rifles to the public. Gun Digest even had a series called the "Gun Digest Book of Assault Weapons" which lumped them all in together, further confusing the terms. Gun companies used the terminology also (IE Intratec advertised the TEC-9 as an "assault pistol")
    2
  50. Given the dimension of what this gun is destined to hit, few centimetres to the side makes no difference. The same with LMGs like the Bren. They are not precision rifles, and, to a man-sized target, the effect of the offset is negligible.
