  1. Cobalt, chromiun, tungsten steel alloy. Heat and wear resistant, but difficult to machine. Industrial cutting tools are made of that.

  2. Actually it worked pretty well.

  3. Infact that was the intended tactic. Any member of the squad is a LMG gunner if he's in the right position. First he covers the others, then someone else covers him.

  4.  @ForgottenWeapons  No cylinder is completely sealed. Both the one of the AR and the one of the Rasheed are exactly as sealed as it's requred for the action to work. Had the diameter of the "open gas tube" of the Rasheed been a little more closely fit with the "cup", that would have made it a "not true gas impingement rifle"? Mind that many true gas piston actions had not that much sealing of the piston (IE the piston of the M1 Garand is a simple button), because all that sealing is not required for the action to work. And the AR15 works without gas rings either. The sealing is not required for the action to work. They are there only to mantain the action cleaner.

  5. The "accuracy" thing is just a mith (Carcano, iron sights at 1500m https://www.youtube.com/watch?v=KA5xmQGZHc4 ) . Reload is faster with en-block clips than with stripper clips, and already in 1905, examining the battelfields of the Russo-Japanese war, Władimir Fiodorow (the future designer of the Fiodorov Avtomat) noticed that, in mud and snow, Manlicher actions tended to be more reliable than Mauser actions (the passing of the clips and the bottom hole kept the action cleaner).

  6. In the '80s selection for the 5.56 NATO rifle for the Italian Army, in the end, the AR70/90 competed with a AR15 derived rifle, the SOCIMI AR831. However the AR831, like the Daewoo K2, replaced the direct impingment with a long stroke gas piston with an AK-syle recoil spring over the bolt, so to use a folding stock.

  7. That was probably the problem. In late '80s no patent on the "92" expired yet, even on the original 1976 model. So the designer had to walk around any part of the 92 that was patented.

  8. Nothing had been "screwed up". The weapon had been higly successful, so much that the Austrians copied it, double barrel, tripod 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 develop the OVP18 and the MAB18 (that were 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.

  9. All the M38 and 91/38 short rifles have the lateral front and rear sling attachments. The sling of Owsald was not an original military one.

  10. Dictatorships tend to build crappy armies, because to control population only needs an army at the minimum level of efficiency, while the army is the only real threat for the dictator, so resourcefulness of the officers is actively discouraged, yes-men are promoted, and a lot of the armed forces' money is spent in bribes.

  11. There had been two separate issues. A pair of cases on the SEALs 92SB, and yes, that was due to very high round count and firing an unprecised mix of ammos. Then on some Army M9, tested for endurance in 1988. 12 had been tested. Generally they reached a very high round count, but a pair of them had the slide cracked at low round count. Initially the Army determined it was due to the steel alloy of the slide, requested it to be changed, and Beretta modified the slides so that even a cracked one could't be projected out of the gun. However Beretta technicians were not persuaded. They were selling 92 series guns to military and police forces all over the world, and only the M9 of the US Army seemed to have problems. They analysed the results of the test, and noticed all the low counts slide cracks happened only when a single batch of Federal Cartridge ammo was used. Once tested by independent labs, it was determined those rounds developed pressure in excess of proofloads (Beretta sued the US government at that point, and the lawsuit was settled with them receiving further $ 10m). Ironically, the 92 remained known for the "slide cracking" problem, while, at that time, its slides were arguably more robust than those of any Browning design competitor.

  12. The Carcano is loaded with en-block clips. You slam the six rounds in the rifle WITH the clip. The Lee Enfield is loaded with stripper clips. You insert the cartridges in the rifle FROM the clip, but not WITH it. That requires more time.

  13. In the mid '80 industry had switched to metric for designs for decades. To submit blueprints in imperial was really backward, especially coming from young engineers. That partly explains the mistakes (even if we don't know how big they really were). To have to convert was no more common.
    2
  14. It has been "proven"? LOL!
    2
  15. Here's the patent. It's called an "expander lock". The lever locks the bolt like a chair put at an angle under the door knob. In theory there's no limit to the power of the ammunitions this gun can use, as long as the frame is strong enough. https://patents.google.com/patent/US461968A/en

  16. Field strip. To have access to the gas chamber and the gas ports (that's the thing that requires cleaning, there is not actually much that could happen to the piston and op rod) you only have to remove the muzzle cover. To inspect the recoil spring, you can remove it from the trap door. To remove the bolt you only have to remove the dust cover and the rear buffer ("when the dust cover is off, it just slides out") and it comes out from the rear of the receiver. The thing can be field stripped in seconds without tools, that was not a given at the time.

  17. It's not from the '80s, it's from the '50s. In the '80s Bernardelli produced the very good P0.18 ( https://www.gunstorebunker.com/wp-content/uploads/2018/10/BERNARDELLI-P018-MIL-1.jpg ).
    2
  18. Nothing fancy. The same than using proofloads on 9mm guns. The gun worn out quicker.
    2
  19. Field stripping it is EXTREMELY simple. Much simpler than field stripping a M1 Garand for example. 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.

  20. They were too stupid to even copy. The FG42 derived bolt suffered of chipping locking lugs (the armorers were supposed to stone them. Yes, your locking lugs are falling apart, stone them) because the locking lugs were smaller than the original ones and cut at a straight angle, while the original ones, cut sligtly angled, didn't slam metal on metal on closing.
    2
  21. Infact. The Germans gave away almost for free rifles that they would have not used anyway (except in very dire situations) because they were early iterations. A pragmatic approach.
    2
  22. The first samples were real rifles, in 6mm Flobert or .22 Short. Then it was deemed too dangerous, and they were made blanks. Germans simply had less time to evalute the incidents (Hitler came to power later), or cared less.
    2
  23. The Beretta 1915 started in 9mm Glisenti. The .32 ACP model was still named "1915", but it had ben done only in 1917.
    2
  24. It does.
    2
  25. They developed a pneumatic fire rate reducer (rallentatore di tiro Pavesi) that reduced the ROF selectively to 500 or 300 rpm.
    2
  26. Only if you can make the job done with a single magazine. if not, With the Beretta you can carry far more rounds for the same weight, and change magazines much faster.

  27. The ballistic of the 7.62X51 was a false target. The 7.62x51 was a very good design for the time for it's intended purpose. It's ballistic couldn't be replied by a round without making it uncontrollable in full auto (apart for the engineering marvel that was the 7.92X41 CETME). It was a question of deciding what they wanted. Or full auto controllability, or long range accuracy and power.
    2
  28.  @2Potates  You can exactly reply a 7.62mm ballistic with a 7mm bullet having 20% less recoil and overall weight of the cartridge. But the fans of the 7.62 will always say that the heavier bullet will have better penetration against hard materials and pierce bigger holes into soft tissues.

  29.  @lardomcfarty9866  I've seen people complaining about the holder "looking down the barrel without checking" because the gun was pointed towards the camera.

  30.  @AbitantedelVault  Le Breda 37 e 38 erano considerate "eccellenti" nei report alleati, non si capisce cosa avrebbero di "antiquato".

  31. You can buy a gun of your choice, you know?

  32. Italy is the second industrial powerhouse in the EU. When Germany wanted to lift the lockdown, German car manufacturers advised Merkel that they couldn't resume production, because italy was still in lockdown, so they could not receive the Italian made parts of their cars. "some Beretta products are acceptable"? Ask to the Argentine outfitters, whose shotguns fire thousands of ammos a day with sketchy mainteinance, what shotguns they rent, to make sure the customer doesn't have to stop hunting due to a jammed or broken weapon. When there is serious work to do, there is one shotgun manufacturer. The others are amateurs.

  33. The 7.62 NATO had been designed after WWII exactly because modern powders allowed to replicate the performances of the 30-06 Springfield in a MUCH SMALLER case. The 7.35 Carcano had to use a 1891 case with a 1891 designed action made for 1891 pressures.

  34. This is the father of the Walther.

  35. Glisenti M915. Hotter than the standard pistol Glisenti M910.
    2
  36. The S has some change over the previous model. The combined safety-decocker feature, different lenght of the levers, and the separated plastic grips instead of the one-piece wooden grip.

  37.  @hannibalkills1214  I know what the point of the Gurttrommel was, and that it was better than a dangling belt, BUT IT WAS WORSE THAN ANY MAGAZINE ANYWAY, the Guttromel was a "necessary evil" to use a belt-fed MG as a LMG, but to use a belt-fed MG as a LMG was a sub-optimal solution. "an established position to provide covering fire"means that the MG is no more a LMG but it became a fixed-position HMG. It's not how it works if the squad is moving. It's fire-move-fire-move-fire... One of the most common WWII picture is the German machinegunner with one or two belts over the shoulders "el frito bandito" style (they decided that, compared to the guttrommel, the dangling belt was not that bad after all), but it was certainly not an optimal solution. 50 rounds in the MG42 are 2.5 seconds of fire regardless if they are fired continuosly or in short bursts. No "training" of the soldier can change the mechanics of the MG.

  38.  @hannibalkills1214  "not advance in the same rate as the riflemen" doesn't mean he can stand in a fixed position to consume a 300 round belt at will. Reality doesn't work like that. US Army experts, analysing WWII infantly clashes, noticed that riflemen tended to gather around the BAR and the BAR was almost always the weapon that started the fire exchange. And US GIs were armed with M1 semiauto rifles and carbines (while the BAR was a suboptimal LMG), not with almost useless bolt action rifles.Yet the difference between the squad automatic weapon (20 rds) and the semiauto rifle (8 rds) was enough that the movement of the BAR dictated the movement of the squad. If the MG is slow, the squad is slow. I know the lafette mount, and you certainly know it was not always possible to use it. That's why the MG42 has a bipod as well. 2.5 seconds of fire at 6 seconds interval is reasonable. 3 seconds of fire at 2 seconds interval is better.

  39. There had been several. Korth, H&K P9, Geiger GRP... Germans seems to be particularly attracted by roller-delayed mechanisms.

  40. "not designed here"
    2
  41. During WWII, and after, they manufactured fuses for artillery shells.
    2
  42. A machinegun that shoots pistol ammunitions. The Italian and German definitions ("pistola mitragliatrice", "machinepistole" so "pistol-machinegun") are more fitting.
    2
  43. The locking mechamism is unusual in it's operating principle, but the pieces are pretty simple to machine. The frame is actually stamped, so the simplest it can be.
    2
  44. A minority of them is caused by the design. IE, as said, the BM59 is a copy, not even a Beretta original. The jamming is caused by the fact that the Garand barrels they used had several gas port sizes, from .95" to .120", but in a BM59 configuration a gas port below .110" is not enough to cycle the rifle. In the Breda PG, and several others antiques, the problem likely is a worn out magazine spring, that doesn't lift the next round fast enough. Those magazines were not made to be used for decades.
    2
  45. All those pistols, like the Bernardelli P08, and this one, have the half-cock position. That's what was intended to replace the decocker, as, if you hold the hammer, pull the trigger, allowing the hammer to just slightly move forward, and release the trigger, the hammer will safely seat in half/cock even if you suddenly release it. From half-cock, the first double trigger pull is more pleasant too (same weight, but shorter pull).
    2
  46.  @Cyan_Nightingale  "much better" in respect to what? The BM59 was not adopted without competition, see the Franchi LF59, that in itself would have been an outstanding battle rifle, easily on par with the FAL and G3. The BM59 won because it was not inferior, thus being (for the aforementioned reasons) more economic. As said, many countries didn't adopt an intermediate caliber AR until recently. The 5.56 NATO cartridge had been standardised only in 1980. Before, it only existed the .223 Remington. A cartridge that the US Army decided to use, but not NATO standard.
    2
  47.  @hendriktonisson2915  The ZB.26 had been tested prior to the adoption of the Breda 30. No army replaces an MG just adopted only because there is on the market something marginally better. All the "Breda 30 bashing" is a modern "internet era" thing. At the time the opinions were MUCH more blurred. Allied reports praised the Breda 30 in comparison to the Bren.
    2
  48. This weapon was not a "last ditch" in the sense of putting the more gun that's possible in the hands of the more peoples that's possible (like the German or japanese ones), It was a "last ditch" intended to be issued to experienced soldiers, only easier to manufacture than a MAB38. The front safety solved a real issue of early SMGs, and had never been a problem in combat situations. The fact that a design is unusual does not mean that's failed.
    2
  49. It's considered a lever delayed blowback. The acceleration of the bolt carrier in respect of the bolt face can be obtained via a lever or inclined surfaces.
    2
  50. +canicheenrage What I meant is: "the water cooled HMGs of the time had the reliability advantage of weighting a lot". As said, they were overbuilt in respect to the work they had to do. The more you remove weight, the more is difficult to mantain the same reliability, because parts become more subject to external factors.
