  1. Handguards were an early phenolic resin/Bakelite. There were some prototypes with carbon fiber, but the ones in the video are Bakelite.

  2. Bolt and carrier weren't made from stainless. They were 8620 IIRC, definitely hard chrome plated. The Dutch did an excellent job on the metallurgy of the AR10, as well as attention to detail. The ejector pin is chamfered, for example, to help prevent case head impingement in the bolt face from the right side feed presentation from the magazine. They are fine rifles when you look at the workmanship on them.

  3. Excellent video. I just purchased my first M28 recently to go with my Hayha Plaque, which has one of the spent casings found in the early 2000s at one of Hayha's firing positions when members of the Finnish sniping community went to interview Hayha, and were asking him specific questions about the battle of Kollaa. He said, "Why don't we get in the car and go there and I'll show you?" When they walked to one of his positions, dudes started kicking around in the grass, and found lots of spent cases. "I guess those are mine." He had been allowed the rare opportunity to work autonomously by his Company Commander, who was a veteran of the French Foreign Legion after being kicked out of one of the Finnish Officer's Training Academies. We find that the extreme cold conditions of Finland and the region are great at preserving war material even dating back to the 1930s. Buddies of mine have found Russian and German soldiers, complete with kit, in frozen graves that thaw out in the few months of summer. One particular site outside of Sainkt Petersburg was a treasure trove of German paratroopers and their FG-42s.

  4. Mine is a M28/30, not M28.

  5. I would also like to see a Thompson vs. PPSh-41 2-gun match. That would be sick.

  6. Simo was a competitive rifle shooter before the war, and mastered shooting from positions.

  7.  @6.5mm_is_the_best_mm  Yes. As volume increases with projectile travel, pressure decreases. I've been involved with pressure measurement systems for quite some time now in a professional capacity.

  9.  @6.5mm_is_the_best_mm  We've all heard about primer jump where the high explosive of the primer causes enough pressure to jump the projectile into the lands, after which the propellant column is ignited and peak pressure is reached based on that new slightly larger volume. Military cartridges often use sealants so primer jump isn't normally an issue in those instances. Most of your slow-burning rifle propellants are burned within the first few inches of the chamber, and the resultant hot expanding gas continues to expand behind the projectile, forcing it down the bore until the pressure is relieved at the muzzle. But I've not seen piezo-electric readings where pressure was lower at the mid-chamber than anywhere else. There is pressure build-up on the time scale, but peak pressure is in the chamber. If you look at the barrel shank of a light profiled magnum barrel, you'll see where the taper starts. You wouldn't be able to start a taper so close to the shank if you still didn't have FoS there, and FoS is determined by pressure.

  10.  @FeatheredDino  The AR-10 has never been as reliable as the AR-15. Jim Sullivan said they noticed that even in the late 1950s, even though the AR-10 came first. It's a totally different animal from an engineering perspective, even though the design layout is the same.

  12. There is one really cool PDW chambered in an anemic cartridge currently that would greatly benefit from this for the civilian market, without sacrificing mag capacity. It would be a game-changer for catching on, but the maker of that PDW would frown on it.

  13. Was the Honey Badger lubed?

  14.  @kyleheins  The common shoulder-fired weapon issued to the vast majority of soldiers in a Line Company should not exceed 5lbs and should not be very long at all. Think M-1 Carbine weight and handling, but shorter, with at least 5.56 NATO performance. For Rifle Squad Leaders and Team Leaders, they should carry a DMR with upper end electro-optics, chambered in an Enhanced Intermediate Rifle Cartridge like 6mm ARC+ in performance, and that cartridge should be common to the Lightweight LMG with linked ammo. Riflemen and Grenadiers should carry the PDW-sized Carbine, as should Ammo Bearers, Assistant Gunners, Anti-Armor Weapons Specialists, everyone in Mortars, CO, 1SG, RTOs, PLs, Drivers, FOs, Combat Medics, etc. A battle rifle cartridge platform should not exist in the Rifle Company other than Medium Machine-guns in Weapons Squads, and those could be replaced with a .338 Norma-like hybrid polymer/steel case to reduce weight, while increasing long range performance. 9-12lb rifles for everyone is a non-starter concept in the year 1960, let alone 2022.

  15.  @dasboot9471  M14 was a huge failure for a service rifle by purposely ignoring every hard lesson learned in The Great War, WWII, and Korea. The Army already knew this prior to any major force commitments to Vietnam after conducting combat studies with it vs units with AKs at Fort Benning in the early 1960s. Basic load was too small, too heavy to sustain the fight, resulting in dudes getting run down/maneuvered on.

  17.  @kyleheins  You can have a 5lb empty carbine that smokes armor at close range with AP. 6lb with optic, 7lb with full mag. With an intermediate cartridge, you can match or exceed the terminal performance of 6.8 NGSW just by going to a smaller diameter bore pushing a 135gr with much higher BC. That would give you a DMR slightly larger than an AR-15, not as big or heavy as an AR-10. Army had the false premise that the projectile diameter must be .277", which is really backwards thinking, but at least smarter than requiring 7.62mm. Basic load sucks though, can't carry a reasonable load even without armor. With armor, it's a non-starter.

  18.  @kyleheins  Most dudes in the line don't need anything like this, and can have a carbine that weighs less than half of this, while delivering impressive performance. You can have a sick integrated electro-optical aiming system without it being so huge and bulky as well, for an overall weight with loaded mag under 7lbs.

  19.  @kyleheins  You can have almost everyone carrying lightweight carbines that will smoke armor within 200m using AP. MGs and DMs can carry something faster.

  21.  @redwolfexr  What law? ATF rulings aren’t law. It’s not my job to fix them, only exercise my rights per the supreme law of the land that supersedes any confiscatory or criminal conduct by a Prohibition-era gaggle of criminals who wear suits. I have no legal responsibility to correct an illegal agency in the manner you seem to be suggesting. Not sure what you’re referring to with “your movement”. I’m just a man with a family who exercises our rights.

  22.  @redwolfexr  11 years of "skirting around laws"? There are millions of pistol braces, 10-40 million as of 2021, per Congressional Research Service 2 years ago. The 2nd most common handgun caliber purchased in 2020 was 5.56mm per NSSF industry statistics provided by manufacturers. Will not comply with ATF excrement rulings.

  24. They are over-built since Finland can't afford to buy new rifles all the time like in the US.  Steel is 2x as thick on the billet receiver for a very long life.  Finnish conscripts still use Rk62s to this day for their military service-the same rifle many of their grandfathers used in their service.  They can be quite accurate.  They now use polymer mags that were developed with the Rk95.

  25. 605s seem to run fine for me and many others who have them. I’ve shot everything from Wolf to 75gr through mine without a single malf yet, though I only break it out for fun every now and then. 605 should have been looked at more. It’s a handy set-up that offers the best of both worlds. We’re effectively there now with the SOPMOD Block II rifle-length gandguard guns, and now the URGI.

  26.  @hippiesaboteur2556  “CAR-15” was the name for a family of weapons by Colt, to show the modularity of the design for different duty positions and roles. 603 was the Infantry Rifle 605 was the Infantry Leader’s Carbine 607 was the Commando 608 was the USAF Survival Carbine They had a belt-fed light support weapon as well that never went anywhere. The name stuck to the Commando variants that were mass-produced later as the RO619, 620, 629, 630, 639, and 640. XM177E2 was the most produced of those with the 11.5” barrel, same receiver set as the M16A1/Colt 603, 4.5” Moderator. 607 saw very limited production.

  28. The CETME Model 1 was the next evolution of the Sturmgewehr, with a very forward-thinking cartridge capable of close-range fighting with minimal recoil, as well as long-distance effective range that would have been very interesting in a Light Machine-Gun.

  30. The Mafia owned Congress and the FBI in the 1930s, and had every vested interest in protecting the banks as any other huge corporate entity. What really bugged them were the few motorized gangs of the Midwest, notoriously Dillinger's gang, Bonnie & Clyde, and Ma Barker. That's the main reason why the NFA Hearings took place in April-May of 1934. They mentioned Dillinger throughout the hearings.

  31. I'm interested to know exactly which model Thompsons were used by Dillinger (stolen police armory samples) and Capone's Saint Valentine's Day Massacre (1929).

  34. The main reason Army Ordnance finally acquiesced to the adoption of the AR15 was because they saw it as a temporary stop-gap until adoption of the SPIW in 1968. The SPIW concept was the apple of their eye in many respects. Turned out to be a steaming pile of feces.

  36. ​ @truereaper4572 You might want to read Dr. Dolce's protest letter about what was reported to the WC. He was the Chief ballistician at the time at Edgewood Arsenal, where the extensive tests were conducted. They could never get the single bullet theory to work. The Warren Commission selected one of his technicians to present what they wanted to hear, Not what was actually demonstrated in their terminal ballistics testing. Another thing that was omitted was the origin of that ammunition. It was literally a CIA contract to Western Cartridge Company from lot 6000, made in 1954.

  37. ​ @truereaper4572  Read Doctor Dulce's protest letter from Edgewood Arsenal. He was the chief ballistician there who oversaw the 6.5 Carcano ballistics testing. They shot goats, human cadaver wrists, chest cavities, ballistic gelatin, the whole 9 yds. They disproved the single bullet theory. CE399 also isn't he bullet found on the floor at Parkland. It couldn't be identified by building superintendent Tomlinson, or chief a personnel O. Wright. Wright said it was a pointed Spitzer bullet, not a round nose. You run into this kind of stuff at every turn with the WC.

  38. Yup. There have been serious talks of a new assault rifle since the 2000s. It got more serious in the 2010s. Funny thing I noticed right away was that almost every Finn I know in the Reserves already had an AR-15, and many had AR-10s in the 2000s.

  41.  @jbloun911  AR-18 was meant for poor countries who were still using sheet metal stampings for receivers, with trunnions for barrels. Very flimsy weapon nowhere near as reliable or accurate as the AR-15.

  43. ​ @user6008 You realize there was no GSW entrance in the back of JFK's neck, right? There was an entrance lower on his back, below the scapula, right of the spine (doesn't align with the GSW in his front throat). Gerald Ford had this evidence edited & misstated in the WC to help Arlen Specter with the Single Bullet Theory. The M91/38 Carcano carbine was a planted piece of evidence, using Lot 6000 WCC ammunition to steer investigators towards the Cuban ex-pats. That ammo was CIA contract through DoD to Western Cartridge in 1954. WCC never made it before or after, and it has never been explained how Oswald obtained it. See the Edgewood Arsenal ballistics tests for the WC, and chief ballistician Dr. Dulce's protest letter.

  44. ​ @Caeruleo One office worker saw him on the 2nd floor before the shooting, as did Dallas Police officer Marion Baker, 1min 37sec after the shots were fired. Marion Baker ditched his motorcycle on the street and rushed the TSBD looking for any possible suspect.

  45. ​ Oswald had already eaten his lunch. Several TSBD workers had been flooring the 6th floor. Bonnie Ray Williams ate his lunch, including a chicken bone sandwich on the 6th floor in the Southeast window and smoked a cigarette, which was why the window was open. Walter Cronkite said that the sniper was so cool and calculated that he ate his lunch in the window before assassinating the president. The WC then chose to structure the witness testimony to make it seem like Oswald could have slipped by everybody on the 5th & 6th floors, both going up and coming down. They had to go through all kinds of gymnastics to place him on the 6th floor in order for the foregone lone gunman theory to work. Read the WC. It contradicts itself as a rule.

  46. The M91/38 Carcano tested by the WC was 5" right and 8" high.....at 15yds. WC said it had automated moving target lead accidentally built into the zero, which helped Oswald make his shots. This is erroneous because time of flight is maybe 0.1 sec at those short distances. Still very hard to shoot movers, but doesn't require pulling lead. Carlos Hathcock and the other senior Scout Sniper Instructors were unable to duplicate the shots at Quantico's combat village site.

  49. I think the Fort Benning studies with 7.62 NATO rifles vs AKs would have the same results. Anyone bringing the limited capacity of a 7.62 NATO rifle to the infantry fight would have died in place at the hands of OPFOR carrying 30rd mag-fed assault rifles. Qualification scores would likely have been lower with the T48 due to the vertical stringing, although maintenance might have been easier to do for the soldier and armorers, with a lot of cross-pollination between Canada, UK, and other NATO partners using the same system. In the end, the failures of battle rifles in the post-WWII era would have still been a major complaint within the US system, and the likelihood of a SCHV rifle could still have been the outcome. The question I have is would SCHV have been a thing if we had adopted an intermediate cartridge like the .280, allowing more magazine capacity in smaller space, fulfilling the traditional US rifleman institutional culture vs the maneuver warfare assault troop. It would be interesting if they had conducted the same infantry MTO&E and tactics study with 7mm intermediate vs the AK with OPFOR. Even more interesting would have been a Stoner design in 7mm intermediate cartridge with at least a 25rd magazine. I still like the AR15 design of them all, having used all of the rifles mentioned.

  50.  @TEAserOne  I've lost track of how many different types of full auto weapons I have fired, most of which have been in the military or militaries of foreign nations I was working with. When you shoot a constant recoil system, it feels like a dream because the gun barely moves and you're able to continuously place fire where you want it. Normally, machineguns of all types are somewhat hard to control and not as fun.
