大家好,歡迎回到《這是什麼武器?》 我是Jonathan 你應該已經看過我幾遍了 你知道這東西是怎麼用的 我覺得這是個好玩的武器 因為它有點普通 但同時也有點不一樣 它是一個鑰匙 你可以看得出來 非常有特色的設計 鋼鐵接收器 滾輪延遲操作 H&K稱之為滾輪鎖 所以它只需要把釦子和釦子鎖上 只需要鎖上 用一對很細心的 精心設計的滾輪 然後它就會開啟了 然後就開啟了 你知道怎麼鎖上 如果不知道怎麼鎖上 我會在以後的影片裡解釋 這是非常普通的 MP5 G3 HK53 556的MP5 和HK33 這兩款武器的整個家庭 時間表 1980年 1985年 HK33在製作中 已經一年多了 有人 有原因地 把鋼鐵接收器 完全拆除 並且不斷安裝 一顆一半能力的 鋼鐵接收器 所以它是來自 Shteyr AUG 一顆一半能力 不斷安裝 沒有任何更好的 更強的 它只是來自鋼鐵 我們已經有足夠的進步 我們正在嘗試使用 標準的鋼鐵接收器 在80年代 但是它不像今天 我們只要安裝鋼鐵 鋼鐵沒有H&K的優勢 你可以看到 這裡和這裡 兩側 這是H&K的鋼鐵接收器 讓你安裝 各種不同的鋼鐵接收器 在某些方面 可能不是最新的步驟 但至少鋼鐵接收器 可以安裝ACOG 或者EOTech 某些現代的鋼鐵接收器 鋼鐵接收器還有PICATINNY 增加重量 增加高度 例如鼻子提高 所以很奇怪 舊式的H&K 是更加的大眾化 更加實用 但來自那段時間 70年代到80年代 我們有科技 來提供低能量的鋼鐵接收器 所以有些人 也在做這件事 H&K也做過 這不是H&K33 讓我來 示範一下 H&K33 如果沒有看過 它是5.56毫米 這兩個 沒有祕密 這就是H&K33 沒有鋼鐵接收器 有點奇妙 其實不是太奇妙 我在想 為什麼要用 H&K Diopter Round site protector Front post 可以換 如果需要 Drum rear Open rear notch Quick acquisition Hundreds of meters Small aperture Each time you turn it Excellent iron sights Basically everyone says so It's a little bit of a head scratcher As to why It's getting toward the end of the useful life Of the HK30 In a way it's a heyday Some countries were buying the HK33 Rather than the AR15 For reasons Probably a familiarity With the G3 Older HK Systems 1985 HK introduces this new GR range I actually don't have a note Of what the GR1 was But the GR2 Is the HK53 But with a fixed optical sight GR3 Is what you see in front of you The GR6 is the HK13 Machine gun And the GR9 is the HK23 I have been sent some Snaps from H&K USA Thank you very much Of the brochure of the time For this GR series I think it might even cover other variants We only have the GR3 Ours is curious as well Because it doesn't have A colored or camo finish The hallmark of the GR series As advertised Was not black And yet ours is There is quite a bit of mystery around this What was the impetus For this specific rifle So as I say it's an HK33 Grind off the iron sights And Stick on a One and a half power optical sight Just to show So the only difference here In the lower receiver The trigger group Ignore that That's just a progression over time During the 1980s They gradually swapped over They are actually available at the same time For several years This version with the ergonomic With the finger bumps And the thumb ridge Sorry, thumb ridge on this side And this weird shape And the SEF markings That continued until I think at least the year 2000 But then in parallel to that The HK33 Did get upgraded With exactly the same style of plastic Both plastic but polymer But with slicker sided And with A selector either side So for either left or right And with the pictograms And certainly in this case It's the no bullets One bullet, three round burst And then all the bullets So it's a fully selectable Fire control group Which I think was standard on the GR series What the heck does GR stand for? Well, the official H&K book From Kirsten and Schmidt Tells us that it stands for German Rifle Which I laughed out loud at When I read it In the book Now, why would a German company Call a weird spin-off Of the HK33 The GR3 I don't entirely know But it seems that it was Either there was an impetus from a foreign contract And Peru has Bought 200 of these Maybe it was them And or It was a marketing thing Someone had a brain wave And decided to rebrand German Rifle Instead of Heckler & Koch But they kept up the Heckler & Koch names HK33 etc In parallel So this is where I'd like to briefly pause And remind you that we really do appreciate it If you subscribe to the channel Liking is also good But if you subscribe That really does benefit us We do know that there are a lot of people Coming in and watching some of our videos Without being subscribed So we're reaching more people That's great but we want to keep them too So please do like and subscribe So let's get rid of this HK33 Before we do though I actually would like to share with you A cool point about it It's actually marked Although it's German proofed It's marked EN33 Some of you are thinking I think I know why And you'll find MP5s with EN And HK33s If I remember rightly That is an Enfield assembled HK33 So this was a little bit of a wheeze Whether the German government Was able to permit Export of H&K firearms Not from Germany By the UK And that's as much as we're going to say about that one So let's move that away Let me just Ram home the fact that this is If that is a ground off Casting and forging Of the front Standard HK front sight Unit They've done it really well You can't really tell Hard to say Engineers or production engineers Would you do it that way Or would you create a whole new item Not really my area And then we've just not welded on The sight unit To the receiver there The sight itself is obviously the thing that's different Let me show you the markings first I've just done that on the 33 So it is marked GR3 It has a serial number in the 3- Range Now that style of serial number Usually denotes a model So presumably 3 stands for That specific GR3 Model Maybe for the whole range But I suspect not I haven't been able to lay hands or eyes On any others to confirm The ones from Peru Have a totally different marking system Other examples are Sanitized effectively of markings Don't tell you what they are Or what the serial number is Which is interesting I've also been told by somebody that would know That the actual impetus for this Or perhaps what they redirected it for Having already come up with it As a way to try to sell rifles And machine guns to someone else Don't know But one of the reasons for this Was for police marksman It's very hazy But either they came up with the idea Of this fixed 1.5 power optic For their series of rifles For police marksman And then in parallel develop the GR series Or some permutation of that I don't know At the time The buzz was that HK Had developed this To replace the iron sights Specifically for police Now until the 90s Select fire lowers on a police firearm Would not be uncommon Equally you could order it with Whatever you like So there may be a police marksman element to this Because more accurate fire At maybe 100 meters Is basically what police marksman do The optic itself It has this polymer housing There is a sort of What appears to be a sighting groove In the top of the Molding There's no way to use it as a sighting groove Because this rubber protective End cap and this rubber eye piece Are taller than the groove So there is no way To actually sight down the groove However if you Bring it into the shoulder And look over the top of the sight I suspect it's meant as a sort of Shotgun rib style instinctive Aiming tool To help you align Because you've got this thing in the way The bore of the gun as it were That would give you a line To point at the enemy If you have to shoot over the top of the gun Because when you're in the sights You have no situational awareness Even if you open both eyes It's not ideal Partly why iron sights lasted for so long And why reflex sights for close range Are so popular There's just a crosshair in here I don't know if we can Get in with the camera and show that It might be tricky It's a plain crosshair right in the middle of the Field of view No graduations No aiming devices Or aids in there at all Now it is adjustable So there is an adjustment For windage By means of a tool So right and left That's the correction for left and right So if your sight is misaligned Because it's always going to It's never going to come out of the factory Bang on, you have to test fire And zero the rifle And you can then adjust left or right To compensate for point of aim Versus point of impact With a tool But this wheel at the front If we look at it from this side Is actually marked So just like that drum Is marked in yellow 100, 200, 300, 400 On the 33 That's this on 1 100 meters Click to 2, 3, 4 And it's going to be Impossible to show you In camera as it were But that will raise the reticle To bring the point of aim up Because you're effectively Lofting your bullets in Even at that relatively close distance Only a laser is as flat shooting As that You still have to correct for hold over Now you can obviously do that manually By simply knowing where your Bullets are going to go and aim over But most sighting systems Do include a way to adjust your sights Or a way to Graduation To be able to hit To lift Lift your sights, lift your muzzle as well To shoot accurately So Yeah, interesting So the actual body of the We can't get into this To see exactly how it's attached But there must be Interesting point If anyone knows or can figure out How exactly this is attached To the top of the receiver Normally it would be seen welded on there But clearly not There is a casing over the top I cannot Immediately see How this would have attached Once it's on there, you don't care You're leaving it on there and if it breaks You send it back to H&K We are not going to risk prying at this To get under the polymer casing There is a notch here That looks like it might Allow removal The manual does not cover disassembly There would be A specific armorer's manual For disassembly Disassembly of the rifle Not worth doing It's exactly the same as everything else Magazine works exactly the same way You can get the nice big 40 rounders For these It's sort of a combination of a rock and lock And an AR You can essentially just insert But you have to do it at an angle And that's your magazine release This is all standard H&K stuff Including the solid buttstock If you're thinking That's a different design to the H&K 33 It's not. They changed over time They've reverted to the earlier shape In order that the buttstock Doesn't affect this eye cup So it sort of is different But only relative to this later style Trigger group So they've gone with They've upgraded this to the current style They've gone back in time a few years To the earlier more streamlined style So the buttstock less robust In order to be able to accommodate This eye cup So there are a couple of details like that But otherwise it's a stock H&K 33 Why didn't they just call it H&K 33 O for optical sight or something I don't know I just say It's clearly a marketing thing Whether it involves police Or foreign militaries or both One last thing I decided to dig out the manuals Because we're very fortunate to have A GR3 manual, an original one And the H&K 33 In this case E manual Which is the export model Which is kind of what this is But it's marked as an EN 33 And if we turn to a random page I mean there's a general There's a good general description there And you can actually see Although it's a black and white image You can probably see that they are camouflage Colored There's a sand color There's a forest camo pattern And those have their own suffixes As well within this range So the general description differs Well no, sorry The pictures differ The name differs And nowhere does it say German rifle It just says automatic rifle Capitalized GR3 caliber 5.56 Blah blah blah That is identical To the opening blurb In the H&K 33 manual The automatic rifle H&K 33 E caliber 5.56 Blah blah blah Absolutely the same The images are With the exception of the update Of the trigger group And the buttstock shape Also the same It's a different format of manual So they are differently arranged on the page But it's the same They've recreated the exact same image And the more modern H&K 33 manual Would have the same photo So no different The only difference Comes with the 33 Having a section On optional An optional optical sight Using that claw mount That I mentioned Only gives that style of optic But others would have been available And it explains how to use The iron sights as well Whereas the inverse is true Of the GR 3 manual They've removed the pages on the iron sights And inserted Literally a page I think Let's find it Here we are So it's actually a double page But only because there are images They just inserted the instructions On how to zero the sight It's pretty easy to use It doesn't tell you how to shoot With that reticle But that's for a training manual Rather than a user manual Which is what this is So we're quite pleased to have this Bit of archival or ephemeral Whatever you want to call it History to go with our single rifle Which is weirdly black And not camouflage coloured or sand coloured A bit of a footnote in H&K's history But I think an interesting one Because it's a stepping stone Between the iron sighted rifles Of yesteryear and today's rifles Where they often do come with no iron sights And the option to fit A sight of your choice But the GR3 You're stuck with this Thanks so much for watching everybody We really do appreciate it Do remember if you're not already subscribed Hit the subscribe button And of course we always appreciate a like click as well Goes a long way And you can come and visit our real life museums If you'd like to do that We also have If you'd like to see these videos Without advertisements You can go to Or download the app or go to the website History of weapons and war And a lot of the other Firearm and military history based YouTube channels Are also over there With something extra to offer you Whether that's no ads or even extra content In some cases as well So please do go and check that out See if it's something you'd like to sign up for But you'll always be able to see The videos here for free See you again next time
