AK-50: August 2020 Update

what is up you sexy youtube mother lovers you've already seen the title so you know what time it is yes you hungry hungry heathens it's time for our mandatory quarterly ak-50 update ak-50 number one all right this is the last test of the ak-50 b1 the bolton carrier actually run a hell of a lot smoother than they did on the v1 and i think it's just going to turn out to be i mean just superior and pretty much all fronts just from cost from manufacturing to to weight so i know what you're probably thinking brandon you're doing an ak-50 update which means you probably couldn't think of another idea for content today could you well right as you may be you inquisitive [ __ ] something actually cool has happened uh fairly recently in the ak50 project that is worthy of an update so i don't do these more often because i don't want to do ak-50 updates because i know they'll rack in those sweet views and oh climb those subscribers but i don't want to just make videos for the sake of saying we didn't forget and we're still thinking about it so i usually wait until something happens or we make a big design decision or parts came in and that's what happened this time hearts came in for the new prototype not just did parts come in that look like the old stuff you've seen before we actually have something kind of new that we've been working on it's pretty nifty and i can't wait to show you guys how it works but first ad time if you're wondering what allows us to keep making parts for the ak-50 and keep doing videos like this it's sponsors like big daddy unlimited big daddy unlimited i feel like i'm contractually obligated to say is like the costco of the gun world you guys got mad at me last time i forgot that basically it's an online subscription service where you could sign up under my code of course in the description and in the pinned comment and you can get exclusive deals on ammo guns accessories pretty much pay to get it at dealer pricing at least here in the us guns and ammo and whatnot are really starting to get hard to find like it's it's really drying up with all the uh stuff going on see youtube i didn't say it they still have some stuff in stock though so if you want to go check them out the link is in the description and in the pin comment they're a huge support of the channel so i did want to thank them very much and after you go sign up for them we can get back to the ak-50 stuff he's supposed to so what we're going to be talking about today is the rear trunnion now if you don't know what the rear trunnion is on an ak let me show you excuse me while i just pull an ak out of my ass so the rear trunnion is this piece here these uh two rivets uh right here on the akms it's two long rivets 74 style or 100 series stuff you have two short rivets and one long rivet there in the top rear but what the rear trunnion does on the ak is it holds the stock to the receiver it is what you screw the stock into but it does a little bit more than that it also holds the recoil spring so you see up there the recoil spring is locked in into this rear trunnion as well as being the stopper for that bolt carrier so if this carrier uh cannot go too far this is basically just a piece of steel in the back that as the recoil spring slows it down at the very end can smack hold of the rear triangle stops it from going too far or becoming a projectile and enlarging your eye holes prematurely prematurely as if there was a proper time to do that so outside of the gun we actually have an akm rear train here this is what it looks like you have like i said two long rivets here that go all the way through the only thing long rib means is that it goes through from one side of the receiver to the other and you kind of crush the rivet instead of against one side of the receiver and one piece of trunnion you're crushing it in the middle of two pieces of receiver so theoretically stronger yeah nothing too crazy akm or trunnion now what i'm going to show you next is a pkm rear trunnion now pkm or the pikm is a 762 by 54r big boy heavy duty machine gun you've probably seen it in modern warfare or whatever it is you kids are playing these days but it's a big boy machine gun been serviced a little while in one of the later designs of mikhail kalashnikov as you can see there's a pretty sizable difference between the two although i will say that this one looks a little bit beefier than it really is because these are tangs these are stock tanks this is where the stock screws into but this part here this is the beef of the rear trunnion the part that actually does the job of you know being the backbone of the gun making sure that the bolt and carrier don't as i mentioned before projectile through to the shooter's shoulder which is kind of a feature so here's your pkm rear trunnion let me introduce you to the prototype ak-50 rear trunnion this thing's [ __ ] huge almost dropped it that is a beautiful beautiful piece of machining i feel like people forget the scale of the ak-50 sometimes they feel like it's just make make ak longer and put 50 cal in it with barrett mag no it's not quite that simple otherwise i would have done it three [ __ ] years ago akm rear trunnion ak-50 rear trunnion i know what you guys are thinking and trust me i've been thinking the same thing damn boy just now let me explain some of its features so what we actually have here is a two piece assembly so we have the main meat of the rear trinion where we have one two three four five long rivets that go all the way through and are countersunk to hell for extra strength we have these side slots here that are actually going to be for a prototype sheet metal receiver or stamp receiver like we talked about the last update we are going stamp on the new prototype just because we feel we feel like we can and i just think it's going to be really cool to have the akm-50 right so the rails are going to fit right in under there and of course that's where it's going to be riveted to the receiver when i say rails by the way i mean the curved uh top pieces of the stamped receiver itself it's where it's going to fit in there quite nicely i hope so what we have here in the second piece is the part that the recoil springs actually fit into so as you see here this is where kind of in like in past models we have a dual recoil spring assembly where we will sit our ak style springs right there next to each other and uh something neat that we were kind of experimenting around with is having a buffer system in the rear trunnion of the ak-50 where the 50 bmg has kind of a wide range of loads where you have you know your standard ball you have maybe your hotter stuff your hunting loads your hornady amax you have all sorts of stuff ralphus rounds if you're a g like that but you could be running standard ball ammo and then run heavy heavy uh you know supercharged loads or you could be running with a suppressor there's all sorts of stuff and yes you can run 50 bmg suppressed i've done it it's rad there's all sorts of variables that make this thing very prone to potentially over gassing or at least having gas issues what we kind of came up with was a system where we have a floating rear trunnion here that fits in its own little channel it's actually really cool because there's not a lot of side to side play in this as it is but with that rail there it's going to sit in the same rail as the bolt carrier does and so it's going to be riding right alongside of it so as it sits in its forward most position and the bolt carrier comes back i have a 3d printed model here the bolt carrier comes back and hits it it's going to ideally if it's gas properly just barely kiss that and then go back forward into battery but if you are running it hot you're running it suppressed you're running it basically you're over charging the gun instead of just smacking the rear and beating the [ __ ] out of gun out of the gun and then reducing the service life or potentially causing issues there's all sorts of nasty stuff that can happen what we're going to have is basically a second spring in the rear that is you know a lot tighter a lot more aggressive than all right let me rephrase that so you're going to have a tighter wound spring right back there it's actually going to be on kind of a buffer like a stem in the middle uh it's going to be a complicated assembly i don't have all the parts here in front of me but we had some 3d printed prototypes that seemed to work pretty decent so we went ahead and have this have this machined but when it bottoms out and it still has more energy like let's say you're running it hot you're running it suppressed uh you're being an idiot with grand pappy's piss and hot reloads this goes all the way back it bottoms out still has more energy left it can go comfortably into that second spring and have a lot more resistance to it so it's going to be fighting it a lot more but it's not just going to immediately bottom out steel on steel and then it can push it back forward and then the gun cycles as it should do we need it i'm not sure am i kind of glad we're working on it yeah i think it's going to be pretty neat just just listen that's that sweet stirring the macaroni sound that your mom and her new boyfriend makes i'm sure you're familiar we had some old prototypes kind of you can see early versions of when we were trying this we originally tried doing the same thing with the spring in the middle with like a t-slot up top kind of like a big ak recoil spring assembly just like the original akm i thought that would be a cool look but it ended up being a little bit more complicated than i would have liked and i just seemed like there's a lot of places where there could be resistance and it's just that and complications and machining i i don't know i i feel like this would have been a massive part to machine anytime you're machining anything out of a piece of billet steel you are required to have a piece of steel on the series special cutting steel for it but generally if you just have a block of steel that is as big as the farthest dimension so instead of having just a piece of steel this thick or a piece of steel this thick you'd have to have a piece of steel that is that thick entirely and just mill all of this away to be able to get to this so it's a little bit more complicated more expensive to machine we figured that this was probably the best way to go about it or at least for now i could be totally [ __ ] wrong but we'll see so this is all pretty much uh ready to go into our new prototype stamped receiver which is is gonna look ghetto as [ __ ] and it's gonna look straight out of fallout but if it works i really don't care it's going to be [ __ ] beautiful to me as far as what's coming next what's next to do uh right now here's our you know like i showed you the 3d printed prototype of the new bolt and carrier assembly just going to have to have this machined i think we're almost done with that got a couple tweaks left to make we're gonna have to send that off to get machine that's why people ask like where's the ak-50 it's like well there's like two or three months at a time hey very expensive to do like this is all this is passion project at this point we have never taken pre-orders on the ak-50 we don't have any gofundme i don't want to do that it's passion project i don't feel any pressure if there's not people that are waiting on you know well i i i paid for an ak-50 or i gave this much money that's why i've never done it uh so i i prefer to keep it that way even if it does lead to a couple of months of waiting around or waiting for parts to come in and such uh kind of like the rear trend assembly but i feel a little bit more relaxed and you'll never get an ak-50 if i [ __ ] die of a heart attack before we ever get there you laugh i've been close so but next up is the bolt and carrier assembly we're going to get this machined and from then on i think after we we rivet our front trunnion assembly which you saw again previous videos uh we finish our stamped receiver uh we rip it in the rear trunnion assembly buffer assembly and get this new thing ready to be installed honestly i feel like we might be able to have that gun functioning fairly soon it's just we're moving at the speed we can get parts in is what it comes down to but i hope you guys genuinely enjoyed this long long video of just me rambling about machining and 3d prints and parts and showing you light machine gun parts and just generally talking nonsense i showed you my light machine gun please respond but yeah hopefully a lot of you guys that are interested in the weapon design portion of this the guys who are just interested on the status of the ak-50 project hopefully this was cool for you guys i know it's cool to me i don't get to work on this stuff very often i've got the company side of things they're running the business the doing all the content on youtube and i love it to death this is the stuff that i really like working on so anytime i get to come around and talk to you guys about this it's where my heart's at so i enjoy it anyway guys that's pretty much it yeah i guess i will talk to you sexy youtube mother lovers in the next video thanks guys [Music] the bolt has gone forward the weapon has fired
