[HOW TO] CYMA CM.041SD6 DISASSEMBLY - parts inspection

[@taxman121]

Great video! I have had a Cyma MP5 SD6 for a little over a year now. Performed great until two of the bearings in the gearbox blew up. Everything else looks fine. Took it apart to figure out what was going on. This video will help so much with reassembly.

[@felix427leecrouch8]

You're missing the adjuster tab for the hop up. It allows access to adjustment from the bolt cover.

[@gen-zboomer]

One thing that's cool is that you could totally buy an A2 styled stock, put it on, and simply disconnect the front wiring adapter since it's not actually a whole ass wire running along that thing! This thing looks so much easier to take apart than my AK lol

[@ArchieKeen1]

Another note about those cyma v2 gearbox’s is they use v3 spring guides from the looks of it which is nice as they are designed way better than v2

[@Angrypanda68]

Another solid video ...glad we found the hop adjuster although from the other comment posted it maybe broke...will be good to hear Taiwan guns reply re that . Was a little disappointed at the compression but that's is easily fixed ..always amazes me how complicated these are to take apart compared with the real steel versions 🤣

[@PheasAirsoft]

It surprises me erveytime that the real steel counter part is easier to work with ha ha ha.

[@Andrew-uv5qy]

I had a Cyma Mp5k a long time ago and i remember that the hopup had a little arm that continued inside the handguard. I don't know if it is the same system but I'm pretty sure there is a problem with your hop up because it looks like it actually misses something. I don't think the allen screw was put in the box for the hop up adjustment. Anyway, it looks a great replica. Peace.

[@gm_construct8024]

I have an mp5 a5 and i didnt knew how to dissasembly it, thanks!

[@callumbiasnow4825]

Really useful vid. I got 041j version last year and had to watch a French vid to work out how to strip it (and I’m crap at French) so this is amazing. I’d love to see a vid of what you’d do to upgrade this gun as I’m a beginner with no idea where to start.

[@thomasegeberg3464]

Hey awesome video - do you have any ideas as to how the suppressor can be taken apart? i would love to make mine a tad shorter, thank you in advance!

[@PheasAirsoft]

Hiya! I think just violence, as it is glued from what I remember. Pheas

[@chaskascl]

good video, there is not spring around the inner barrel ?

[@PheasAirsoft]

Hiya. Usually not on an mp5 as the hop unit isnt secured against the front of the body it's usually screwed down or the gearbox is forced up against it so there is no need for one. Pheas

[@chaskascl]

@@PheasAirsoft thanks!

[@terry85t81]

Hi pheas. For this gun is it gate Titan v2 front wired ? Can do away with that section of the loom running along that channel

[@tynce563]

Super helpful videos. You’re the best mate!

[@The_Mexecutioner]

Wow, I was thinking about buying this gun, but after seeing that hop up I don’t think I will.

[@tylermellor8369]

There is supposed to be an arm that goes back to behind the bolt on the right side where he was adjusting it with the Allan key. His seemed to be broken and missing which is a common issue if you do the Mp5 slap

[@kevinnguyen8498]

I know this is an old video, but was the from of the gearbox radiused in front of the cylinder? With it being the common point of failure in V2 gearboxes, I know that radiusing that section eliminates that problem. Curious to see if Cyma has been doing it or not.

[@PheasAirsoft]

Hello! Its hard to see, but the shell has been radiused to prolong the life span of it. Hope that helps. Pheas

[@hal752]

About to order one of these. Plan is to change the barrel so it reaches the end of the surpressor and change out the bucking. General shim and regrease. Do you recommend anything else?

[@PheasAirsoft]

Hiya. Sounds like you have most of it covered. If you are running a 7.4v then I would switch the motor out for a high speed one. The Kublai one is excellent! Pheas

[@hal752]

@@PheasAirsoft I was going for the high speed one which comes with a high speed motor. Most likely il be wiring up a xasr mosfet or some aab mosfet to run 11.1v.

[@tomkarlsson1]

Got one of these yesterday. Your hop is definitely missing its adjustment-arm, its supposed to be a standard ak-hop and the arm on mine is clearly visible when you pull the tab back as on any rifle

[@PheasAirsoft]

Cheers for this. I managed to find images online to show that it was missing an arm to connect to the hop. Emailed Taiwan gun now so hopefully they will sort something out for me. Pheas

[@GalaxyZi]

is it possible to get CM.041J BLUE LIMITED EDITION and to get parts somewhere to convert it to CM.041SD6 version and where could i get the parts if at all possible

[@AZSP1966]

Shame about the hopup adjustment access I certainly won't be buying a CYMA MP5SD6. On the Elite Force Competition edition it has a VSR10 style hopup adjuster on the top left side of the gun but it's made mostly of inferior polymer so I passed on that model also.

[@PheasAirsoft]

Hiya. It turned out that it was missing the part and Taiwan gun supplied me the part needed free of charge, its the first time I have ever had that happen with an aeg before. Pheas

[@dannybartoschek7904]

Hi there, just quick question, is it possible to dissassembly the silencer in order to put custom filling?

[@olescuandrei1555]

If you look closely at the front of the supressor, you can see a seam, so most probably it can be unscrewed to fill it with foam or with some modding put a tracer unit.

[@pyrexxdj]

is there a fast spring change system or do i need to disassemble the whole replica like you did

[@PheasAirsoft]

You will have to disassemble the whole thing unfortunatly! Pheas

[@DEADEYEAIRSOFTPH]

Very nice partner, big thumbs up.

[@joshsilk1680]

Where do I get the tab that stops the stock sliding out from. I need one

[@sgt.miningdrill2680]

i was fixing my 8 years old RPK puting M130 spring back was pain

[@cameronmcelwee5465]

I have this same gun and the hop adjuster is accessed just by pulling the charging handle back. It's a forward/backwards adjuster. Not sure what happened with yours?!

[@PheasAirsoft]

It was missing the arm that allows the adjustment. I spoke to taiwan gun and they sent me a full replacement hop unit to sort it! Pheas

[@pedh6806]

I was wondering why you were having an issue. I have the same gun and it's no problem. However with the adjuster arm missing it makes sense. Your disassembly vids are very useful. Rebuilt My g36c gearbox using your vid as my guide no problem. Thank you.

I will be doing the disassembly of the AKM (filming it) today or tomorrow. If you drop me a message on Facebook, insta or my email I will send you a link to have a look at when it is uploaded. Pheas

[@IratusSerpentus]

I wonder if it would be possible to machine the attachment point for the suppressor to be 14mm threads and still usable with the original

[@PheasAirsoft]

I think that's entirely possible, as long as you don't mess with the pegs coming off the sides of the outer barrel, or at least leave the bottom part of them, the rest could be machined to 14mm negative thread. Pheas

[@Burumkiller]

Hey Pheas i just got the mp5 and when i shoot the gun the bb hits supressor at the end and the bbs go 20 30 cm to the right (depends onds the distance) have you heard about this problem and do you have a fix for it?

[@PheasAirsoft]

Hello. First thing I would do is twist and remove the suppressor and check it's shooting straight without it on as could be a barrel or hop issue. If it's shooting straight, then make sure the suppressor is secured fully down, if that doesn't work, especially if it's band new, I would send back. Pheas

[@Burumkiller]

Me and my friend ordered the same gun and he has the same problem

[@andrijakostic837]

Can you unbox the cyma cm 518 and review it? Sorry for bad English

[@PheasAirsoft]

@@JinceofVoy if it's the same type, and doesn't have the quick change spring system, then it will be a full disassembly. Pheas

[@DutchessNDukes]

Hey Pheas, I have a question. Is the suppressor hollow, so I can put a tracer unit in there?

[@PheasAirsoft]

Hello! Oh man that's a good question.... I seem to think there was foam in it , but you could open it up, probably fit a tracer insider it as well.... You might need to wrap something around the tracer to keep it centralised though, depending on the tracer. Hope that helps. Pheas

[@isaacshively6705]

Put a full stock on it, the SD5 is the best looking MP5

[@PheasAirsoft]

I'm all about the retractable stock personally. But I can see what you mean. It does look awesome with the full solid stock. Pheas

[@iSkateAlso]

Would the disassembly be the same for the bolt sd5 variant?!

Are they 7 or 8mm bearings? Wondering of the gearbox shell is the same as the blue edition

Hiya. They are 7mm bearings in the shell. I think it is the same gearbox but an uprated motor that they have included in it. Hope that helps! Pheas

[@tomhewitt8017]

@@PheasAirsoft great thanks! Would you recommend changing from bushings to bearings? Any good brands? I've found a few online but no idea what makes are decent Great vid btw, just bought the blue edition and looking to make it a bit snappier. First time airsofter and I didn't know the high speed edition was a thing until after I ordered it lol

[@PheasAirsoft]

@@tomhewitt8017 That's a good question with the bushings and bearings. With bearings they are in theory not going to last as long as bushings as they are a moving part so will at some point fail, but they can help to make the gearbox turn over that little bit snappier. So if you wanted the best rate of fire out of it then I would consider going down the route of bearings. If you were building a DMR build I would recommend the bushings in stead of bearings as they will stand up to the pressure of it high fps better. If you have the MP5 and want to make it a little snappier, a quick, relatively cheap upgrade could be a high speed motor, they range from about £25 to £80 (sometimes more) for a motor and can transform your rate of fire and how snappy the trigger is out of the box with little effort. I have been trailing the Kublai one from taiwan gun in my KWA Tk45C division 2 and it has been immense, the rate of fire has shot up loads! So maybe not rush to the internals if you can help it, and have a look at other areas to win on first. Hope that helps Pheas

[@tomhewitt8017]

@@PheasAirsoft thanks for the advice, that awesome. I'll take a look at shimming and a motor upgrade :) think I'll go with bearings. Snapper would be better and I'm only running the gun up to 350 fps one last question, do you know which motor is currently in the blue edition?

Weird about the hop. I have an old CYMA MP5 EBB were it has an extended hop adjust arm. The arm runs along the gear box and is easy to get to with the mock bolt open. You use your finger nail to slide it back for more hop and push the arm forward to lessen hop. The adjust arm is small but is reinforced by resting on the gearbox. Weird how they went away with that arm.

[@PheasAirsoft]

Hiya. In the end it was wrong. It should have had the adjustment arm. I contacted Taiwan gun and showed them the video and they confirmed it was missing the part. So they sent me a full replacement hop unit! Which I was pleased with. It was the arm that ran along the side of the gearbox. Pheas

Hiya, does the selector go to each of the selector positions properly? It could be that the cam on the inside isn't lined up with the selector plate properly. Or it could be that your cut off lever which pops the trigger when a single shot has completed isn't seated right maybe. If it had single shot before then more likely to be something to do with the selector stuff. Let me know how you get on checking those first. Pheas
