[Set] CM.040 [CYMA] + AK Receiver Cover Rail [CYMA] + Airsoft VZ-1 Style Russian Red Dot Sight [JJ Airsoft]

I was sceptic at first, but you gotta remember that it attaches to the iron sight mount and you can just flip it up if you want to open the dust cover, replaces the shitty original dust cover, i am not entirely covinced it holds the vertical zeroing perfectly, but hey its a airsoft gun.

I bought it for the CYMA AK.048S and With a little violence, the screw fits inside without a problem And it fulfills its task.

For the price this is just insane...
Shipping was very fast and the customer support is outstanding...
Everything on this gun is sturdy...the polymer handguard and pistol grip are of good quality. Most parts are made of steel.
It shoots very accurate at 50m+(i orderd a Maple leaf bucking+Omega nub wich TG installed)

The reshim/grease job is totally worth it.

One of the best AK's out there!
Had a specna arms ak before and the difference is enormous.

The material and finish is nice, feels really good in the hands and there are no wobbly parts. On the field i always say "it's made out of russian tank-steel".

Shoots around 400fps with 0.3g BBs out of the Box, which is perfect for most outdoor fields but a little high for indoor.

It definitely does NOT need any upgrades - works perfectly fine out of the box!- 70m targets are no big deal.

Also this AK is a perfect platform for a nice "modernized" AK or "tarkov"-AK build, as it is compatible with nearly all parts.

If you consider buying an ak74-replica - get this one, you will not regret it :-)

Bought for my CM 031.

Very hard material. Good looking, the rail aligns with the body.

The upper end of the dust cover does not fit to the rear sight of the replica, and had to insert an oval ring to it. After that, it fits well, does not wobble.

...

-good quality

-doesn't fit to cm028

Good quality, at a low price.

-Good quality
-Fits all standard rail accessories
-Low price

-Didn't fit CM.028, had to do a lot of filing.

Spettacolare ! Con una piccolissima modifica calza come un calzino e puoi montare qualsiasi ottica , red dot con magnifer è stabile e per il cambio batteria non hai il problema di dove mettere il coperchio , ottimo rapporto qualità-prezzo come sempre

A very useful upgrade for mounting optics on an AK platform. The rail fits securely, installation was simple, and it provides a stable platform for my red dot sight. The finish matches the rifle nicely and everything feels well made. It has held my optic securely without shifting during use. Highly recommended for AK owners.

Bought it twice, did not fit cyma rpk, that's okay, The cyma RPK fits nothing without modification so I sold it.
Bought it again, does not fit cm.056 which is just a cm.048 with different internals....somehow fits an ancient Dytac SLR AK perfectly.

Fits perfect on double bell ak74 replica perfect fit combined with railed handguard perfect space for battery no vobble nothing would recommend to anyone having a AK replica that would like a reddot holo or anything else 11/10 simply perfect

A must if you want an AK with a slim profile, I've fitted it on an APS AK74 and a Specna Arms AK74M, it requires a little work (for example on the APS I had to remove half a millimeter of material where the dust cover release button fits, but no problems otherwise) Solid fit and the T1 red dot I've mounted on it doesn't go anywhere. Recommended

A great solid red dot for your russian style airsoft replica.
Also props to the service team of taiwangun for the great support.
I received a defect on arrival red dot and they coverd all the shipping costs and deliverd me a replacement one.

Montato su un Cyma platinum, il pezzo si monta abbastanza semplicemente anche se sono serviti un paio di colpi con un martelletto di goma per metterlo in sede perfettamente e consentirne il fissaggio (lavoro comunque alla portata di tutti).
Una volta montato, il pezzo risulta solido e saldo permettendo di usare dot o ottiche in tutta sicurezza.
Lo considero ottimo specie considerando il rapporto qualità-prezzo del prodotto

Nice that the button of the stock has been replaced with a steel one
Mine broke in 3 days without even playing
Dont know where to find a replacement
Other than that its just a plain gun from cyma nothing special its gets the job done

This part fits perfectly on a CYMA AK replica. The fit is solid and secure, making it a great upgrade if you’re looking to improve how you mount a scope on your replica. The installation is straightforward and can be completed in just about 5 minutes. Overall, a very effective and simple upgrade that really enhances functionality.

Feels very solid and is very sturdy. The rail definitely adds some more realistic weight to the replica, i used it on a g&g rk 104 evo, so i had to file down, and adjust a lot of the dimensions, but in other terms, it does the job, and gives the look im going for, overall a good piece for your money! Definitely recommend!

The CYMA CM.040 is a full-length AK74-style AEG that offers impressive build quality and performance for its price range. The receiver, dust cover, outer barrel, and sights are all made of metal, giving the replica a solid and realistic feel. The stock and handguard are made of durable polymer, with a slightly textured finish that improves grip.

Externally, the rifle looks very authentic, with accurate proportions and details that resemble a real AK74. The fire selector markings, rivet placement, and overall finish are well executed. In a proper loadout, it blends in perfectly for Russian or Eastern-style impressions.

The internals are what you would expect from CYMA’s better-quality line. The ver.3 gearbox comes pre-shimmed decently, and the compression parts are solid for stock use. I used a 7.4V LiPo battery and 0.25g BBs, and the rifle chronoed at around 390-395 FPS, which is perfect for outdoor skirmishes. The range is good — about 45–50 meters effective range with adjusted hop-up. Accuracy is consistent, and the hop-up unit held its setting throughout the day.

The trigger response is decent with the 7.4V LiPo, and the rate of fire is acceptable for most playstyles. The included hi-cap magazine fed reliably, though it had a little wobble in the magwell — nothing major, easily fixed with some tape or replaced with a mid-cap for better fit.

There are a few small downsides to note:

The battery space is limited, so you'll need slim stick-type batteries.

The fire selector is a bit stiff at first but loosens up with use.

It lacks modern features like rails or mounting options, but that's expected for a classic AK design.

Overall, the CM.040 is an excellent choice for players who want a traditional AK replica that performs reliably and looks great. It’s also a good platform for upgrades later on. Just remember that due to its realistic appearance and full size (around 94 cm), it should be stored and transported with care.
After using the CM.040 for a few games now, I feel more confident recommending it not just as a beginner-friendly replica, but also as a solid choice for intermediate players who appreciate realism and consistency.

One thing that stood out to me is the weight and balance. This gun feels solid, but it’s not overly heavy. The front end has a bit of heft, typical for AKs, but with a sling or proper stance, it becomes very manageable — even for longer matches. The folding stock is also very practical for transport or for playing in tighter areas like CQB zones, though the full-length barrel still makes it more suitable for outdoor use.

The iron sights are well aligned and usable out of the box — I didn’t need to make adjustments. I haven’t added optics yet, since the side rail mount wasn’t included, but I plan to install one later. If you’re going for a modern AK look, that’s something to consider.

I also want to mention durability. The replica handled minor bumps, kneeling drops, and sling stress without any signs of creaking or weakness. The paint finish didn’t scratch easily, and even after crawling and moving through rougher terrain, it still looks clean. That gives me confidence it will last through many more events.

One of the smaller touches I appreciated is how intuitive the disassembly is — field-stripping it for maintenance or cleaning is quite straightforward. The dust cover, bolt cover, and hop-up chamber are all easily accessible without tools.

I still recommend replacing the mag eventually, and maybe getting a battery extension mod if you want more space, but for its price, this replica overdelivers in multiple areas — feel, realism, and in-game performance.

This AK Receiver Cover Rail from CYMA is a solid, full-metal upgrade. The build quality is excellent, and it fits perfectly on CYMA AK models like the AK47, AK105, and even the AK47 Beta, which I personally use. After a year of use, I’ve had zero issues, no wobble, no wear. The Picatinny rail is secure and ideal for mounting red dots or other aiming devices. Highly recommended for anyone looking to add optics to their CYMA AK without compromising stability.

just got it out of the box and in place under 5 minuts. work great no wobles and close on the replica perfectly. Ak replica cyma.

Testes with red dot, scope and thermal and everything adpat to it with no problem. Paint didnt chip and looks exactly the same of the replica.

Fits perfectly onto my Cyma AK-74, it’s a little stiffer getting it over the release catch compared to the old cover but once it’s on it’s solid with no movement, it looks really good and tactical compared to just having a side mount rail

Excellent product. Had it installed in about a minute. Stays very securely on the reciever, no wobble. Makes battery change quicker. Only downside is the very wide aperture on the iron sights, working on a solution to make it narrower. I use it with a red dot on a riser which affords aiming down the iron sights.

The Cyma AK receiver cover rail is a practical accessory for mounting optics on AK-style airsoft replicas. It fits well and is fairly stable, though receiver cover rails can sometimes shift slightly, which might affect accuracy. If stability is critical, side-mounted rails could be a better option. Overall, it’s a solid, budget-friendly choice for beginners and intermediate players.

Its a nice piece but it didnt fit.

Thats more my fault becouse i ussed al kind of different brands all thogether.

Still gona keep it in case im gona make a fully cyma build

Realy like the quality

This is a solid red-dot made out of aluminium and clear glass. It's got enought brightness to be seen during the day. You can zero it in, and it'll hold zero just fine. Perfect for two eye shooting and staying true to your Russian bias larp. The sight comes mounted on a high mount so you can still use the AK iron-sights. But you can also remove the stilts inbetween for a low mount. It might be a little hard to aim the MOA2 size dot, but you'll learn to aim with it.


(If the red-dot blinks before turning off, your battery is dead.)

The CYMA AK Receiver Cover Rail fit perfectly on my AK without any adjustments needed! It’s solid and stable, giving my optics a secure mount even during intense games. The durability is impressive, and it holds heavier scopes without any wobble. This rail is definitely a great addition for anyone looking to enhance their setup with top-mounted accessories!

Another exelent replica from Cyma. This AK-74S is very well made. Steel parts are: flash hider, gas tube, reciever, top cover, rear sight, safety lever and the stock. The rest is some other metal. The top cover is fitted very tightly. The flash hider moves a bit, and the cleaning rod as well. And the stock also has some movement. It has a quick-change gearbox (for the spring), but you need to remove the gearbox from the rifle to replace the spring - but it's still a nice feature. The only negative is the magazine: the high cap is totaly plastic - the locking lips as well. So, be carefull with the mag.

This optic is solid and very durable. It has several additional parts just like honey comb kill flash and protective caps with different styles.
The brightness of the red dot is visible even during daylight and it is easy to adjust it's brightness with the buttons.
It has a weight but you receive an aluminium mad red dot which in this case is a guarantee of quality. 10/10

Wonderful replica! Good quality. Feels really sturdy and solid, adequately built and it was good to go right from the box. Don't need no attachment, no nothing. Only a simple AK-style sling to carry it around.

Great quality! Will fit Cyma AKs i guess but didnt fit my cyma RPK without moding. Really love the material and it feels really nice. Will fit on Specna Aks aswell but same there. You need to file it down a little to get that Perfect fit,

Bought 2 of this in pair. One working just fine other one had some problems with plus and minus buttons. But support from taiwangun was good and they responded in time. Other one works fine and holds zero after 2 games of active playstyle. Worth it in my opinion quality is very good and using aaa batteries which are very common.

On a specna edge i had to do a little sanding but other than that, it fits perfectly. The screw that comes with it fits very tight in its own holes, but if you push it a little harder i will go in. I tottaly recommend it.

Perfect piece of equipment, fits like a glove on my CM.040c, I'm using it with heavy scopes and it doesn't move or rattle. Definite buy if you want a scope or sight for your AK replica.

PS. You can also remove the rail if you want, so it can also work as an old school dust cover if you want.

It is properly for me. It was fiting for a Specna Arms AK-105 replica.The material of this product is good quality and the installation is easy. I can recommend it.

Meg vagyok vele elégedve, tökéletesen rámegy egy Specna Arms AK 105 replikára is, mivel mágnesezhető így vagy vas vagy acél, mind a kettő kielégítő anyaghasználatról árulkodik.

Ak74 acessório top cover em alumínio/metal da CYMA que encaixa perfeitamente na minha ak74 da DOUBLE BELL. Material leve e de boa qualidade de construção que permite colocação de acessórios e miras, tornando a arma mais moderna e tática. Bom upgrade para quem gosta de personalizar as réplicas e acrescentar acessórios sem utilizar o carril lateral.

Nicely made, sturdy replica, much better than the cheap Chinese T1 copies, it comes with a raiser, killflash, clear lens protector and standard lens protector. The only downside is the missing instructions, it is not obvious which button does what. It seems it can be switched off by pressing the + and - buttons together.

While it dose fit and looks and preforms grate i needed to sand off a big part of it and bent some parts to get them int place also the screw/pin thing was too big so i needed to get a new one

It is satisfactory now but the installing procedure was a pain

Sturdy build and overall good quality but I don't like how attaching the honeycomb is permanent. Wish there was a way to remove it without damaging the ring. I also don't like that it relies on the 60 minute turn off instead of also having a normal off button.

Great item and upgrade!
I bought it for my CYMA 040C, to make an upgrade for the better estetics and to able to mount a red dot in near future.
Very good quality build material, nice paint matching cyma reciever paint.
Instalation is straitforward, keep in mind that you have to say goodbay to the rear sight view.

Very sturdy rifle, with little to no wobbling. Feels great in the hand, not ideal for cqb but performed pretty great for me even in that regard. It pleased me on my games so far and I have not spared it. Would recommend to sight/range it before first game and a lipo 7.4 (be sure to get a stick, the brick shaped ones don't fit).
Would recommend it as a first AK

Wonderful compact red dot!
The dot is sharp, no problem with outdoor playing.
Almost too many settings.
The QD mount did not fit my lct rail. So had to modify the rail a bit.
Works great on my AKMSU now after the rail is modified.
Comes with many accessories.
Would buy again!

The product is solid and well done. Stable slide and no backlash. But be careful, with the Specna Arms replicas, in my case SA-J10, the cover is not compatible, unless you scratch off the material at the point of attachment to the replica. If this change is made, the component becomes perfect and closes perfectly.

Kinda hard to get the pin in that holds it together in but once you do it's great. Also a lot sturdier feeling than the stock CYMA dust cover, but it is heavier so if you are really really worried about weight you might not like this.

Fits like a glove! Bought it for my Cyma cm.040 and the fitting is incredible and installing the dustcover is easy with a little help of a video on Youtube. Makes it alot easier to fit an optic or red dot. Well made and money well spend.

The Cyma cm.040 was my first replica. I was looking for something reliable and sturdy, which i could upgrade in the future.
I’m very pleased with my purchase! Cyma has a reputation for building incredible sturdy AK replica’s for a budget price, they exceeded my expectations!
Thank you Taiwangun!

preso per un ak cyma 105 si adatta perfettamente, montaggio in pochi secondi senza chiavi o necessitá di modifica della replica
solido e ben refinito senza sbavature
anche l'aggancio è preciso
la slitta superiore permette il montaggio di dot anche senza rialzo

I have mounted on my E&L ak replica but l had to file about 0.5mm from the mounting hinge.
The screw provided is not good, doesn't enter in the hole, so u must find a replacement.
Is good for the tactical look, has a lot of play on the back of the rail. Your optics will hold zero if mounted forward where it connects to the back sight of your Ak.

Need a bit of modifications, but way better compaired to the original....
Im using this for my cm028s, with Red dot. The original was a bit strugle to put on, with this, ots totally different situation.....

Very nice great-looking AEG. I only replace sight to same detail from real AK-74 and add Soviet shoulder belt. Also recommended used magazines in real bakelite bodies and thin handle with motor.
Price was very nice, delivery take only 3 days. And thanks to Taiwangun to safe packaging and small gift (500 ball bullets).

Fits an E&L AK-105 replica with some grinding. If you're handy with a grinder or dremel tool I think this will fit many AK replica's.

All grinding had to be done in order for the dust-cover to fit the rear sight block. 290mm fits great on my E&L, but also one of my Cyma AK-10X replica's. Its measured from the center of the pivot in from to the back where the dust cover fits the recoil spring.

Not knowing what models it would fit made me a bit hesitant to buy it, but i'm used the fabricating metal parts, so for me voiding the warranty was no big deal.

Buy it at your own discretion.

“It’s f-ing antiaircraft cannon, Vincent!”

Besides lines, it’s an awesome replica.
Heavy, but very solid.
Thanks a lot to Taiwangun Service for their availability to downgrade the replica to 310 fps on request just before sending it to deliver courier. Cyma mags (both midcaps and hicaps) perfectly fits with it. Smooth cocking handle. I just changed the nozzle with a 5KU DShK-like one for aesthetics purposes previously ordered on TWG, and it really looks like an anti-aircraft cannon. I’ve been advised specifically with CM.04x-series since they have VFC-based mechanics instead of TM-based such as .03x series is. Pretty solid, and fits both stick batteries and shorter squared-section batteries too. Bought on black friday. Interesting replica, with a lot of compatibility between most AKs (except AKSU but that’s a completely different body).

A MUST upgrade for ak users. This kind of rail gives you many possibilities like scopes, flashlight, lasers and many more at the top of your airsoft gun. Unfortunately the installation was a little bit hard for my CM.520, so you should check your replica and compatibility.

Looks good, solid piece of metal. Took a bit of filing work to fit it on a DoubleBell AK replica but the result was satisfying. (Also nice to be able to just hinge open the top cover like on a belt fed lmg.)

First of all, beautiful gun! I bought it reshimmed etc at 360 fps. Shoots very accurate! Hop up is easy to adjust. Gun feels sturdy and strong! Great gun for everyone! Beginner or someone who wants to upgrade it!

It is a solid rail and great if you are looking to add a picatinny rail to your replica. However it did not fit my cyma AK, so i think ot would be great if taiwangun adds models that fit this item in the description.

Cyma AK'S are great for Veterans or beginners. Gun is all metal body with amazing details, you can not tell this is not the real thing. Gun shoot great out if the box but with minor upgrades the thing is super accurate and has great range. Check your local field for fps limit and bb regulations before your first game day. I use the recommend .30g BBS. Great gun for my first air soft rifle!

This gun is just amazing. The build is solid, but the weapon itself feels compact and not too heavy. The steel parts feel really nice on this one, I still need to get used to the polymer parts but those are also sturdy. The accuracy suprised me, the bullet spread is minimal, the gun shoots straight without any upgrades out of the box. Excellent replica for beginners and advanced airsoft players too, especially for this price, I definitely recommend for anyone.

Construction is fenomenal with mostly metal and only some plastic ( handguard,pistol grip and such). Very nice to hold and it feels very
hefty and sturdy. Internals are very easily accessible

My only two gripes with it are :
- Most magazines wobble a lot , this did not have any effect on it feeding the BBs but takes a little bit out of the immersion factor.

- The folding stock is VERY stiff, it needs at least 20-30 open-close cycles for it to loosen up a little and be foldable with a normal amount of force.

All in all I am very happy with this replica and would recommend anyone give it a try.

I experienced a slight inconvenience the first time because the front grip has a bolt, but everything else is great, the material is stable, the coating is quite good and does not wear out from bumps and scratches, and the rail is large and high and no additional lift

I really did not expect a better weapon for this money and feel so stable, also the battery that is a gift is quite nice because it saves extra costs and I am quite grateful for the fast delivery and correct attitude of taiwangun

Advantages:
-very low price(for such great build)
-strong material(feels like a metal)

Disadvantages:
-it doesn't fit on cm.031 (I miss this information in description)

I give 4 stars only because it doesn't fit for my gun and it is needs to small changes to be done (which is not so simple when the material is metal).

If you're looking for mid-price airsoft this one is definitely it. 95% of the gun is metal so it feels like the real thing, and shoots accurately too. Honestly, I don't have any minuses to share about this AK. I definitely recommend this product.

I take this item for the second time. Good, strong material. Good workmanship. Excellent combination of price and quality. Compatible with Суma's replica. I like the way it looks on the replica. Painted well. All the parts that I had came up on the picatinny bar. Easily installed. Makes it easier to change the battery while playing. Sits tight, does not dangle.

Excellent workmanship, as it is a blue edition, it also has good properties in terms of shooting (I recommend 0.28g-0.30g), there is nothing missing, but I recommend replacing the cable with a better one if you want to use 11.1v. For me, complete satisfaction and I recommend 100%.

Good rail, good metal.
Works like you want it to

It does not fit cm028 right away but If you file a bit from the front sight block you can make it work, It looks nice on my cm028

Filing required to fit cm028
