CM.103 AK assault rifle replica [CYMA]

After using the CYMA CM.103 AK regularly for around two months, I can say this replica left a strong impression—both positive and negative—but overall it proved to be a serious platform, especially for DMR and milsim use.

The first thing that stands out is the weight. At roughly 4.5 kg, this is one of the heaviest AEGs I have used. After about two hours of gameplay, arm fatigue becomes very noticeable. This is coming from someone who regularly uses fully metal M4s and a modern AUG A3, both heavily upgraded. The CM.103 clearly demands physical endurance, and for that reason alone it is not ideal for fast CQB play.

Build quality is otherwise excellent. The replica features a full metal and polymer construction that feels extremely solid and realistic. Most parts feel durable and well‑fitted, and the adjustable stock is easy to extend and collapse. Once you get used to it, the trigger feels good and predictable, and the grip is comfortable. I added a HERA Arms foregrip, which not only improved handling but also gave the rifle a unique, almost sci‑fi appearance that I really enjoy.

Disassembly is one of this rifle’s strongest points. The design is very user‑friendly: two screws hold the entire rifle together, allowing full disassembly in about 20 seconds. The quick spring change system works flawlessly, and even swapping the inner barrel is fast and simple. This makes maintenance and upgrades extremely convenient.

Speaking of upgrades, I converted this rifle into a 2.9 joule DMR setup with an M150 spring, new inner barrel, hop‑up unit, and bucking. In this configuration, the CM.103 performs exceptionally well. Accuracy, consistency, and range are excellent, and it truly feels like a DMR beast on the field. I ran it with seven mid‑cap magazines, all feeding reliably.

However, there are several notable downsides that potential buyers should be aware of. Battery compatibility is very limited: the rifle requires a long stick‑type battery, and fitting it into the gun is difficult. Battery choice is restricted, and availability is poor. This is one of the most frustrating aspects of ownership.

Another weak point is the side rail mounting system. The screws used are of poor quality; when attaching a sling, the screws loosened and fell out almost immediately. This is disappointing on an otherwise solid replica. Additionally, the flash hider cannot be unscrewed, which means mounting a tracer unit or suppressor is not possible without modification—a significant drawback for many players.

Because of the weight and role, I ended up using the CM.103 actively for about two months, after which I transitioned to lighter CQB setups (AUG A3 and short M4 platforms). The CM.103 has since remained in my collection as a dedicated DMR rifle for milsim events, where its power shines.

CYMA CM.103 AK is a powerful, realistic, and well‑designed platform with excellent internals and upgrade potential. It is not a casual or lightweight rifle, and it has some design flaws—particularly regarding screws, battery space, and muzzle compatibility. That said, if you are looking for a heavy, robust AK‑style replica suited for DMR or milsim roles and are prepared for its weight, this rifle delivers strong performance and it just looks damn cool.

One downside is that installing the battery requires completely disassembling the gun, which makes the process a bit tedious. However, aside from that, the weapon performs excellently in all other aspects.

Fantastic replica. Really solid construction with a unique design. Great for left handers. Performance is on par or better with anything else that I have used. Taiwangun delivery was also excellent. Thanks and great job guys.

Awesome Gun. Shoots really well. Can handle bad weather, i just played in the rain and it did not disapoint. Only bad thing is the battery, you are limited on space so you have to buy a very thin battery. Other than that, enjoy

I purchased this replica both because it was unusual and because I wanted to get a feel for CYMA platinum line.

Build: I'm just impressed. It's a lot of polymer on the outside, but it's high-quality and the tolerances are very tight. The thing is a joy, and while I'd love to see more padding on the butt stock, and I'll likely upgrade the pistol grip, I can find no fault at this price.

As a gun: it's pretty forward heavy. It's more fatiguing than me SMGs or M4s to carry and fire. I suspect this is common in AK-derivatives (while this has M4 controls, the barrel system is clearly AK inspired.

As an airsoft: I haven't done a lot of shooting with it yet, but I did spend some time dialing in one of my red-dots. It shoots straight and consistently. I've had no feed failures and can reliably hit targets at the ranges I've been shooting (about 20-25m).

I haven't clocked this, but tuned this would make a lovely DMR (I recommend a vertical foregrip as it makes the weight more tolerable). For skirmishing it's a bit long/heavy, but YMMV.

I bought this AK half a year ago, at first I was very happy with the purchase, because this model looks very cool!
But there are a few nuances! They wrote here that there is very little space for the battery. This is true. BUT I was ready for this! The machine gun worked perfectly in automatic mode. The rate of fire is excellent and the range too. BUT in single fire mode - it is a disaster! It seems that this is a product of past years! Very slow trigger response! And it doesn't matter with what battery! This cannot be cured by anything! I am very upset!
It is a pity that in 2024 there are still such problems!

Used this twice and it started shooting full auto on single fire. Took it to the local shop for repairs and was told the dedicated gear box went out and is not fixable. Waste of money. Not sure what to do now with a decorative piece. I wouldn't recommend buying this item to anybody.

This rifle is not meant to be carried by short people, it is very long. In my opinion on of the recommended battery doesn't fit under the dustcover. This one - https://www.taiwangun.com/lipo-11-1v/battery-li-po-1450mah-11-1v-20c-t-connect-ipower-2
The rifle itself is very comfortable, reliable and very well built. Using 11.1v battery the rate of fire is amazing.

1. Appearance and Material Utilization:
- The appearance of the CM. 103 AK closely resembles the original AK series firearms used by the Russian military, making it easily recognizable on the field.
- Components are predominantly made of metal and plastic. Metal parts are robust and durable, while plastics primarily contribute to comfort.

2. Operation and Performance:
- Based on my experience, the electric-powered CM. 103 AK is highly reliable and efficient. Operating it with a battery is straightforward and convenient.
- The integrated hop-up system enhances projectile flight characteristics, extending the weapon's effective range.
- Compatibility with airsoft valves facilitates easy maintenance and customization to individual preferences.

3. Comfort and Ergonomics:
- Thanks to its ergonomic design, the CM. 103 AK fits comfortably in the hand, providing a stable grip for improved accuracy and rapid response.
- Its lightweight nature allows for easy handling over extended periods, a significant advantage during prolonged airsoft engagements.

4. Accuracy and Targeting:
- The precise sighting system and easy trigger control enable precise targeting and swift reaction times on the field, which are highly advantageous in airsoft scenarios.

5. Durability and Quality:
- While some users may report manufacturing defects and lower-quality materials, my experience suggests that the CM. 103 AK is extremely durable and reliable.
- It offers excellent value for money, providing satisfactory quality relative to its price point.

Overall, the CM. 103 AK is an excellent choice for airsoft gameplay, combining reliability, efficiency, and affordability.

CM. 103 AK assault rifle, I feel like I'm dealing with a reliable and efficient airsoft weapon. I would highlight its easy handling and comfortable grip, which allows for extended gameplay without causing fatigue. Additionally, I'm very pleased with its precise sighting system and easy trigger control, which helps me deliver more accurate shots. While I've heard some concerns about manufacturing defects and lower-quality materials, personally, I haven't experienced any issues with my rifle.

-nagyon jó a fogása
-jobb és balkezes kialakítás
-jobb tár kioldás
-jó tűzgyorsaság
- cyma47\74, battleaxe 47 tárakkal kompatibilis
eddig nagyon jó fogású és nagyon kompakt replika, egyszerre hordoza az AK és M4 jó tulajdonságokat.

I took it out on several games now and so far these are my findings:
Good:
-Superb build quality. No wobble, no rattle and also the stock is rock solid. Its a dream after an M4 platform stock! :)
-Great weight distribution. The gun is very balanced, slightly heavier in the back. I have pretty bad shoulders, and its easier to hold out this gun compared to my previous Specna H20.
-Great ROF out of box.
-Really easy to disassembly it. Two push pin holds it together like the real steel.
-Midcap with 200 bb capaticy.
-Spring quick change is indeed quick, not like on some other platforms.
-Rock solid internals, except the nozzle.
-Uses standard AK hopup and nozzle lenght.

Bad:
-Good ROF, but in semi it likes to overspin a bit with 11.1 so I would recommend lower voltage battery.
-Reaaallly smal battery compartment. I mean it. Max battery size which fit is around 20mmx20mm, so keep that in mind. The uniqly designed gearbox doesn't help with this. Due to its open nature, it needed a sheet metal piece so the battery charging connector don't get in the way of the spring in the gearbox.
-If you want to upgrade the ETU unit in the gun, you need a unit with optical sensors, due to the hybrid unique V3 gearbox and the M4 Fire mode selector. Perun Hybrid wont work with this gun, but a Jefftron Leviathan will.
-When I changed Hopup rubber, I noticed pretty huge burrs inside the nozzle. Definietly comes from bad manufacturing, also it has no o-ring so upgrading this part can be improve airseal a lot.
-Also this replica has no barrel thread so to use a silencer or tracer, you have to modify the outer barrel, but its doable.
-Mine came with lower FPS than stated, Around 340 FPS out of box.
-It has a 12 teeth sector gear, which means it heavily shortstroked from factory. It might the a reason for the low FPS. Its not really a bad thing, but in this case not a good one either.

Overall i'm really satisfied with my one. Its an unique looking gun, I never ran into another one on the fields. Has its own little issues as you could read it above, but nothing major. As someone who hates the AK furniture, but otherwise like the AK looks this is a must get gun. Would recommend to anyone! :)

Отличный автомат . Работает как часы . Я очень рад что купил такой экземпляр . На автоматическом огне работает как пулемёт. Лёгкий комбинированный пластик и сплав алюминия . Выглядит супер . Работает отлично имеет рейлы для ручки прицела и.т.д

I know many people don't like the look of it, but that's one awesome replica, feels great in hands, shoots even better, responsive trigger and high rof, the only negative side so far is the battery compartment, probably the first replica i've got and didn't get the feeling I should change bucking and nub at least(my 5th Cyma Platinum), very impressed

I bought this rifle last month. The rifle itself is great. The only con is the battery-compartment. Like other reviewers say: it is very small and the battery that I bought times two -(BATTERY LI-PO 1450MAH 11,1V 20C - T-CONNECT [IPOWER] - which is recommented on this page - does absolutely not fit in the compartment. I tried to get in contact with support but they won't come up with a suitable solution. Only that I "have to adjust the wires and it is ok". Be carefull which battery you order for this rifle!

This gun will perform exactly as you want it. Everything on it is sharp and snappy, with a pretty satisfying bolt as well. Sits very comfortably in your shoulder and trigger hand, as well as easily being swapped to the other hand because of the ambidextrous layout. The two adjustment options on the stock make it a "one size fits all" package.

Only thing is that the mags will wiggle just a bit side to side when in the magwell, but I've found that true with most ak style magwells.

Overall it is a great gun. The material is solid and the gearbox works smoothly. I got mine in a fairly low FPS configuration, but have not run into any problems during usage.

The only thing that prevents me from leaving a full 5 stars is the battery compartment. This gun has a super tiny battery compartment, and if you're like me and a US resident, the batteries recommended here can't be shipped to you.

My advice is one, make sure the battery you get is slim, at most 18mms wide. Two is a bit of a personal trick, but essentially the compartment can be slightly widened with some elbow grease and some creativity, but be VERY CAREFUL! Try to get a battery that fits first before doing any major modifications. I'd recommend taking the product code from one of the provided battery examples here and searching for it that way.

Otherwise, a fantastic AK platform. My old CYMA and KWA mags fit and feed with no issues. I use an 11.1v battery and have had a blast with it. Great modern-style AK without those ugly crane stocks bolted to some railed-up AK74.

I tested this AEG 2 games so far and feels good overall, good trigger response, being ambidextrous is a must and love that stock, i don't use it folded but I appreciate having the option. In addition you can remove the lower picatinny rail and it has an Mlock rail so you have both options as the descriptions says it weights about 3kg and if you are not used to it can be bothersome but the weight on the replica it's balanced so i didn't notice much that weight. Overall it feels good, the only issue i found is the battery, ak's, but they added a piece between the stock that when you fold it you can remove that piece and reach the battery, can a bit tricky to do so but it's doable.

In conclusion, if you don't mind the weight and the battery placement, go for it , it's a damn good replica for it's price.

I bought two replicas of this kind...very satisfied with one that came perfect, shoots well...but the second replica came with a defect, it could not be fired at all with the trigger blocked...in the end it was avoided to send it from Romania I chose to repair it at my own expense... I subtract two stars because you did not test the replicas before sending them... as it says on the website...
