CYMA Platinum M4 QBS Airsoft AEG Rifle (Model: 8.5" M-LOK w/ Shorty Stock / Gun Only)

"This is my re-review of the CYMA Platinum QBS M4 13" M-lok rail model

I have had this replica for about a year now, and I have some things to say about after my previous review. My previous review was my experience with the replica with almost stock internals. The only thing I changed at the time was the Pro Win hopup I installed into it as the stock CYMA hopup leaves much to be desired. At one point, the stock mosfet broke, and no it didn't fry itself, I broke the microswitch by accident medaling with the internals. After this, I mainly forgot about it and left it in my gun case for some time. Recently I've purchased new internal upgrades for it. Those upgrades are:
Perun V2 Hybrid mosfet
ZCI 6.02mm 363mm Inner Barrel
PDI W Hold 50 degree Hop up bucking

After installation of the Perun Hybrid mosfet, which requires only a tiny bit of gearbox modification to install, dremel tool recommended, the replica sings. The range was also improved by the W Hold bucking and the ZCI inner barrel, although I believe the range can be greater with heavier weight BBs as I only have .25g BBs. After these upgrades I will be using an 11.1v Lipo to run my gun which is the optimal battery to use after these upgrades, however with the stock mosfet I recommend a 7.4v Lipo. The replica might not run as fast as with an 11.1v Lipo, but with the stock internals the 7.4v will run this gun pretty well, the RoF will be slower but you will still have a snappy trigger response.

I would recommend this gun to players who have an understanding of how airsoft AEGs function, but I cannot recommend this gun to new players as there can be complications with the stock internals further down the line. The must have upgrades to get for anyone buying this replica however is a new hop up and bucking, the stock inner barrel is brass and is of pretty decent quality.

In terms of rating, I would give this replica a 4/5 stars in terms of stock performance, but after the upgrades I installed I would give this replica a 5/5. It's a really good replica under 300$ that can be easily upgraded with a basic understanding of internals and enough patience.

"Absolutely solid gun rof is great and range is pretty good i have dropped in a modify flat hop and prometheus barrel in it as well and it handles 11.1 lipos like a champ

"I absolutely love this gun. I have put it through some rough games and it has taken it like a champ. It is very accurate for being right out of the box. The only thing i would honestly upgrade on this gun is a better trigger response (even though the stock response is great) I want it a little faster for the indoor airsoft I play. I got the 10” for indoor and it is the best investment i have made.

"I have yet to go to a field and try this bad boy out, but when I took it out of the box and fired it with a half charged 7.4 LiPo battery, it shot amazing. I had no problems with the gun when I was unboxing it, and everything was in the package that it said included. I would recommend getting a dot sight because it doesn't come with a sight, and the sight that the gun naturally has is not that good. (p.s. you can take the natural sight off with a penny or flathead screwdriver). Some of the things that I have put on mine so far are: a reflex sight, keymod grip, and an 11.1 LiPo battery so that I can get to that 24-28 rps with the boys.

PROS:
Shoots great with great accuracy
Sounds awesome
Has nice weight to it so that if feels real enough
The gun is very hefty and built with the right metals

CONS:
Haven't had any at all

"Hands down the best gun stock gun on the market! The looks are beautiful to start, and it’s surprisingly light for being all metal. The hopup is a dial type (on mine anyway), but it is wired to deans. The stock is quite comfy and offers a pretty good amount of space. The QBS system is amazing. The spring guide is all metal and features a ball bearing. One thing to note: the stock spring guide fits in the back of a Retro Arms QC gearbox shell, which may suggest that the QBS system can still be used even with certain aftermarket gearbox shells. But, of course, the performance. The trigger response with a 7.4v 16c 3000mAh Titan Li-Ion battery is instantaneous. And the rate of fire is pretty quick, too, at around 15rps (which is quite impressive for a stock gun). All in all, this gun is fantastic and I can’t wait to field it! Not to mention the price. This gun can easily cost more than it is, but, no, it’s less than $300. Seriously, you’d be a fool to pass thing thing up.

"Total game changer out of the box. This is my second Cyma. First one is AK74U ( Total tank).
Pros :
Accuracy: 10/10
Ergonomics : 10/10
Lightweights : 10/10
Ease of battery change 10/10
Ease of spring change 11/10 (not kidding)
Shot to shot consistency :10/10
Performs the best with 0.32s
This gun loves both 7.4 and 11.1 LiPo
RPS is 28 with 11.1
FPS with stock spring with 0.30s is 285FPS
Quality of built is solid 10/10

Cons:
Do not exist.

"Let me just start by saying you WILL NOT regret buying this AEG. The ROF is unreal with an 11.1. I personally run a 7.4 majority of the time but I’ll just throw an 11.1 in to flex on people lol the FPS is good ~370 out of the box. I’ve put about 10,000 rounds through mine so far and myself and everyone I’ve played with are beyond I mpressed with the Cyma Platinum series. I recommend for a new or experienced player because you just can’t go wrong with it. All aluminum body, comes with a tight bore inner barrel, quick spring change system and a trigger MOSFET right out of the box. 10/10 in my book.

"I bought this gun about 7 months ago, and I love it.
Very reliable, and very cool looking as it's a CYMA.
However, it does need some bits and pieces to be good.
Such as a rotary hop chamber
DEANS plugs
Maple Leaf MR-hop
Maple Leaf Omega nub
Maybe a new barrel (ZCI, Angel Custom, not a Prometheus)
And of course, .28-.40 gram BBs.

After those parts, your gun will be better than any Krytac, SSR15, G&G, or any other gun for that matter unless of course they have the same parts, and be quite affordable on top of that.
The quick change spring is also very nice, as it's actually quick change and all you need is a coin, or flat head screwdriver, or Allen key to change the spring.
If you complete the upgrades as listed any, you may want a weaker spring as you will probably be at 450 FPS, but other than those things, your gun should be close to perfect.

One word of caution when getting batteries for this gun, only get a 7.4 volt LI-PO or a 9.6 volt NI-CAD, 11.1 will cut the lifespan roughly in half as it puts too much stress on the entire gearset and motor.

I would recommend this gun 10,000%, best AEG I've ever had and insanely reliable compared to all of the ones my friends and I own.
Totally worth the money, and it's not even too expensive to begin with.

"Just got mine love it so far, only thing is that it says small Tamiya but mine came with a deans I guess that’s better but all my batteries are Tamiya so I’ll need and adapter, other than that great gun!

"I won this in the Swagg pack and I have never been happier with a gun. It has an amazing hop up and can easily get a lot of range from this gun. It’s not to heavy but it’s durable as heck.
Pros:
Everything

Cons:
Nothing

"The best AEG I own right now, and probably the best one I'll ever own. Looks, feels, and sounds amazing! Highly recommend this gun to any intermediate or even veteran airsoft players. Range is great outta the box and the trigger response is crisp and clean. ROF on a 11.1v is high (nearly 30 RPS), will be getting a Titan 7.4v soon and I'm hoping the trigger response is as good on it as the 11.1v. 5/5 stars, got it on sale but I would spend the full 275 dollars on the 13" version.

"Just got it today but I was really satisfied with the quality and the performance of this m4. I love everything about it right now but hopefully it will hold up for years before it stops working. I’ll probably update this within a month or two

"Have to say this rifle for regular price is a steal and if you catch it on sale it’s a mistake not to buy one. Trigger response is just awesome. Loaded with 7.4 lipo it spits bbs almost as fast as you can spam the trigger. The hardest thing I’ve had to deal with so far is finding mags that feed as well as the stock mag. There’s plenty of battery space in the stock for stick style batteries that I use. I had difficulty removing the flash hider due to a stripped lock screw but after removal it was easy installing a new mock silencer. This thing also took a major liking to the 11.1 lipo I tried. There seemed to be a slight feeding issue that could easily be solved, ot a technical person so not sure what needs to be done but this thing still spits bbs like crazy.

"This gun is outstanding out of the box, it gives the trident mkII a run for its money as best aeg out of the box

"November 2024
Great performance out of the box with an 11.1 Lipo and .28g bbs (outdoor field). Hopup is a bit stiff but still functional. The only complaint I have is that the mag that comes with it wiggles a bit too much and the dust cover latch arrived broken but that does interfere with the operation.
