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

"Great gun so far! only problem is that one of the sling mount points keep falling off by unscrewing

"I can confirm, these now come with a WAY BETTER mosfet and a ROTARY HOP UP! As of June 2024.

Absolutely amazing. Extremely snappy trigger (I use 7.4v 2500mah deans lipo Matrix batteries), very high quality feel, very durable QD points, full metal body, and almost perfect shimming out the box. I was very torn over time deciding which new gun to pickup and this by far blew my expectations away.

Caution, that MLOK is sharp. USE GLOVES.

I can confirm the new batch of these are muchhhhhh better now.

"Yes, it's better than a Krytac, VFC, G&G, Arcturus, at this price range.

Yes, put a Perun hybrid in it.

Yes, you can run an 11.1v Lipo once you've done that.

No, it's not hard to install.

"I've had this gun for over 4 years and have rebuilt it many times. I run an 11.4 with a 30k motor and the stock internals had no problem. I would recommend this gun to anyone

"I wish I could leave a 4.8 star review, but 5 represents this gun fine.

This gun is very worth it for the price, especially on sale. After adding a GATE Titan, MAXX hop up, and other compression parts, this thing is a beast.

Pros:
Great construction - handguard and receiver are made from metal and the stock and grip are high-quality polymer
Good FPS out of the box
Able to hop .28s with no problem
DEANS!!
Snappy trigger
Super easy to take apart if you have to reach the gearbox
Stock compression parts are above average with a metal tooth piston double o-ring head. The gears are good too

Cons:
While I didn't run 11.1v LiPos for this reason, it is a common issue for the mosfet to melt on these (fixed with any third-party mosfet)
The handguard becomes wobbly occasionally and you have to tighten it with a hex key
My motor height screw would sometimes shake loose from firing and require me to re-tighten it
(These cons are minor issues)

In all, I highly recommend this gun with just a few issues keeping it from being perfect. With some simple upgrades, all of these issues can be solved and will leave you with a nasty BB-slinging gun.

"This gun is amazing so far. The fire rate is very fast and has a great response time. When pulling the bolt back if you don't let go and push it in manually the bolt release will not work. Comes with a pretty good mid-cap you can also use high-caps. The mags do shake a little when in the mag well but nothing concerning. The iron sights aren't the best I would recommend a red dot or something like that. The gun feels great to hold and fire. The M-LOK rails are the perfect size there not to big or small(I've had that problem before with other guns). I would definitely recommend the 14 M-LOK one the 13 is a little to little for my liking but if you like a smaller gun its for you. I would recommend this gun to anyone I love it

"Awesome gun. Trigger response and ROF out of the box are well above average. Bought a Perun hybrid v2 mosfet to upgrade this soon.

Got the 8.5in mlok version.

Gun is very well built and quality is good. The suppressor is a real pain to take off, I had to drill out a pin holding it in place and then melt some glue. Accuracy is good but could be better. Shoots 295-300fps with .32's.

Overall I would highly recommend this gun.

"Bought this gun a few months back, so far it has been a great gun save for one minor setback. I got the 13" model.

Couple things to note, you can't tell from the pic but under the orange ring is a 3 prong flash hider, and the orange ring breaks easily....allegedly.

Also, this thing is an absolute beast with an 11.1. The midcap it comes with won't last very long, but even at 40+ rps it has no issue keeping up. Impressive for an OEM midcap, if you plan on picking one of these up and need mags buy the CYMA ones with it. I normally run KWA polymer mid caps, they do fine but they always need a good smacking to get them to seat in the mag well.

The gun isn't the most accurate out of the box, but it isn't horrible. Definitely switch to an r-hop, it will make a giant difference.

I ran the gun a few games totally stock before I swapped in my asg high torque motor, the stock one is actually really good. I just knew my asg I had sitting around was better, so I put that in.

Mine shot 395 fps consistently out of the box.

Only issue I have had (with both motors) is it occasionally locks up on semi auto for some reason, I haven't been able to figure out why. The mosfet blinks red in the trigger, I always unplug the battery and plug it back in and it runs as fine after that.

Some people have talked about the mosfet melting, I have not had that happen but will be putting a gate aster in just in case regardless.

Overall, very impressed with this gun. CYMA has come a very long way with their build quality. The finish on this thing feels even better than my real armalite ar15. If you are a beginner looking for a first gun or to upgrade from a budget model, you won't be disappointed in this.

"Great gun without needing any upgrades, maybe the hopup and barrel if you wanted to but not necessary

"I can without any doubt say this gun is tough. Like really strong metal. How I know you ask? Well this gun was laying parallel in the trunk of my 2016 wrx when I was stopped and then rear ended by a young girl who was doing at least 55 to 60 my car was totaled from the back and this gun walked away while a single crack on the receiver and it knocked my orange tip off somehow. Crash happened Jan 1 gun still works with a Lipo months later with 5 to 6 games played since shoots beams still. Voided my warranty cause i bought it at a local store but thats about it.

"Had this gun for around 5 months, I run a Titan Power 7.4 lipo and it works like a charm. Shoots around 22-23 rpm, with .25 bbs it shoots consistently at 350-360. With .28 bbs it shoots consistently at 340 fps. The quality of the gun feels good and the range is incredible, it can shoot accurately for around 200ish feet.

-A Honest Reviewer

"13" model here, yeah this thing rocks. I literally sold my MP5, P90 and Scar because of this. I can't go back to mechanical trigger anymore it's just impossible... You won't regret this especially on sale, though if you have to pay full price, grab the umbrella armory model, same gun with cool engravings. CYMA OUTDID THEMSELVES

"amazing starter gun i loved it

"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
