PTS Centurion Arms CM4 with KWA AEG3 System Airsoft AEG Rifle (Model: Gun Only)

"Amazing AEG!!! Kicks almost like a GBBR.

Pros:
- OH MY GOD THE BUILD QUALITY!!
- 18-rps- ish on 11.1v lipo
- Range is okay out of the box
- Firing it full auto gives you giggles
- PTS Centurion Arms markings and licensing
- Weight is distributed evenly and holding the rifle feels like no other
- Mag cutoff feature is great (though you will need to buy KWA/PTS ERG mags for it to work)
- Plenty of space for nunchuck or any other style of battery in the stock.

Cons:
- For $400 gun they could have included a better motor. It is standard KWA motor and sort of struggles.
- Some airsoft optics and raisers can come loose because of the violent recoil, recommend Loctite.
- Screw on left fire selector comes off a bit after a game or two, you will need to tighten it (needs tiny tiny hex key)
- Definitely eats up batteries faster and boy, once the battery is getting low you will feel it (sluggish response due to ERG system)
- Limited upgradability. Recommended to leave it stock until something breaks. Upgrade to high torque motor is recommended.
- Compression was subpar out of the box, had to upgrade it alongside with the motor.
- Running optic w/raiser, PEQ, foregrip and a suppressor really adds up to the weight. (I need to exercise more)

Notes:
- Mag release is not TM spec (MAXX ambi mag release will not fit)
- Action is loud and gun sounds "unhealthy", though it is supposed to sound like that due to KWA ERG system.
- Increasing ROF is not the best idea, gun shakes a lot as it is, adding more cycles per second will definitely doom internals. Definitely upgrade to highest torque motor you can afford. The stock one needs to be thrown out.

"Really Solid Build

Switch Life Extender (like on the VM4A1)

My First Complaint is that the Recoil system shakes inside the buffer tube. So being sneaky and quiet with it is a little challenging.

My Second Complaint is the selector switch on the Left Side is A LITTLE loose. I checked both of my VM4A1's Selector Switches and they also wiggle too when applying LITTLE pressure but on this gun it's Slightly more loose. But I'll leave it as it is.
it shouldn't break or fall out when using it. Plus i seen people play aggressive with their selector switches in videos. 9/10! HIGHLY Recommend.

"Feels amazing, balanced weight, easy to customize, looking great.

"This thing is the best M4 I have ever owned. I have only owned it since October of last year but it has never failed with the tens of thousands of rounds I have put through it. With .28 bbs it fires around 350 but its range is stellar. Firing this thing on full auto to suppress a position is absolutely amazing. The blowback makes you feel like a boss. I would HIGHLY recommend you use an 11.1 Li-ion in this thing. As it is an electric blowback gun, you'll need that extra juice. Another favorite feature is the buttstock, it is so comfortable and has plenty of batter space for that 11.1 Titan Li-Ion num-chuk type. The rails on this thing are pretty sturdy to, I'd suggest a riser for an optic but that goes for most M4's. Hope this review helped

"awesome gun especially with upgrades, feels solid and robust great for training and simulation. very happy!!

"Beautiful gun, with a few flaws, but nothing major.

I rounded up to a 5, but would most likely leave a 4.5/5

Pros-

-Recoil is very crisp and feels very good. I was surprised by how fun it was to shoot.
-Very consistent fps in the 393's. Just as advertised.
-Quick change spring system in the back, is VERY easy to use. Can swap a spring in 2 minutes. A huge bonus. Lowering the spring will also substantially reduce the recoil feel, which is nice if you arent feeling like having any.
-The front mag well is beveled, making it considerably more comfortable to hold if this is where you place your hands.
-Although it is not advertised, this does come with KWA's switch life extender on the motor. This isn't as good as a MOSFET of course, however, it should help prevent a large amount of damage Lipo batteries do to the trigger contacts and certainly welcome addition.
-Very good fire rate. Impressed that it was able to shoot this fast, considering spring strength, and having to work the recoil system as well.
-The trademarks look better in person.

Cons-

-The motor could provide a bit better torque. The higher-pitched winding noise it makes is a little more than I usually like. This also means that anything under an 11.1 provides sub-average performance unless you change the spring. I believe it is because this motor was designed for speed, rather than torque.
-You need to have an empty Kwa proprietary magazine in order to lock back the bolt to access the hop-up. I understand the propriety magazine should be needed to restrict the gun from firing, but I don't think it should be needed to lock the bolt back to access the hop-up comfortably.


Love the gun, and highly recommend to anyone looking for a recoil aeg. Test of time will speak to its reliability, but initial impressions are great.

"This aeg is truly amazing. Always have an expectation on KWA product but this aeg, KWA made it really nice.
Very realistic feeling, color of the rifle and weight, robust feeling (no wibbling what so ever, but you can feel some movement in the rifle due to the blow back sysem) is really close to the real rifle. Power is really good, shoot around average 385~390 FPS and it reachs 70m and max range is more than 80m if you control your hop up well.

There is one downside which is the hop up system. I mean you cannot get any hop up from this aeg so you need to switch the whole inner barrel, hop up rubber and bucking as well. Which cost me extra 60~70 bucks. But once its fixed you are good to go.
Very accurate and you can shoot all day with this aeg. Just let you know you can't put mosfet nor titan in this aeg...just to enjoy as it is(u know there in't much room for upgrade on KWA's product)
Not the quickest responce but if you don't need crazy like full auto like with semi auto, it is really great aeg.

In conclusion this is not for the game, but for the personal trainning.

Anyways, I really love this aeg.

"I would like to start my review by saying this is NOT a beginner gun. It is one of the best ERS rifles on the market with some great performance for a ERS.(ERS= electric recoil system) this rifle has the same reliable kwa 3 gearbox that’s in the ronin t10, it has great ergonomics due to the 20mm rails and the pts EPG and EPS (pts brand enhanced, polymer stock and grip). If you are looking for a milsim gun that has a working last round hold open and is a recoil simulated gun, but you don’t want the maintenance of a GBB then this is for you. I have put this gun through 15+ days on the field and shot over 3k round through it without any issues other than the trigger stiffening up and having to shoot at once on full auto to get it to work again(this wasn’t the guns fault I was using 7.4v I recommend 9.6v or 11v. Overall very realistic feeling and looking replica. if it’s worth the money is up to you I’m just a random person on the internet. Don’t feel like making a pro con list sorry : )
But I do hope my review helped someone

"Very durable gun, love the full metal. Has pros and cons.
Pros: durable, rugged, very realistic feel and look, comfortable in the hands. Recoil feels great when slinging bbs.
Cons: lower fps(even after checking compression, various bb weights, and cleaning) bolt catch latch broke first day. Very very difficult to get factory muzzle brake off. Heavy, but expected. Will lock up and jam every now and then, throw on full auto, get a round or two out and then flip back to semi and you are good. Hop up is not very responsive to changes.
Overall a good gun and a good purchase. Be aware of FPS problems and occasional jamming. Did okay in the field for first time.
