"Got this a while back, have used it at many fields and has been my main gun for a year now. Got out of the sport for a while and wanted to get back into it. Found this guy in the Airsoft go package. Red dot is a little wobbly, and the extra mag they give you doesn’t fit or feed. Aside from that, very solid gun. Good weight, durable. I had my selector pop off but was an easy fix. All in all great gun for new players or old. Would recommend this to anyone who is on a budget but looking to get into the sport.

"great trigger. responsive. accurate enough. only four stars because polymer mags do not work on this gun. I have tried 4 different brands of polymer magazines including Evike BAMF, Matrix, G&G, and some unknown brand. Only magazine that will lock in is the metal one that came with the AEG.

"I bought 3 G&G polymer 120 round mid-caps and they do not fit into this gun very well at all.
What would be a recommended mid-cap magazine for this gun? Looking for a magazine that is easy to click in and fits good.

"(updated review)
I bought the "Black M4A1 | 350 FPS" version.
I have owned this gun for one year now and used it on the field twice and both times it served me well. One of those times it jammed, but nothing catastrophic happened. The motor height had to be adjusted.
PROS:
Super high RPS (17 w/ 9.6v)
Good trigger response
Lightweight
Made of polymer (super good quality polymer)
Stock gears are INCREDIBLY durable (no teeth stripped despite not being lubed/cleaned)
Piston has full steel teeth
Easy to adjust hop-up
MOSFET built in (lipo ready)
Can hold down full-auto for a long time with motor/battery heating up (only do it with a 9.6v though)
Quick-change spring guide
CONS:
Bad shim job
TERRIBLE compression system (this results in much lower FPS)
Cannot install Gate TITANs
Tamiya adapter
Slight stock wobble (to be expected with most stocks)
RECOMMENDATIONS:
Replace gearbox with one that can accpet Gate TITANs (this one does)
https://www.evike.com/products/38256/
Replace compression system
https://www.evike.com/products/54606/
Reshim with steel shims

"Had this gun for about 3-4 months now. I’m new to airsoft but I
recommend this gun to new players like myself. Very accurate and affordable. I would suggest using semi auto only with this gun.
PROS: - very accurate. This can shoot between 30-40 yards
- easy to change battery. I hate the handguard wired M4 but
that’s my opinion.
- Detachable iron sight/carry handle. I bought an AR-15
scope for it and it worked very nice and was able to
get 30-40 yard shots on it with the scope.
CONS: - DO NOT use full automatic constantly!!! This gun broke
because it broke after using full auto to much.

"I’m pretty happy with my purchase, the m203 feels like it’s a bit loose, but other than that it’s a great gun.

"This is my first AEG as I bought a pair of them to train with, as I'm a real gun user. I must say, I'm impressed with this carbine and I'm glad that I made the purchase. My only suggestion/complaint is that the picatinny rails are not real picatinny as they are wider than true mil-spec picatinny. I have a lot of picatinny attachments and I had to mod them for them to fit on the rail for these carbines. Oh, I suppose I have a second "gripe" as the grip has a space that rubs on my index finger. I'll probably smooth it out or fill that space, so that it's smoother.

"I ordered the 8" URX version in Black.
Overall the performance was amazing. I paired it with an 11.1v LiIon battery and the ROF skyrocketed! The iron sights were extremely stiff and required some grease to really get moving smoothly. The metal components are the internals, trigger, mock bolt, dust cover, Handguard & rails, outer barrel & inner barrel, and front iron sight. Its lightweight but still has a realistic feel and looks amazing. I would definitely recommend this AEG for any new players as it comes with a MOSFET and ETU which are vital upgrades for airsoft. However I do recommend that you be cautious as I received mine with a broken Hop-up Bucking. This didn't matter however since I planned on Flat hopping my gun with a new bucking and nub. Not only that But mine averages an FPS of 463 with .20s. which is illegal no matter the Field near me.
PROS:
- High ROF
- MOSFET and ETU
- Easily upgradeable
- Quick Change Spring
-Metal Hand Guard and internals
- Adjustable Stock
CONS:
- Illegally High FPS (463 FPS w/ .20s)
- Came with torn hop-up bucking
- Nothing else
TLDR
Its an awesome gun just be aware that it could come with some broken parts so be sure to use the warranty. Mine came with Extremely high FPS so dont expect below 390-400 FPS. Its good for beginnners.

"Over all for the price point the gun is decent, I was disappointed to find out contrary to the specs on evike it is not front wired
That’s really my only complaint

"So first off, I'm an airsoft tech, and I had a customer who wanted a cheap, high speed build for indoor airsoft. I bought this because of the way the listing touts the gearbox as a magical performer for the price.
Upon opening the gun up, I have a few cons to go over:
-"high torque" motor is not a high torque motor. I think it's about 10-11TPA at most.(I bought a 12tpa high speed for the build and it has more torque)
- The microswitch trigger/mosfet combo has a semi-auto rof lock, preventing you from spamming the trigger really fast similar to an ARES mosfet/ECU. (although this may have something to do with the wiring)
- The wiring in the gun is 18 or 20 guage, which is too small for an airsoft gun. I mostly work on G&Ps, and the 16 guage wiring lowers resistance so much more, allowing for better motor and mosfet performance.
- The piston head is key-locked into the piston, preventing you from changing the piston head out for a high-speed one like the tienly head. The piston head also causes a leak in the airseal, making it not so great, even after changing literally every other compression part.
- Almost no grease in the gearbox, and NONE on the gears.
- The barrel and bucking are trash, the one I got had loose rubber inside the bucking and junk in the barrel.
- Pre-wired to tamiya
However there are many Pros to this gun as well.
- Lightweight, easy to sprint with
- Rail system is Metal
- Gears are strong and shimmed relatively well out of the box
- Microswitch trigger and mosfet are nice to have out of the box
- Gearbox shell is casted well
- Has a VERY strong tappet plate
- Stock has plenty of battery room
Overall, I would recommend this gun for anyone wanting to build a good indoors gun, because it is a nice, cheap platform for that. For someone looking for a gun that would never need work, or for a new player, I'd probably go with a new G&G combat machine over this.

"This gun works very well, but I do have a complaint regarding the design. The upper receiever is held in with a Pin in the front like the real thing, but the rear Pin doesn't do anything. The rear portion, right underneath the charging handle is held in using a short piece of plastic that slides underneath the stock. The reason this is a problem is because it pops out incredibly easily upon any type of pressure/drops, and to fix it you have to disassemble the gun to put it back in place. This is how I received the gun and was a bit dissapointed
Other than that, it's a great gun and I would recommend it for the price point.

"I would definitely recommend buying this set as a starter or if you are looking for a loaner to let others use.
I bought the 9" RIS starter pack. I have been using this gun for about 2 years now and for a starter gun, it is phenomenal. I started by using the .20g BBs, but this gun has a much better effective range with .28g BBs. It was also a great gun to learn how to tinker and upgrade internal parts (I have upgraded the bucking twice, but I think that is expected after putting about 10,000 rounds through each bucking). The red dot sight included isn't half bad either (highly recommend getting a protector for the sight lens). Next upgrades that I have yet to try are installing a Prowin Hop-Up and creating an R- or S-hop for the barrel.
I have had no issues with it, except for a few double feeds (maybe 3 or 4 times in the past 2 years) and the fire selector is a little too easy to switch between the SAFE-SEMI-AUTO settings (sometimes switched it into full auto accidentally when using my off hand).

"Got this gun on sale. It shots really well out of the box, I think they use a m130 spring. I have not looked at it’s quick change spring. I hope it’s easy and I don’t have to take it all apart. I think I like it as it is. But I want to buy another one in a few weeks and then upgrade that one with a m150 spring. I’m not sure if this one can handle the load. My aps broke down and I will never buy another aps again. But this one for the right price sounds fun and interesting. I have two other m4s that are elite force. I have upgraded them to thier fullest capacity. The aps I bought here for 179$ broke on me, they said dmr but I think not. It feels funny but I like the gun with scope and hand grip. Oh it doesn’t accept my elite force mags. The magazine is a little tight and not really well rounded for other mags. It did take my drum magazine that’s good. Thank you guys. From now on I buy cheap guns on sale. 110$ is a fair price. I like that it impressed me. I hope to order more of these kind of guns with m130 spring as I only play outdoors in Florida. Stay healthy team evike. Work hard work fast. Thanks again for fun gun.

"Gun worked flawlessly in store and then locked up at the field..
Took the gun apart and found out luckily nothing was broken, so I re-shimmed and re-greased the gun and it worked.
However during assembly I accidentally broke the screw inside the pistol grip and finding a replacement is becoming a pain. I've tried three different standard grips and nothing seems to line up with the receiver and the gearbox. Also the motor plate on the pistol grip leaves me on a bit on the offence as the motor is seated is a tiny grub screw.. Bad design.
The gun is pretty solid out of the box minus the bad pistol grip motor plate design but for all techs I would caution the proprietaryness of the some of the parts in this gun.
Will update later if I find a brand that is compatible.
