Cybergun x Colt Sportsline M4 AEG Rifle w/ G3 Micro-Switch Gearbox (Model: M4 SBR w/ 5" Quadrail / Black / Gun Only)

"Threading on this one is clockwise. Otherwise it's a nice little gun and the package is well worth the money.

"The gun is amazing! Its all metal it looks amazing and in fired great. However there were some complications. One being that the hop up seemed loose but i just tightened some pieces and it was fine. The stock was a bit loose but wasn't a big deal. My major concern was that when i took the orange muzzle brake off to put my metal one on all of the ridges on the barrel of the gun were smashed. i was a little disappointed at this but i might be able to fix it with some tools. Other than than these little problems it was a great buy and i cant wait how to see it works when i upgrade it.

Pro's
Full metal, Fully customizable, great handling, Tight pieces, ect...

Con's
Loose stock, smashed grooves where muzzle brake was, Mag is hard to push in but once its in its not gonna be loose or fall out so could be a good thing, doesn't come with battery. All of these are very easy fixes other than the muzzle grooves.

"Pros- the m4 is a very light weight gun

Everything I the package is a great deal

Accurate

Long range (with the right hop up adjustment)

Cons-
The red dot needs a riser

The Handel gets hot

The barrel got jammed on the second day but was easily fixed

"This weapon package is absolutely excellent for the price.

To begin, although this is a relatively small gun and clearly meant for CQC, I have used it exclusively in outdoor games in the forest. And it's range was very satisfactory, I'd say at least 120 feet or so is where you can shoot it accurately, and I was using .23's, so a slightly higher weight might actually make this better. I personally like to sneak up on people and get fairly close to them, so it perfectly matches my style because of the lack of excellent range.

Overall, for the pros, the weapon performed beautifully, almost never malfunctioning. It shoots consistently and hard, I've left welts on people with this thing. It is very light, and the material feels good to the hand. Batteries both function well, as does the smart charger. The hop up is ridiculously easy to adjust, in a good way.

Onto the cons. The red dot is slightly inconvenient, as the weapon does not come with an easily removable front sight, and also the green dot settings do not work, might've just happened to get a bad one though. It does seem like it would function well if attached though. The peep sights are difficult to aim at people in even a slightly dark setting, and the front sight is not painted a different color, making it very tough to distinguish from the target. I painted the front sight a reflective metallic color, which helps slightly, but the sights are simply not great, which is a pity because I'm the type of player who tends to run on semi rather than auto. By the way both semi and auto work beautifully on this gun.

In addition, the port cover was broken and could not be closed when I received the weapon. About a week ago, I was packing the weapon up the night before a game, and noticed that the little lever thing that lets you adjust the stock length had vanished. I do not know how to adjust the stock manually now, but it is sort of ok just because I am a small guy. Despite that, the gun is very sturdy, I've dropped it on hard dirt once and it took it like it was nothing. In addition, the mag release button is very sensitive, and mags will drop out of nowhere occasionally, so be wary.

Overall, don't be deceived by the fact that my cons list is larger than my pros list, the gun simply operates as it is intended to, so it works very well.

I would definitely recommend this to a friend if they wanted to get one.

"great gun totally worth it

"I got this M4 from the 2014 Box of Awesomeness "perfect gift M4" edition. The rifle came with a collapsible crane stock w/plastic buffer tube, a removable carry handle rear sight, one hicap mag, one BAMF midcap mag, a 9.6V matrix butterfly battery w/ small Tamiya plug, a valken tactical smart charger, and a manual for an S&T M4A1. The rifle has a functional bolt catch, its main purpose is to hold the faux bolt plate back just enough to give you access to the hop up unit by pulling back on the charging handle . The hop up unit is not like your average M4 unit, but more like an AK-style hop up unit. So rather than turning a wheel; the hop up is adjusted by sliding the dial from left to right and right to left. I'm impressed that the M4 is light weight due to the polymer upper and lower receiver, the outer barrel is metal and has a +14mm clockwise thread (description says -14mm negative thread). The rifle has a metal version 2 gearbox with a red inner barrel. The issue I had with the rifle was that the barrel nut was not aligned properly. When I replaced the hand guards with a quad rail, I noticed the top rail was not flush with the rail on the upper receiver.

This AEG is great for beginners as an M4 starter kit with what is contained in the box.

"First, I want to start off by saying, I am an experienced tech, and even though this was my first good airsoft gun, I have learned lots about airsoft and particularly AEGs since I have bought this gun.

Anyways, it is a pretty basic m4. Wired to the front with 16 ga wires ( good), and small tamiya connectors, as well as a fuse. It has a polymer body, but don't let this deter you from buying. It decreases weight, and is still VERY durable. I have dropped it many times and it still works fine. I only had two problems.... The first is very minor but still present. This gun has a really weak bolt return spring, and one time when I pulled back the charging handle, it stretched out and snapped. All this means is that when I pull back the charging handle, I have to push it forward instead of releasing it. Once again, no biggie. The second though, is kinda bad. The outer barrel became very loose after moderate use of play, and I couldn't figure out why. I later found out that the barrel nut, or barrel star, was loose, but is too sharp to turn by hand, so I had to blow $50 on a armorers wrench, but you will need that anyway if you are going to modify and m4. That fixed the wobble for now, but I haven't skirmished yet after that, so I'll see how it holds up.

Pros:
Good fps
Good ROF
Polymer body,( lightweight)
Good wires
Great stock 6.04 mm brass barrel.

Cons:
Heavy ( for some people)
Slight barrel wobble at first
Weak slide return spring

Over all, this is a great gun. Good price, especially for the package. One thing I forgot to mention is that the 4 mags that come with this gun work great, but I've found the 3 flash mags wind quicker and more efficiently than the factory direct aim top mag.

4/5 stars. GET THIS GUN!

"This gun out of the box looks and feels great. There is a bit of wobble on the hand guard but nothing to worry about. The package is supposed to come with a 9.6 v butterfly battery but mine came with an 8.4 volt small brick type battery. Other than that it was a good deal for the package at the epic deal price of $160
Pros:
Great gun with every thing you need (excluding eye protection) for a great price.
Gun feels good is your hands
Every "major" component of the gun is metal
Shoots very nice and accurate

Cons:
The gun came with an 8.4 volt battery instead of the promised 9.6 volt battery
There is a bit of wobble in the hand guard
rof is slow
The flash mags don't slide out to easily when you press the mag release

Verdict: great gun for the epic deal price $160 but i personally would not spend 280 for the package. You get a great Aeg and can upgrade it if you want later.

"The gun looks great a bit of wobble in the fore grip is shoots good sometimes it locks up when u shoot semi auto just switch to full auto and it should fix that the only reason I made this a 4 star and not a five was because the reviews is on the package deal not just the gun when I opened the box to my surprise bbs fell everywhere the bag of bbs had a big cut across the middle and the bbs were everywhere In the box and then soon my floor
pro's
- sweet looking gun actually heavy kinda
- the receiver actually resembles metal

Con's
- the gun locks up a bit on semi-auto
- the bbs all over the place

definitely a good buy if your on a budget I would recommend getting a battery so u can play all day I will upgrade this review in a week or so going to a big game next week I'll see how it performs this is also my first aeg

"Pros
Complete package good for beginners
Charger is good
Ok rof and fps with .25s
Cons
Full metal and slightly Heavy after a few hours

"It’s a ok beginner AEG…when it works/isn’t broken. Since I got this for my son it has been nothing short of a pain in the…you get the point. Day 1, the motor was not seated/came loose after ~150bbs. Made this extremely awful whiring/grinding/screaming sound. Sure easy enough to fix with a quick adjustment but to an airsoft rookie. Good lord that’s not what you wanna hear after dropping $200 and waiting in excitement for a week. Then things were going good for a few weeks and we had to do a spring change for a different field. This shoots about 370ish out of the box with .20’s. So in goes the new spring and all is well. Then we add the original spring back in and one of the ears on the spring guide snapped off. Lack of quality part and owner error to be fair. But the kicker was this thing uses a S&T armament gearbox and well finding the correct replacement was not so fun. Evike carries it buuuuut good luck finding it in stock. The polycarbonate replacement they have for like ~$10 did the trick and it’s back up and running. Oh also worth mentioning the buttstock battery cover plate had the ears break off on first game. So now we have to keep it together/retain the battery with a Velcro strap. It’s just not worth all the headaches it has caused. We have a matrix Mk18 that was less money, shoots 400fps out the box, that was purchased 5 days after this one and it has had ZERO problems and had the exact same treatment. So while this thing is good when it works and garners a 2-3 star from me. I cannot in good faith recommend it in 2025.

"i bought two of them and they are very good but one problem is that one of them didn't fit into my gun unless i slammed it in and hit it but when in they shoot like butter not one missed bb

"Pretty good but the rail doesn’t work with normal attachments. It wasn’t machined to high enough standards I guess. I had to use a halter to get a grip to the position I wanted.

"Well guns great out of the box and I ordered the package that came with extra mags. The two extra mags given don’t even fit the mag well. They slide in but they don’t clip in they just slide in and out. I’m confused on why an airsoft company doesn’t even know the proper magazines for the gun. 5 star gun 2 star package.

"It's OK
The build quality is expected for the price. There is ZERO METAL on this AEG.

PROS: price
Range
Build quality
CONS: May or may not work out of the box. When I took it out of the box, I only got three shots before it stopped working. One of the wires in the pistol grip was COMPLETELY SAWED IN HALF.

Overall, it's a good starter gun
