Our take: The A&K M4 CQB AEG is part of A&K's line of performance oriented, quality CQB AEGs. These polymer-receiver A&K AEGs are built to be high speed, and perfect for close quarters Airsoft combat. These A&K AEGs not only feature lightweight and durable polymer bodies, but also include everything you will need to start using the rifle! The A&K M4 CQB includes a rechargeable battery, a standard wall charger, a 300rd high capacity metal magazine, a tactical fore grip, two rail covers, and a metal replacement flash hider! The M4 CQB AEG has great range despite its compact size, shooting accurately over 100 feet! The M4 CQB AEG is the best choice for close quarters battle, due to its compact size, lightweight frame, and high rate of fire.

The M4 CQB AEG features a fully adjustable 6 position tactical crane stock, making this AEG more maneuverable and well adapted for close quarters combat. This M4 CQB AEG can also easily hold its own in an outdoor environment. With a precision inner barrel and fully adjustable two-piece hop-up, it can easily hit targets beyond 100 feet! The M4 CQB AEG features a high-quality impact-resistant polymer upper and lower receiver, a full metal rail system, a full metal outer barrel, and metal front and rear iron sights. The full metal rail system is crafted from lightweight anodized aluminum, and is perfect for attaching a variety of tactical accessories and upgrades. The polymer components on the rifle are the retractable stock, carrying handle, and the motor grip. The A&K M4 CQB's construction is extremely durable, and has an ergonomic feel and realistic weight.

The A&K polymer body M4 CQB AEG has a redesigned and reinforced metal gearbox with a factory installed high speed motor, making it one of the best-performing  polymer body M4 AEGs on the market for under $150! The full metal gearbox features metal bushings, a metal ball bearing spring guide, a full steel gear set, a high speed motor, and a perfectly sealed cylinder. The A&K M4 CQB also features a two-piece hop-up unit as well as a 6.04mm precision inner barrel, providing excellent range and accuracy. The M4 CQB AEG can easily hit targets at over 150 feet away!  

Overall, the A&K M4 CQB AEG provides the best value for the lowest price on the market. With a solidly constructed full metal high performance gearbox this AEG is able to hold its own against some of its top tier AEG competitors. The A&K M4 CQB provides great accuracy and hard hitting power in a compact carbine size platform. If you are looking for a lightweight CQB AEG, but can't afford the top tier price tag this is definitely the AEG for you!

Package includes:  A&K M4 CQB, 300rd hi-cap magazine, a vertical foregrip, 2 x rail covers, rechargeable mini-type battery, standard wall charger, and cleaning rod

Battery Charger Recommendation:  Although this fully automatic airsoft rifle comes with a standard wall charger to charge the battery, Airsoft Megastore recommends the use of a smart charger to avoid overcharging the battery(overcharged batteries may cause decreased airsoft gun performance and may shorten battery life significantly).  Smart chargers not only shorten charge time significantly (up to 800% faster charging), but more importantly,also automatically shut off once the battery is fully charged to avoid overcharged batteries.

5 390 FPS A&K Airsoft M4 CQB RIS AEG Rifle - Full Metal Gearbox *****
:D

"Wow, this gun is GREAT! It's FPS is OK, but with a spring change it's hitting 400-420. The battery is good, but I'd recommend a 9.6v 2000mAh. Anyway, enough with that we'll go through the pros and cons. PROS- EXTREMELY durable, high RoF, OK FPS, feels real, weighs real, 6 position stock. CONS- not completely metal, needs some upgrades (but when you get them it outperforms some of those WoM (waste of money) 300$ guns), grip that comes with it is bad (but it's free). And to the guy who gave it 3 stars because it didn't come in the original box but the gun was great...get out."

EXCELLENT GUN !!!!!!!!!!

"This is my second gun,I love it !!!! I'll reccomend to this gun to anyone.The only problem I have with this gun is it sometimes get jammed,but only a few times. I've had the gun for a year now and its gotten jammed twice only its had no other problems. All I had to do was pull the charging handle and it unjammed."

Great gun for any player.

"For the money you're spending, it's a five start no doubt, but it's no super pro gun. Disregard all reviews saying it's full metal, it's most certainly not. Every rail on the gun is metal, the outer and inner barrels are metal, and the the sights are metal. The rest (Upper and lower receivers and stock) is made out of very strong and durable ABS Polymer. I put a 9.6v battery in mine and it shoots very fast and very hard so I suggest getting one if you don't own one. The hop up will have to be adjusted as it comes preset on the the highest setting and just shoots bb's upwards. Pros: Strong body, removable flash hider (annoying to get off...), metal rails, accurate, powerful, good for CQB, long range and mid range. Cons: Flash hider is very hard to get off, battery is ridiculously hard to get in (unused to crane stocks), barrel is loose as with every M4 (can be fixed with 2 O-rings or epoxy, check youtube). I would recommend this to anyone who is looking to advance from beginner to intermediate guns or to a pro looking for a very customizable CQB M4 at a great price."

"Overall this AEG rifle is great, I recommend you buy it since it's on sale and it has a good performance. Also the either things that is good about this gun is that well it's like in the middle of heavy and light, so it feels like a pistol you are holding in the war but just bigger. I found nothing bad about this gun so it's pretty good, unless you aren't really going for the rifle."

Awesome

"I got this gun 2 months ago its a very good gun. I have used it in an match and it worked great. we played for 4 hours and it didn't die. It jammed but if you go automatic it unjamms itself. Putting the battery in is a pain but it's still great, every thing is metal :) (almost). Great rof and shoots accurate. I got 8 extra mags for this (midcaps) they feed so well i would never trade or buy another gun."

A&K M4

"Overall I would say this is a great gun, it has a good weight to it along with good maneuverability. The battery lasts for just about as long as you would need it to, and the rate of fire that it puts out is very nice. You will more than likely need to adjust the hop up once you get it, but its really not that much of a chore. The only thing is that the RIS surrounding the barrel wiggles a tad, but it doesnt make it any less solid. Overall, I would definitely get this gun. Installing the battery was a bit of a pain, but you just have to work with it and it should slide right in.The only thing I would recommend is that you buy a smart charger, that way you don't overcharge/fry the battery."

Great Rifle!

"This thing is outstanding! Just got it two weeks ago, and still firing great. I shot two mags every day for a week and still holding up. The upper and lower receiver are made of Polymer, while the rails, sights, handguard, outer barrel and buffer tube are all full metal. The first thing you'll notice when picking this thing up is its weight. The gun is extremely heavy, so I suggest changing the handguard for a lighter one. With the hop up turned off the gun shoots accurately for about 90 feet then drops off very quickly. Great airsoft gun for close to med range combat. Got this on sale for $103 (very cheap) lucky for me. Great gun, probably the best I have so far! hope this helps."

Review

"i got this gun about a week ago and so far its pretty good. the bbs in the mag run down pretty fast so i recomend getting a second mag. when you pull the mag out, a bunch of bbs fall out which is a waste. the gun comes with enough to fill the mag. one of the cons is that i almost broke the stock trying to figue out how to get the battery in because the gun doesnt come with a manual, so i went on youtube and looked up the gun name and they show you how to get the battery in. i would also get a 10,000 rd bag of Goldenball bbs for maximum accuracy. but overall its pretty good. if i could go back a week to pick out a gun i would pick this one!"

"Extremely reliable, replaced with a 6.01 tight bore barrel. I'll soon be putting a metal body with it. The bad thing about this gun in my opinion is the battery it comes with is hard to put in. So far best M4 I've handled"

Missing something

"The gun itself is really good, I have no complaints. But when I got mine, it didn't come in the original box and was missing the instructions."

I love the pro gunbuilder by golden eagle!
The gunbuilder was very useful and made it easy for me to buy my first mid/high spec gun for just about $300. It gave me comfort in that i can get more parts to switch out at a later time if i wish to change anything about my rifle and that there will be compatible parts for any modifications i choose to do on it. The gun came in full working order and the hopup was even adjusted to be perfect right out of the box. I could easily hit targets over 150ft away constantly. Johnmstopka, USA
