Our take: The NEW Cybergun Fully Licensed M4A1 Carbine AEG is a versatile rifle out of the box and is built to perform at the same level as other high performance AEGs in both indoor and outdoor fields. This rifle, which is fully licensed under Colt's Manufacturing Company (CMC), boasts a polymer body with a FULL METAL gearbox and includes TWO High Capacity magazines! Firing at 340 feet per second (with 0.20g BBs), this AEG can take down targets at ranges up to 190 feet, making this carbine perfect for long-range outdoor fields.

The Cybergun M4 Carbine is also ideal for indoor CQB scenarios, thanks to its collapsible LE stock, shortening its overall length by about 4 inches. At only 30 inches retracted, this rifle is tactically designed for clearing buildings and maneuvering in confined spaces. Hidden beneath the rifle's extremely rugged polymer body is a hard hitting Version 2 metal gearbox that performs at nearly the same level as more expensive M4 AEGs! 

Another versatile feature of this M4A1 Carbine AEG is its removable carry handle, which exposes a long top optics rail, allowing you attach red dot scopes, magnifiers and other aftermarket optics. If you're going for more of a streamlined look, you can keep the carrying handle attached and use your front and rear iron sights, which are fully adjustable for windage and elevation. The rear sight also offers two sight stations, with wide and fine apertures that help with target acquisition in outdoor and CQB environments. Additionally, the M4A1 Carbine comes with a full metal outer barrel that adds to the rifle's overall durability.

This high-powered AEG comes with everything you need to field right out of the box, including battery, standard wall charger, TWO High Capacity magazines and bag of BBs. If you want to pick up more magazines, grab this pack of five 300-round M4 airsoft magazines at an affordable price (it also helps if you have a roll-up MOLLE dump pouch for spent mags). With fully licensed Colt trademarks, a collapsible LE stock, full metal gearbox, and more than modest FPS, this rifle is must-have for any player looking for a great M4A1 AEG, that is field ready right out of the box!

Battery Charger Recommendation: 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.

Great gun!!

"I have had this gun for about two months now, and all I have to say is that it has shot by my expectations. It chrono's about 360-80 FPS with .2 GOldenBall BB's, and it is totally legal for CQB play. It is a polymer body but it's metal where it counts, and it has never failed to perform. However, the only thing I can say bad about it is that the stock seems to 'pop' off (for lack of a better word) after about 5-6 days of usage. However, it's nothing a little super glue won't fix, and other then that, I've had no problems with it. (Word to the wise: If you plan of getting extra mags, get the 300 round DBOYS mags, not the 70 round ones, because they never feed all the way through. I don't know if that's just my gun, but it only shoots about 40 ish and then it stops firing, even though there are BB's in it. If you play MilSim like I do, get the high caps and only fill them up with 70, trust me, it works 100 times better)."

Amazing gun

"Ive owned this gun for a year now and still fires like its new. I have been using the standard 8.4v battery and it lasts surprisingly long and the fps is excellent. I cant imagine this gun with 9.6v battery. The gearbox puts out atleast 360 fps with .2 bb's and gets a good distance. This gun is compatible with magpul aftermarket parts and they look great with this gun. Alltogether its definately worth the money and this gun will not let you down as its very reliable."

Great for the Price

"My friend uses this gun and I had the chance to try it out. Cons: A bit on the light side. Pros: Shoots very smoothly, a lot less trigger lag than my G36C. It seems solid, and while it ought to be heavier, it is pretty accurate and fires fast, especially with 9.6V. Verdict: Good performance for the price. I'd definitely recommend it."

My first AEG.

"This gun was my very first AEG, and let me say it was a great starter. First off, because of its engraved Colt logos make the gun look and and feel authentic. I was impressed by the power of this gun, probably reaching more like 380-400 fps with .20s. It feels fairly weighty, but not to heavy making it easy to sprint and jump around with. It came with two very nice 300rd metal mags, and a cleaning tube, which is nice. I love the adjusting stock of course, with is nice whether your in CQB or the outdoors. I got a bungee sling which works nicely with it, as well as a smart charger with a red dot sight AND a rubber training knife/bayonet which will fit with this. My only complaint is that after a while the stock got wobbley, but that is normal with M4s after a while. If it does get loose, I used an Allen Key taped to a wellrod to tigten it as the allen screw was deep in the buffer tube, which was a pain. In the end though, this gun is worth it, I recommend it, I want to put a RIS on it next though! Im thinking of investing in a RIS system for it probably the Golden Eagle 6.5" once its back in stock as well as different attachments if it works.( Any recommendations for RIS systems for this gun that would match color wise and length?)"

Colt M4A1

"This is a really good gun for its money and would recommend a 9.6 battery because it has a low rate of fire with a 8.4 battery. Pros decent fps, good rate of fire with 9.6 and can play outdoor and indoor. Cons plastic body and low rate of fire with 8.4 battery. Buy the 9.6 battery!"

The store is amazing. I have found there items that I could not find in other stores which makes it the best. I have made questions and inquires about products and the customer service has responded super fast with accurate answers. All my products have arrived in excellent conditions in spite of other stores. My last product came late because it was rescheduled but that was UPS fault I think. I would like to thank Matthew for his exceptional customer service. Whenever you need help, please try to contact him. My advice, buy in Airsoft Megastore, they have coupons and the widest variety of airsoft products. RandyLoy, USA
I ordered a gun sling a couple weeks ago. Unfortunately, one of the clips broke. After a few email correspondings with a customer service representative named Jun (my emails did not show a last name), AMS sent me a replacement sling for free. I did not even have to send my clip back. AMS is a terrific store and I plan on doing more business with them. They were polite, efficient, and just a pleasure to work with. I would recommend Airsoft Megastore to anyone. mskanwischer, USA
Airsoft Megastore is The Best Airsoft Website Out There (I Think) and i Will Always Be Loyal to AMS and Order Almost All of my Gear From Them. The Customer Service is Also Amazing, Jun my Customer Service Representative Has Helped Me With Anything i Needed Help With, Especially My Order Problem (Had 2 Magazines Missing from Order) and Jun Helped Me With The Problem, and Now The Mags Have Been Shipped To Me. Thank You So Much AMS and Jun. Ethan1214, Saskatchewan, Canada
I love that Airsoft Megastore has videos of most any information you will need to learn and care for your products. I purchased an AEG for my son and in short order, unfortunately, it began grinding after brief use. I emailed for warranty repair with symptoms and with 24 hours (22 to be exact) I received an email explaining possible causes with a video like for tuning the gun. I had the gun working again within 15 minutes, avoiding returning the gun and the mess associated with returns\repairs. Excellence on Sean's part to help out a first time customer of theirs. Highly recommend. bucfanjeff, USA
Everything worked great, shipping was super fast. I am very pleased and won't hesitate to order through airsoft megastore again. rob_riley, USA
