    Our take:  The G&G Combat Machine M4A1 Carbine is an excellent high-performance Airsoft AEG rifle that can fight head to head with more expensive rifles in any Airsoft gaming situation, with an amazingly affordable price tag!  It comes standard with a 6-point retractable rear stock, which makes it extremely versatile indoors and out.  With the stock fully retracted, it packs a fierce punch in indoor/CQB games meanwhile with the stock fully extended, it can still run with the big boys in outdoor games.  With a muzzle velocity that easily overpowers Tokyo Marui AEGs and a reinforced high performance full metal gearbox, the G&G M4A1 Carbine is one of the best full auto M4s under $200.  It has been engineered to be compatible with Tokyo Marui and many other aftermarket upgrade parts, and thus it is a modular platform on which customizations and upgrades can be done with ease.

    G&G has reinforced the build ofthe gearbox to be on par with their more-expensive "Top Tech" line of $300+ AEGs, making this Combat Machine M4 an amazing value.  The gearbox works harmoniously with the G&G high torque motor to deliver OVER 800 ROUNDS PER MINUTE on fullauto at OVER 330 FPS.  Add a precision crafted barrel that enhances accuracy and minimizes barrel wobble, and you have an amazingly SOLID fully automatic M4A1 AEG at an unbeatable price.

    - Shoots over 330 FPS, compared with only 285 FPS by the Tokyo Marui M4A1 AEG (priced @ $270+)
    - This AEG is 100% compatible with Tokyo Marui parts
    - Enhanced high-performance full metal gearbox/high-torque motor
    - Semi/Fully Automatic firing models with functional safety
    - 450rd high capacity magazine comes standard
    - Adjustable hop-up is integrated into rifle design, along w/ 6-point retractable rear stock
    - Full metal barrel assembly for a solid build
    - Adjustable sights; removable carrying handle (once removed, the weaver rail is exposed for simple scope/optics mounting)
    - This M4 is extremely versatile and will dominate in any game, be it CQB (close-quarters combat) or outdoors
    - Battery and charger not included
    - BOTTOM LINE:  If you want a gun with the same HIGH-END equipment as the Tokyo Marui M4A1, but with EVEN MORE power and accuracy AT LESS THAN HALF THE PRICE, this is your BEST BET, GUARANTEED.

    For maximum performance, we recommend a 9.6v mini/nun-chuck style battery.  8.4v mini batteries will also work perfectly with this rifle.  For safe and quick charging, an universal smart charger is recommended.

    Operation:  Electric Automatic
    Firing Modes:  Semi-automatic and Full-automatic
    Muzzle Velocity: 325-345 FPS
    Magazine: 450-round high capacity (gear wind-up)
    Gearbox:  Full metal
    Hop-up:  Adjustable
    Weight:  6 pounds

    Ammo type:  Seamless 0.20g or heavier (0.23g, 0.25g, 0.26g, 0.28g, etc) BBs.  For maximum performance and accuracy, Airsoft Megastore recommends GoldenBall ProSlick BBs which carry perfect spherical consistency and density, available at Airsoft Megastore for the lowest price on the market, guaranteed.

    Package includes:  Rifle, 450-round high capacity magazine, pack of 1,000rd G&G 0.20g BBs

    NOTE: This AEG DOES NOT come with a battery or charger. We recommend using a smart charger when charging airsoft AEG batteries.

    Beautiful rifle.
    By: Rob Keefe

    "I got this gun around 4th of July, and I could not be more pleased for the price I paid. With only a $30 tightbore barrel, the gun shoots 415 FPS at 900 RPM. It's DEADLY accurate out of the box, and with no upgrades, people will call their hits 99% of the time out of mercy. It is highly upgrade friendly. If there's an M4 upgrade you want to put on, it will almost surely work in the gun. I actually prefer the polycarbonate body to metal, due to it's weight and versatility. This is an AMAZING gun for the money, and is a beyond amazing if you upgrade it. PROS: Price FPS ROF Upgrade friendly Polycarbonate body CONS: Front sight is non-removable Handguard is a total PAIN to get off till you have the gun for a little while Flash hider is deviously challenging to get off. I seriously melted it off with a MapTorch. "

    G&G Combat Machine
    By: Gamesrock22

    "I didn't get this gun from this site, I got the tan version from airsoftgi. This M4 is amazing. with a 9.6v battery, the ROF is insane. FPS is perfect with hop-up setup correctly. 125 Ft should be the max range of this rifle. Pros: Insane ROF(with 9.6) Fps is perfect for woodland and CQB(.2s only, dur) 450 rd hi-cap -it loads like 30-40 in a good wind Gun made of Polymer -Lighter, more durable, and more stronger then metal (like jg m4s) Adjustable Stock Removavble carry handle Cons: Delta ring is stronger then other m4s(you'll get used to it) Doesn't come with battery Mag kind of wobbly(electrical tape will fix it) Stock has VERY little wobble(not that much of a problem) Not lefty friendly(im lefty) Charging handle doesn't open dust cover(need a good finger nail or a piece of paper to open it) Overall: Pros definetly out weigh the cons Very durable gun, perfect for any situation a good 9.6 nunchuck will do the job Conclusion: GET IT NOW OR GTFO"

    Wonderful Gun
    By: Infantryman

    "This is a great gun! It is very durable and the magazine is without feeding issues. Pros: Good feel Durable Good ROF Perfect for CQB Cons: Battery case is sort of hard to get open (minor) Tiny bit of mag wobble Tiny bit of stock wobble Great gun, great buy. Gun comes with 1000 BBs. No sling or battery, but you should get a good one of Amazon.com, they have better prices on batteries than ASM Get this gun! Keep up the good work ASM "

    buy @ airsplat
    By: afsd asfd

    "the airsplat people upgraded to tightbore (6.035mm) and it's free shipping above $50 so i would buy this from there. Bottom line, this is a great gun that's way better than any of the DBoys, CMYA, and AGM guns."

    By: Will

    "It is a great gun. Ive used it before in a few battles and didn't have a problem. The mag can be a bit finicky but you can buy a spare. All around good gun and it will probably be my next purchase."

    Awesome Gun
    By: Ilian

    "I just got this gun yesterday. I put on my red dot site. I adjusted the hop up and the red dot site and it works perfectly. I can easily shoot targets at say 50 even 100 ft. I recommend this gun to anyone who is looking for a good and reliable gun for under 150 bucks. It is a little heavy (I would say maybe 5 or 6 pounds with bbs) so I do not recommend it for the beginners. It is a perfect gun for CQB and even a little skirmish in the woods. I recommend using high grade bbs because it is a 140$ so you do not want to wreck it with low quality bbs. The bbs that you get that are G&G bbs are very good but you can also get Golden Balls because G&G do only give you 1000 so you might want a little more."

    Great gun
    By: Blaze Shadowthorn

    "It's a great gun! It's my first automatic gun and it hasn't let me down. The only problems I would say is the mags break. I've had to replace mine twice. Other than that, great gun, good range and power. "

    G&G M4
    By: Devon Silva

    "Excellent design, it may be plastic but its of the reather durable kind. The only problem i have with it is the loose fitting of the magazines and feeding issues. I have done some research on this and it seems that it happens to be a hopup problem, apparently it works flawlessly with mid caps but it giuves problems with hi caps. But other than that an amazing gun."

    no battery no buy is completely wrong
    By: chris

    "first off this gun is awesome my friend has had it for 2 years, we go to airsoft courses together, it has seen everything and still works like a charm. no upgrades or anything and shoots 350 fps with .20s besides the CYMA ak47 for 1 thats a terrible brand, their guns break in about 2 months or so. its worth it if you have the money"

    No battery...no buy
    By: Daniel

    "Everyone says this gun is awesome, and I won't disagree, I'll just ask a question. Why buy this when you can get a full metal CYMA AK47 that has a higher velocity, full metal construction inside and out, 600rnd mag, A BATTERY, and then some, all for LESS money (when you include the price of missing battery plus charger)? I was very intrigued by this gun when everyone said its the best one under $150 (I want to get a couple beaters so my friends can play and get addicted ;) ). But it DOESN'T cost less than $150, as you have to buy a battery for it. I've held this gun, and its solid, but the lack of a battery is a big downer when there are comparable (arguably better) guns out there for less. "

    Combat Machine for beginers
    By: Alexander Wodell

    "Well the gun is very durable and it has a good rate of fire, the accuracy is pretty good and the sights are xet perfectly. There were only a few bad things i found about it. the fuse it came with went blew really quick and the magazine's wheel on the bottom was slipping. over all an average gun for the beginer"

    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
    I loved buying from airsoft megastore because the employees helped me recover my tracking number and told me where the package was at, I would love to buy from airsoft megastore again! Battlefield4Rule, USA
