    Our take:  The newest JG M4 CQB-R has been re-tooled from the inside out, and has been outfitted with even more enhanced parts to better both reliability and performance.  Best of all, you can get this JG M4 CQB-R AEG for less than HALF of what you'd pay for a BONE-STOCK Classic Army, Tokyo Marui or ICS AEG.  Why get a Classic Army, Tokyo Marui, or ICS for $300+ when they perform at only about 290-340 FPS out the box?  The JG M4 CQB shoots harder, more accurately, and has a gearbox/motor set-up optimized for performance right out of the box.  

    - Full metal gearbox with reinforced metallic components for increased power and durability, coupled with JG's all new re-designed ultra high-torque motor for an unbelievable rate of fire of over 850 rounds per minute
    - Full metal integrated rail system for convenience when adding accessories such as lasers, lights, launchers, etc; adjustable rear sight also pre-installed on sight rail
    - Metal tight-bore barrel for increased accuracy and power
    - Metal 300-round high-capacity magazine included
    - Adjustable hop-up system
    - Tactical adjustable 4-point rear CQB crane stock

    QUALITY ASSURANCE:  Through numerous factory visits, we are able to confirm that JG tests EACH and EVERY single AEG that they ship out by putting each unit through a rigorous 16-point inspection, which ends with a Q.C. agent shooting no less than 450 rounds from the rifle to ensure quality before exiting the factory (hence sometimes buyers may find a BB or two left in their mag, as a result of the Quality Control agent's test firing).  This gives us even more confidence that JG is ever-increasing their attention paid to quality, and is a contributing reason to why the quality of JG AEGs gets better year after year.

    Battery Charging Notice:  To ensure safe battery charging, do NOT leave the battery in the crane stock when charging.  Always remove the battery, place it on a safe, non-flammable surface, then charge the battery.  Failure to do so may cause a fire/burn hazard to both the rear stock AND the battery/charger itself.

    Operation:  Electric Automatic
    Firing Modes:  Semi-automatic and Full-automatic
    Muzzle Velocity:  385-445 FPS
    Magazine:  300-round high capacity (gear wind-up)
    Gearbox:  Full metal
    Hop-up:  Adjustable
    Weight:  8 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:  Everything as listed and pictured

    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.

    Great Gun
    By: steve

    "This is an awesome gun for the price. It has a great rof, is pretty accurate and hits pretty hard down range. Would definitely recommend this gun to anyone. The only thing is, if you get an extra mag, don't get a Dboys mag. The Dboys mag rattles really bad and you have to constantly hold the mag up into the receiver for the gun to fire any bbs. "

    Awesome Gun
    By: Brent M

    "This is my first AEG. I am shocked at how powerful the gun is. It shoots flat out to about 150-200 ft. I have had it for 6 months now. Have sent over 20,000 rounds through it and Zero problems. The battery isn't hard to get in and out. not sure what all the other complaints are about from others. Great Gun. Going to buy another. It does have its wobbles but it is a TOY, not the real thing!!!! "

    An Incredible Gun....
    By: Alec Hinchcliff

    "I couln't believe how powerful it was! I ordered it as my first AEG to play with my friends, and when I got it, I was also surprised to see that the bettery was already fully charged and ready for use! If you are looking for power, you want to but this gun! To show how powerful it was, after I took it out to play my first game with it, my friends refused to play with me! They said it was to strong and they didnt want to get hurt!! Again I was very impressed by the strength and accuracy of this weapon."

    This Gun Is Amazing
    By: Conor Demmons

    "This gun is awsome. It about 430 fps with .2s but i wouldnt use them because they float up a lot. So i use .25s and its more accurate but decreases the fps to about 400. The crane stock battery cover tho does break easily. This gun is sturdy (other than crane stock). If u buy extra mags some mags do not fit all the way into M4 unless u slam hard into gun. Overall i give this gun 5 stars. "

    I own this gun
    By: Macpon88

    " this gun is great, it hits hard and the rate of fire is very good. The accuracy is 4 out of five stars The weight is nice. Not to heavy and well balanced. The battery is in the butt stock and with a little practice very easy to take in and out. this gun looks awesome. If it werent for the orange tip its be hard to tell its not real.the black paint on the metal gets scratched pretty easily so be careful with that. The rail is full metal it does shift the tiniest bit but it isnt really noticeable and to me isnt a problem its a toy anyway not the real thing. I love the hop up on this not only is is kinda fun to get open( you cock the gun) buts its very easy to use even on the go i constantly adjust it while playing its just that easy. Overall its my favorite gun out of my ak aug g36c. My other guns all eventually have problems that hold up our games weither small or big...not this guy. Hes mr realiable i havnt had a problem with it yet after 5 months"

    Very Nice Gun!!!
    By: Ryan  Richards

    "Very nice gun! Accurate from 30 yards and still accurate around 40... after 45 it begins to hop slightly from stock, that can be adjusted. Easy to install battery! :-) First game with it was awesome! I recommend with 5000 Round Drum MAG!"

    "When I got it, I saw that the box was a little beat up....But it wasnt that bad. My gun work perfectly.. but there is a slight problem. You can't use .20 bbs that well.. They always curve. It's not the hop-up. cause if you turn it too much, it will jam.. Keep it at normal and use .25 or .30 bbs. I recommend the .30. And DON'T use sporting goods bbs. They will break from the hammer. This is BAD for your gun. They work sometimes but just to be safe, use .25 or .30 bbs."

    to the guy below me
    By: anonymous

    "The gun comes with a 8.4v, 1500mah standard stock battery. This gun is a killer deal for the money, i could only find maybe one or two guns that compare to this in power and price.. ive used it in one war so far and it served me well with two kills and 1 death and i suck so thats saying something. pros: good fps good wieght metal rail system durable compact cons: the only problem i have is the rate of fire, its not as good as i wanted for cqb (but then again it comes with an 8.4 volt battery), only about 10 rps but i solved that with a 9.6v battery. tips: get some gun lubricant spray and spray the battery really well so you dont break the battery trying to get it out. and one more thing, if you want to add range mess with the hop up it will make your purchase even more worth it. I put the hopup up a little and it literally added about 75 ft to the range. "

    JG cqb - F6624
    By: Bayou Region Guy

    "Airsoft in Louisiana is a new sport and I was really in want of a good assault rifle with full auto and a retractable butt stock. Found this rifle, fit my needs, and so I purchased. -- Fast forward 4 days, MAN do they ship stuff fast, and I got it in. Opened it, charged battery, and took it out in the backyard to do some target practice. The accuracy and power really shocked me!! This is my first AEG and definitely not my last. From what I can tell as a beginner, the quality of the construction is really good (I do quality control for a rather large electronics company so I know a thing or two about quality), the power and accuracy, like I stated above, is really GREAT. And on top of that, it was about $100 cheaper than some other brand of it, even though the other one was less powerful (how does that even make sense, money wise?) All in all a great rifle..."

    Amazing Gun
    By: Bubba Smith

    "Wow, this is an amazing gun. I have owned mine for some time now and have had no issues with it. It is powerful, accurate, cool as all heck, and overall is beast. The only problem with it is the forward assist, bolt release, mag release, etc. are all plastic. That makes sense though, because the gun is NOT a full metal blow back. It comes with a 1500 9.6 volt stock battery. I have mine chronographed, and it shot 400 fps and 14 rounds a second. The upper, and lower receivers are polymer, but don't freak out, it is good polymer. Besides, you have to pay an extra $100-$250 for full metal blow back. The stock stinks, it is just a basic crane stock with battery storage, and it isn't all that nice. I would replace it. Overall, for a high quality but low budget ready-to-go-out-of-the-box kind of gun i would give this four out of five stars. This is an excellent buy!"

    "I bought the M4 over a month ago and have played several times with it since. It has held up great. The accuracy of the gun is good using the .20 but light wind will make them travel off site. The battery was tough to get in but using some silicone spray helps. I did have it chronographed and out of the box with the battery fully charged it shot consistantly at 400 fps. It's a great gun overall."

    Great Gun
    By: Chace Phillips

    "This gun is great, very very powerful and also very accurate. The rate of fire is definitely satisfying and so is the realistic weight of the gun. The full RIS systems are very rewarding and offer a wide variation of attachment options. The only things that i dont like is that the gun rattles a tiny bit, and the battery is hard to work with, but other than that, the gun is a very good gun and is definitely worth the money."

    overall great gun
    By: a buyer

    "Ok first of all its a good gun, no problems so far other then theres a little pin type thing in the cocking handle that exposes the hop up and it fell out for me, but its not a big deal anyway. It took 2 weeks to ship but when it got here it was worth it. The entire gun wobles alot but wouldnt/doesnt feel like its falling apart. The stock has 5 or so firm positions, and a comfortable rubber butt plate. It has no logos but since its a cheap gun thats what you get. The selector switch on it has a very positive click on it which is nice in nighttime wars. It is also compact but accurate, i can hit a slim flag pole 2/3 shots at 70+ feet away but it gets a little scattered at 110ish feet. It has full RIS for grips, nade launchers, lights and scopes but remember that the front sight on this gun is non movable so youll have a little more trouble buying a scope as to a flip down sight which is "movable" so you can use anything. Great starter gun too. "

    pretty good
    By: Austin Forker

    "Pretty good gun for the money good rof and decent accuracy after hop up and sights are adjusted. would suggest a red dot and extra mags. battery is fine hasnt died during a battle but come somewhat close. About 420 fps out of the box and settles down to about 410 after a couple months. use .23s or so. scratches kind of easily but i am not always careful either. dropped it from 5 feet and nothing happened except a scrath on the grip. Good weight about 10ish pounds. Everything is a little wobbly but not to bad. Its jsut what you get with a jg gun. Sorry about all the typos i am in a rush. Hope this helps guys!"

The only recommendation I would make is to replace the stock battery with a 9.6 small type 1600 mah butterfly battery. As always also purchase a smart charger if you don't have one! THIS GUN IS SICK!!!!"

    "This is a very nice gun. On a scale of 1-10 10 being the highest I'd give its accuracy-81/2, range-8, power-7, ROF-9. The gun is all metal, the scroll thing is on the mag and it comes with a wind-up piece that does it faster than the scrolling. I recomend buying a can of alluminum rds. 'cause at point-blank range it can go about 1/4-1/2 in. into the body. It's just a solid gun period, I realy haven't found anything noticably bad about this gun. And airsoftmegastore was solid when it come to service."

    By: Airsoft guy

    "This gun is a good deal. But you get what you pay for. I've had it for about a month and it's very unreliable. First, the battery gets stuck and theres no were to pull it out except for the wires...which of course rips them. I GOT 1 USE OUT OF MY BATTERY BECAUSE OF THIS so now i have to buy a new one. Also my battery started leaking battery fluid after 3 weeks of having it. And after having it for 4 weeks, while using my vertical grip, I heard a SNAP and now my front sights become wobbly with the slightest amount of sideways pressure on the vertical grip. ADDITIONALY, the piece that houses the fuse often becomes loose and I've lost 3 fuses because of it. Overall a good gun, but it breaks A LOT. Pros: Good Deal Good Fps A lot of metal Cons: Breaks a lot Cheaply made A lot of loose screws that you have to hunt down and tighten when you first get it."

    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
