    Our take:  The newest production run JG airsoft M4A1 Carbine is the most advanced and high-performance JG M4A1 EVER manufactured, and is a great and telling sign of what’s to come from JG.  The all-new JG airsoft M4A1 has been re-designed from the ground up to be the more powerful, more accurate, and more reliable than ever before.  It is extremely versatile in that 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 overpowers even Tokyo Marui AEGs and its JG enhanced full metal gearbox, this M4A1 is ready to rock and roll.   Because it is compatible with Tokyo Marui parts and many other aftermarket upgrade parts, it can be easily customized and upgraded.

    -This package includes a Airsoft Megastore Armory Precision 2x42 Red Dot Zooming Sight unit.  This is one of the most sought-after rifle scopes on the market due to the fact that it combines the advantages of a red-dot aiming system with those of a traditional zooming scope.  Airsoft Megastore Armory’s ultra high-quality 2x42 Red Dot zooming scope allows for a helpful 2x optical zoom, while maintaining a 7-intensity adjustable RED DOT at the center of the scope.  That way, you can quickly acquire targets as you would with a standard red dot, but have the extra 2x zoom for more accurate shots/target acquisitions.  

    On the M4, the Airsoft Megastore Armory 2x42 zooming red dot sight works FLAWLESSLY.  Its unlimited eye relief allows for effortless aiming from virtually any distance and/or viewing angle.

    - Airsoft Megastore Armory OpSpec 3-point CQB fast-adjust rifle sling (in black).  Once you dial in the optimum sling position for you and your weapon, you can reap the benefits of lightning-quick engagement from various shooting positions.  Ease of use and adjustable straps allow for users to quickly find the optimum sling and weapon position.  Ultimately, this rifle sling, made out of ultra high-density tactical nylon, allows for the weapon to be milliseconds away from being "at rest" to being "engagement ready."

    The NEWEST production run model, this M4A1 from JG has been re-worked from the ground up to be even MORE powerful, MORE accurate, and MORE durable and rugged.  JG has reinforced the build of the gearbox to withstand higher FPS while maintaining a high rate of fire; the gearbox works harmoniously with the newest version of JG’s ultra high-torque motor to deliver OVER 800 ROUNDS PER MINUTE on full auto at OVER 400 FPS.  The addition of a factory-installed tight bore barrel enhances accuracy greatly, and is perhaps one of the best overall upgrades done to the JG airsoft M4A1 Carbine.  Add the one-piece metal barrel set up to eliminate barrel wobble and you have one of the MOST SOLID airsoft M4A1 AEGs on the market for an unbeatable price.
     THIS AEG SHOOTS AT OVER 420 FPS!  CHRONOGRAPH VERIFIED!  DOMINATE + ANNIHILATE THE AIRSOFT FIELD WITH THIS POWERFUL AEG!  It’s a true sleeper, other players won’t even know what hit ’em!  420+ FPS coming out of a standard-looking airsoft M4A1 is TRUELY amazing.  We could barely believe our eyes when we read the chrono readout!
    This NEWEST JG airsoft M4A1 is part of the best AEG line yet.  Shoots over 400 FPS+ right out of the box with the best accuracy/rate of fire we have seen YET.  Complete ONE-PIECE METAL TIGHT BORE barrel, just like the Tokyo Marui line of M4’s.  Why pay $300+ for a TM when this JG shoots MUCH harder and has the same high-end hardware to match?  [TM:  290 FPS vs.  JG:  400+ FPS]

    New JG M4A1 Carbine Upgrades:
    - Like all Tokyo Marui produced M4/M16 airsoft rifles, this JG airsoft M4A1 now features a tight-bore metal ONE PIECE BARREL for maximum accuracy and performance
    - This AEG is 100% compatible with Tokyo Marui parts
    - Newer Generation 3 metal gearbox comes with an M120 spring pre-installed for maximum power AND more durable metallic-synthetic bushings/gears to HANDLE all that extra power
    - Adjustable hop-up (TM-compatible hop-up unit) and selectable fully automatic/semi automatic firing modes, along with a functional safety mode
    - 385-435 FPS + firing power ensures that you will DOMINATE any airsoft game.  Accuracy and power better than that of TM M4 during comparison testing
    - This newer M4A1 model replaces the older JG M4, offering noticeably better power, accuracy, and quality for a minimal price increase.  Still features a high-capacity 300 round magazine
    - This M4 is extremely versatile and will dominate in any game, be it CQB (close-quarters combat) or outdoors
    - Premium battery and wall charger 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.


    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.

    Operation:  Electric Automatic
    Firing Modes:  Semi-automatic and Full-automatic
    Muzzle Velocity:  385-435 FPS
    Magazine:  300-round high capacity (gear wind-up)
    Gearbox:  Full metal
    Hop-up:  Adjustable
    Weight:  7 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, rechargeable battery, wall charger, instruction manual, unjamming rod, 300-round high capacity magazine, Airsoft Megastore Armory 2x42 Red Dot Scope, Airsoft Megastore Armory three-point CQB rifle sling

    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.

    "Just a hint, when purchasing this gun and want to upgrade to a ris rail system, only the dboys m1 rail system will work for this gun, and plus, you can fit a lipo stick battery in the ail system, so no peq box either. :) great gun though, love the red dot scope and sling that comes with it. if any one wants to now how much metal there is on this gun, first off their is the metal gearbox, the hop up inside is a mix of metal and plastic gears, the crane stock is polymer plastic, and so is the handguard, the hand grip, the foward assiting knob is plastic, and the flash hider are all plastic. but the 300 hi-cap magazine, front sight, rail on top of the gun, red dot scope, fixing ring, carrying handle, and the outer barrel are all metal. This gun is still amazing and its lipo ready too!! great if you want to upgrade in the future. Excellent for its price!!!!"

    Good gun
    By: bdog

    "This gun is very durable despite the fact that it is plastic. The accuracy is very good, as well as the gun being hard hitting. Cons: The front sight does get in the way of the included scope. Do not use cheap ammo though. This will cause the accuracy to be horrible rather than excellent."

    read this it will make u wanna get it!!!!
    By: scott odonoghue

    "im just about to get this gun on the 10th and i've read reviews about this particular weapon and the fps really is 437 the highest i've seen in 12 review! when i get the gun i will do an unboxing video and a shooting test. this gun is defiantly worth the money, the reason why i say that is because my friend have the same exact one just without the assessories and it shoot straight at the 150ft mark on a headshot target the slowly curves. this weapon is some damn worth the money its not even funny, if u want a sniper at the same time as a machine gun then get this. but if u also wanna play cqb take out the m120 spring a change it, then their u are...bye bye"

    "Bought this a couple weeks ago. I have friends with other JG guns and they are all very nice guns for the price. This gun is lighter than the typical full metal setup. It also shoots very fast. The spring could be changed to make it shoot harder but you would lose speed. I think its a perfect balance of power and speed. The scope and sling are great extras. With the speed of this gun, I am tempted to buy an electric feed 5000 round drum and can become a heavy gunner with this gun. Great price for a great gun package. You can not go wrong with this gun."

    This gun
    By: Ryan Horgan

    "First of this was my first aeg. This gun is very good. Accuracy stays pretty good up till 100 feet and every now and than a bb will curve off to the left or right. But not a big deal. Also the stock is a bit wobbly and so it the mag well but it is nothing that effects the performance. It has a decent rate of fire with a 8.4 volt but I recommend a 9.6 for a better rate of fire. The internals are ok but they could have done a better shimming job. But the motor is fine and so is the spring but I would get a better hop up because it doesn't do much but over all one of the best guns for the price and I love it. Great purchase and the 400 fps hurts a ton when you get hit. I highly recommend it."

    "It is a lot better than it looks, it shoots fast and hard, but it doesn't have very good accuracy. The scope isn't very good either but other than that the gun is amazing for the price given. Although it is built poorly there are many loose parts"
