    Our take:  The NEWEST JG FULL METAL M4A1 CARBINE has finally arrived at Airsoft Megastore.  For the first time, EVER, you can get a FULL METAL JG SHOOTING HOT AT OVER 400-450 FPS with no compromises!  We would liken this masterpiece to a KWA M4A1, but feel that the JG M4A1 is more advanced and thus even MORE superior in some ways to the KWA!   The best part is, JG has pre-installed a MOSFET CHIP, and for those who do not know what the MOSFET does, details are below:

    - Performance regulator chip, to ensure all systems are in the green (controls variables like heat and voltage to ensure the highest rate of fire even under the most strenuous conditions)
    - High performance MOSFET aids in power delivery, meaning quicker trigger response and longer battery life
    - Previously available only on CUSTOM airsoft guns costing lots more money, the MOSFET is a standard feature on the all-new JG Full Metal M4A1
    - Lowest price on the market for a MOSFET-equipped airsoft AEG, only at Airsoft Megastore!

    For starters, it features a full metal receiver/body, full metal tightbore barrel, full metal fully reinforced, re-designed advanced M4A1 mechbox, along with totally reworked internals for 400-450 FPS of PURE POWER surging out of a JG with a full metal body.  As always, battery and charger are included.

    Along with improvements made to the gearbox, JG has also made SIGNIFICANT improvements to its ultra-high torque motor design, which is quite CLEARLY REFLECTED in the inclusion of a 9.6V battery, STOCK.  That means that the motor was re-designed to be able to shoot upwards of 900-1000 rounds per minute; the 9.6V battery that comes STOCK with the gun enables it to do so with FLUIDITY and EASE -- never have we seen a more calm and composed airsoft rifle cycling 950-1050 BBs per minute with the STOCK 9.6v battery!

    And if that's not enough, this FULL METAL JG M4A1 also features advanced ULTRA-LOW RESISTANCE wiring throughout the gun, along with an elite stand-alone voltage stabilizer processor-unit (MOSFET) that regulates everything performance-related to ensure that the gun is running at optimum condition (there is a picture of this advanced unit in the product pictures -- look for a fluorescent yellow/green chip-looking device).  It's almost like having a separate processing system to regulate JUST the performance of your airsoft rifle (cool!) -- JG's definitely stepping it up and we're sure ALL the lucky buyers of this new M4A1 will be able to tell first-hand.  

    This is the MOST ADVANCED and MOST ANTICIPATED JG arrival yet.  The JG FULL METAL M4 ...  it's the best we've seen to date and is definitely a step in the right direction.  Blows away the competition (other $300+ Full Metal M4A1s) in side-by-side comparison testing, while STILL offering the best value on the market.

    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, 300-round high capacity magazine

    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.

    FB6604 JG Model M4 M-16 Rifle
    By: Matt Maryan

    "This is by far one of the best shooting, longest lasting M4 I've ever owned. The Mechbox is a Golden Eagle Up-graded gearbox, it's rock solid, trust me, I've taken lots of diff brands apart, this one is great! It has bearings on just about everything you need them on, this gun works flawless every Sat, Wed night. I have the A&K, Dboyz, CYMA, JG is by far a great choice for longevity! It doesn't break! Mine cronyed at 417, 423 always, it hurts like hell, so a player will call his hits. Buy this one, over KWA, CA, Echo 1 save your money! You wont be disapointed! I'm 42, been playing for years. "

    Great gun for price
    By: Gold

    "The gun deserves 5 stars for sure, but a few things to talk about. No no no, it does not shoot 450 fps. I chrono at 335 with .20g. Also the BPS is 12 on a full charge. Yes like the other comments, i agree that the motor does not heat up at all. definetally need to upgrade the hop-up on this gun, but otherwise it is fantastic. And the mosfet only adds to its greatness."

    Amazing gun for decent price
    By: Froslick

    "This gun is amazing! I've had it for about a week, and i love it. The ROF doesn't seem like it is 1000+ bbs per minute, but it it pretty high. After i sighted mine in, i was hitting golfbal size targets at around 90 through 115 feet. the motor does seem to heat up quickly, but other than that, GREAT PURCHASE. it is a good gun to build off of and upgrade on, definalty worth the $220, dont over look this gun while shopping on AMS, its one of the biggest bang for your buck?"

    "mosfet chip increases rof and trigger response, tight-bore barrel, reinforced gearbox, 430 fps w/ .2, 16-17 rps, this has to be the best gun you could ever use on a field, accurate enough to slap a scope on, high enough fps to out range your opponents... i'm not trying to brag but i am a very good player i average at least 4-5 people per game out before i get hit and that's minimum and i have shoot snipers aegs gbbs, good and bad, and this has to be the best all around gun. if you have the money. BUY IT!"

    Punisher Build
    By: Duyane Turner

    "I bought this gun 3 weeks ago and am very impressed with it! The fit, finish and function are flawless! As to the rails, or lack of, go to external upgrades and order a set! I have already added a Madbull AGX grenade launcher to mine with a temporary rail added to the bottom handguard until my RIS set come in. I'm building a replica of the M-4 from "Punisher, Warzone", and for the price, you simply can't beat The Megastores price for what you get! Thanks from a happy customer in Louisiana!"

    Best Gun Ever!!!!!!!!!!!
    By: Buy This Gun!!!!!!!

    "I just got this gun and it is super powerful. Shot it in my pond and killed a fish! Also, it is very acurate. It shoots about 150 Feet! It put holes right through a can at about 35 feet. Make sure you use a high quality brand of bbs or it will jam. Use .20 or higher, up to .28. I use.23. If you play Call Of Duty Black Ops it looks just like the commando and M16. Pros -Far Range: 150 Feet -Extreamly Powerful: 450 FPS -Full Meadel -300 Round Hi-Cap Mag -1000 Rounds A Minute: About 17 Rounds Per Second Cons None At All!!!!!!!! "

    Great gun

    "Yeah this gun is definetly worth the money. It is extremely sturdy, and a good platform for upgrades. It is really accurate so I put a scope on and thought it would be more difficult to aim but I was surprised. The only major problem is that the battery is garbage. it wont last u a full days war or even like for an hour and a half probably without lowering the rate of fire. I just bought a 9.6 volt 2000 mah battery. It is definetly worth the money!!!!!!"

    great gun
    By:  tyler

    "i just received the gun yesterday and i was at the dentist when it came i so my jerk of a brother opened it and charged the battery. when i got home i tackled him. out of the box it looked beautiful. once the battery was charged 5.6 hours i got ready to shoot. i used .2 some came in the box the other 1000 were leftovers from a previous war. it shot so accurate and fast the gun sounds so quiet and fast i was shoot inf a big pin on my dads backhoe about 6 inches and if it wasnt a hit it was like 3 inches away from 100 feet. it was suprisingly heavy but im used to a 3 pound broken peice of crap from dicks sporting goods great gun but the carring handle is a little messed up because i cant take it off with out yanking it off and i cant adjust from the big circle to the precision one. im probably gonna by a red/green dot sight or an acod anyway "

    Great Piece of Equipment
    By: Krypto Kowboy

    "I just received my order and I am super impressed. This gun exceeded my expectations immediately. Once the hop up was adjusted this thing shoots like a champ. Hard and fast, I'd hate to be on the other end of this barrel !!!! One downside, the clip that came with it falls out, the spare clip fits OK, but the clips from my CA M15A4 fit nice and snug, think I'll try some electrical tape on the JG clips to see if it helps."

    yes lipo ready
    By: Matthew Bridges

    "Yes the gun is lipo ready. the Mosfet chip makes sure its lipo ready. However, I dont think it is necessary to get a lipo battery cuz its already shooting a 1000 rounds and min. and with the lipo youre putting more ware and tear to the gears and gear box. I just got my fb6604 and all I can say is OMG!!! This gun exceeds my expectations its truly amazing and very accurate reliable machine. The best buy I have ever done by far!! Recommend getting a tacticle sling either 3 point or two point. It will come in handy cuz it weights 9lbs. doesnt seem much butter running around for a couple of hours; your harms will get sore. Great workout if you ask me lol. Once again I like to thank Airsoft Mega Store for the great deals, prices, support, and premium customer service. "

    This gun is awsome
    By: Terry Thomas

    "i just had a game today with this gun, it holds a really good charge to it, it has a realistic sound to it, very accurate and i had it chrono'd and it goes 440 fps with 20g bbs, the only problem i have with it, is that it dont have a rail on the barrel but thats ok because after this game today i say it dont need anymore attachments to it, it is perfect i think i'll buy another one just like this one"

    2010 JG Full Metal M4A1 Carbine AEG Rifle
    By: Henry

    "This is a great gun to start of with. Pros: Great range, I can snipe someone from almost 300yds! I also got a better battery for it. Long battery life, I have the battery it came with, which last for about 3 hours, and the Tenergy 9.6v 1400mah, maybe 4-5 hours, I bought, I also bought a smart charger which is great and I highly recommend. I haven't chroned it yet but will soon and except at least 425fps based off of others reviews. Cons: Need to have more expensive bbs is more an annoyance but atleast you know it won't jam. Mostly metal, not all metal, but that isn't that big of a deal seeing as JG used some of the highest quality ABS plastic for the 2 or 3 plastice pieces I have ever seen. Overall it is a great gun that has more pros then cons. I would recommend using HIGH QUALITY BBS only, I used some Crosman and my gun jammed in less then 10 shots, I use Javelin .25s now and yet to have problem with them."

    this gun slaps.
    By: Chad Bice

    "just got it today, fired roughly 10 rounds and i'd seen enough. i'll make it brief. PROS: full metal body texturised polymer grips, very solid it's a pretty quiet weapon, unique sound at least 15 rps with 9.6v MAG's midcaps fit perfectly CONS no internal dust cover over the hop up (strange, i like to keep mine open when i play for realism) the paint job it comes with is almost a shiny black, i'm gonna do a quick camo job plastic flash hider"

    Agreeing with the guy below me but still great gun
    By: 8===D lol

    "This gun probably chronos around 370. But most official airsoft playing fields only allow 400 fps on guns. SO.... Anyway, the rate of fire is WICKED and the gun is built like a rock. It also looks identical to my friends AR-15. If i were you, i wouldn't get this gun so I won't have to be on the other end of it. :) OH YEAH: Its also lipo-ready"

    I just got this gun about an hour ago.
    By: Noobie 916

    "Pros: Range - this has better range than most other guns on the battle field. (I upgraded to 9.6 1400 mah. The gun included a 9.6 1100) Rate of fire - Better rate of fire than all the guns I saw on the battlefield. Full Metal - I own a real AR 15 and it isn't 100%, but neither is my real AR 15 so don't complain. It is just like the real one. Cons: FPS - Not 450 - mine was 438 and that was the highest it went. Electric cuts out - simple fix by crimping the wires slightly on the motor Rate of fire and magazine winding - the rate of fire is so fast that you will find yourself winding the magazines a lot. This is more a magazine flaw then gun flaw. Overall: I got a lot of props on the battlefield today with its great range and rate of fire. I got the 5000 round drum added and wished I bought the auto drum. The gun was shipped to me with a few scuffs hence the 4 star rating. Other than that, get this must have M4. "

    "This gun is alright MPEG, though for some reason you cant get into the gear box. Im not sure if its my gun or not but im trying into install a tighbore but i pull the pin and with all my might try to take apart the receiver but its no go. I dont know maybe im missing something. Though thats what the manual says and i still cant get into it. Gun shoots ok, it does not shoot at 450 maybe around 390-410, fires about 800 RMP and for some reason the accurate is crap. This gun would get 4 stars but because you cant get into the gear box im giving it a 3. After all once something breaks how the hell am i going to fix it if i cant get the receivers apart."

    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
