Our take:  It’s been a long wait for the A&K MK43 Full Metal AEG, but we’re glad to inform you that it was well worth it.  The A&K MK43 is the latest and greatest from A&K, the originators of the M249-series, and with it comes a history of excellence.  This variant is one of the most famous military squad automatic weapons in recent history.

The A&K MK43 offers a lot of unique and down-right cool features at a reasonable cost.  Our favorite is hands down the adjustable ROF (rate of fire) switch located underneath the barrel.  With a twist of this switch, you are able to actually INCREASE or DECREASE the rate of fire of this rifle to best fit your shooting needs.  Adjusting this switch accordingly produces a varying rate of fire, from 11-20 RPS (rounds per second).  It’s an extremely useful and neat feature by all accounts, and is STANDARD on the A&K MK43.

As it so happens, rate of fire is one of the MK43’s most outstanding attributes, as it tops out shooting over 1,100 rounds per minute on fully automatic mode!

An adjustable length/retractable bipod also comes integrated onto the gun itself, as users will find it very useful in times of varying Airsoft combat scenarios.  There is also a vertical fore-grip hand guard at the front of the rifle that is every bit as unique as it is functional.  Overall length of the rifle has been shortened from the original M60 to provide superior maneuverability and improve overall balance.

The drum magazine holds a whopping 3,500 rounds of BBs, so you can pick off your opponents all-day-long.

- Full metal construction/full metal receiver
- Full metal gearbox
- A&K’s newest ultra high-torque motor for high rate of fire and smooth firing
- Full metal barrel
- Automatic winding 3,500 round drum magazine
- Full metal adjustable/retractable bipod
- Excellent support gunner AEG machine gun
- High quality A&K product
- Extremely durable

Operation:  Electric Automatic
Build:  Metal gearbox, outer barrel, receiver, stock, bipod/ Polymer Handguard & Grip
Firing Modes:  Full-automatic w/ functional safety
Muzzle Velocity:  380-410 FPS (w/ 0.20g BBs)
Magazine:  3,500rd High Capacity Electric Winding Drum Magazine
Gearbox:  Full Metal SAW Type Gearbox (Compatible with most Version 2/3 internal parts)
Battery Type:  9.6V Mini Battery
Inner Barrel Length:  450mm
Hop-Up:  Adjustable
Weight:  14.75lbs
Overall Length:  37.5” in.
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: MK43 Full Metal AEG, 3,500rd drum mag & mag cover, 9.6v battery, standard wall charger

*There is no semi-auto mode

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.

Gonna get SOME!!

"The particular MK 43 gun I bought was from AM's new Certified Pre-Owned section. I also like that when you buy a CPO weapon you know that it is going to work right out of the box with a warranty. I used one of these when I was in the Teams, and it is a little lighter, and not as detailed, but from a distance it is quite the "looker". Once the bb's start flying you want to tell the others on the receiving end of this bad boy "Sucks for YOU!!" The magazine feed tube installation is not as bad as it seems, to put it on it took me about a minute. Overall, the gun is well built and worth the $289.00 (or full price for that matter)that I paid for it in the CPO section of AM. Now I am just waiting for the next airsoft war with the boys and cannot wait to hear, "We are gonna DIE!!" from them. Like I said, the gun is worth the cost and the build is great, the weight - that is to be expected, the "Holy Crap" intimidation factor - Priceless. Man, this brings back the memories. GO NAVY!!"

A&K Airsoft Full Metal Mk43 AEG Squad Automatic Rifle


I would like to start of by saying that the gun is heavy, for those of you who don't play a support role in Milsim, or just don't use Lmgs this will take some getting used to. If you use heavy guns such as Lmgs you will love this gun. It is Light for its weapon class and comes with bipod and fore grip standard. Many people who own this gun say it can carry 5000 rounds in the magazine it comes with. As much as I want to say god things about the gun I cant say it carries 5000 rounds. It will carry the 3500 that the website has posted. This website was the only website at the time I ordered it to have the gun in stock and they shipped it to me in 4 days. But enough about shipping. The gun is almost full metal but the fore grip and pistol grip are polymer and are comfortable to hold. This cuts down on the weigh significantly. The iron sights on the gun flip up and down, and can be adjusted for distance. The iron sights are however bulky and not very fun to use. I recommend fixing a rail to the cover and mounting a holographic sight on the gun. The rest of the gun is mainly rounded and doesn't offer up any room to put rail space on. The magazine is fairly difficult to attach. Two straps, (one of which doesn't come off) must go on a hanger and a feeding tube must be hooked to a receiver and then you are good to go. But before you can do that you need to take the actual magazine out of the compartment and turn it on. There are three modes, off, auto and continuum. Auto continuously winds up the magazine, (the magazine is electrically wound) and doesn't stop until the battery is completely dead or the mode is turned off. Continuum on the other hand only winds the magazine when you pull the trigger. This mode is much more effective in multiple ways rather than Auto. The rate of fire or ROF, is adjustable. You just simply turn the crank under the barrel and it will go faster or slower. If you don't like the feature or just don't simply want to bother adjusting it you can remove the barrel and install a mosfet chip and it will override the system and give it a constant high ROF without the need to adjust it. Now on to the FPS. This gun was clocking in at 430-440 Fps. If you are playing at a 400 Fps and under limit field this is a MASSIVE con. You will need to use up the spring inside to bring down the FPS. I would like to end my review here because it is getting late and I believe I covered everything about the gun. It is fun to use against people who don't care if the FPS is above 400. It is the best replica of the navy seal model MK43 M60 for the money. It is The best M60E4 replica on the market for the best price. If you enjoy support gunner roles in Milsim, I recommend buying this gun. If you want a Light Machine Gun without breaking the bank, I would Recommend this gun. And if you have common sense and understand logic with the proportions that of a human being that understands logic with the proportions of a smart human being, I would recommend buying this gun. Thank you for reading.




We are very glad to hear that you are happy with the product! This AEG is definitely for players who prefer the support role and it will go through bbs FAST! We recommend using the .25g Goldenball ProSlick Airsoft BB ammo, they will give you a great balance of both shooting range and accuracy.

If looks could kill

"This is one of my favorite airsoft guns. Not only does it look super authentic, it shoots amazing too. It is on the heavy side and I recommend a good quality machine gunners sling. Also a very big battery is recommended so the fun doesn't have to stop. I recommend taping the switch on the box so it cant get jostled and moved during battle. Its a real bear to try and fix in the field especially under fire. Also when removing the barrel its recommended to remove the mag from the gun as discharge all the BBs as it can cause problems reinstalling the barrel if you don't. I have seen spare mags sell for less than $40.00 here and that's awesome. I plan to get a spare some day just in case. The gun fires really good right out of the box so I wouldn't do anything until it breaks, its that good. Everyone loves the look of this gun and I do to. There are many like it, but this one is mine."

"this here is one awesome gun i shot it about 55 yards and it still hit my target not meant for up close shots like it says every thing but the back of the stock and places where your hands go every thing else is full metal could not have gotten a better gun but this gun is not meant for someone small my friend couldn't shoot it with out using the bipod and you might want to look into getting a 10.6 battery that way it will shoot harder fast and longer"

Amazing..... Just simply amazing

"Have had the gun now for about a month and have no complaints about it. At first when I opened it up to test everything I freaked out because it would barely shoot. forgot that I had an adjustable ROF on it so I cranked it up and a lazer of bb's. When I chronoed it, it didn't shoot at 410 like the description says it would.... No, this beast shot at 450! Took it to a game and I was well over the limits of what they would allow so I had to change the spring, no big deal. Gear box is easy to get to and changing the spring is as easy as a flip of a switch. I really don't have any con's to the gun itself. It's an amazing supressive fire weapon and at the same time you can fire it from the shoulder and press through an area with a great amount of fire volume. If you're one of the weaker ones who think an m4 is a heavy weapon, this isn't for you. If you can man up and actually tame a beast though, this is the gun for you! My only complaint is that the screw that connects the box mag to the weapon itself pops off if you don't secure it properly. For this i used teflon tape and just keep the mag connected at all times. Did that on the first day I got it, since then I haven't had a problem at all."

"I got this gun last year and am impressed. The rate of fire is extraordinary and it is accurate (i use .20 gram golden ball pro slicks). It his hard enough to cause an opponent to surrender after a few hits (my group plays until they either run out of ammo). My only issue has been that the mag jams so i would carry a good secondary to defend yourself until you unjam it. Unless the magazine jams you can control the flow of the fight with this gun. I wouldn't purchase a secondary mag because its easier to just dump a bag of bb's into the old mag than it is to attach a new one. Buy an extra battery and plenty of ammo and this can't be beat."

"This gun looks so cool. I watched a review on it. It shoots 380 fps-400 fps. Theres a knob on the front of the gun (if you own this gun and havent figured this out you should listen to this) Ok turn the knob while firing and you will notice that the rof goes up. It can shoot from 6 BBs a second all the way to 20 BBs A SECOND!! Thats awsome! Great gun A must Buy! "

very dependable and has an excellent rate of fre

"purchased this gun about a year ago. we needed a support gun for our airsoft team.let me tell you it doesn't disapoint the rate of fire is outstanding upgraded to a red madbull bucking and had a custom built 5400 11.1 volt lipo battery the range and rate of fire is crazy. I shoot a lot 10000 rds per game every other weekend only had to replace four or five buckings and had to replace the box mag."Finally wore out" well worth the money for that massive fire power your team needs.. warning cry babies will say gun is hot, its not 394fps with .20s its just the rate of fire "

creates art

"this is by far the best oreder i've ever made on Megastore. It doesn't shoot as powerful as my AK-47 or M109 but the ROF more than makes up for that! If you use it in an Airsoft War (which i will on Halloween), i'd recommend having an extra guy or 2 with ya. When u move your gonna need covering fire and your gonna need help reloading and shooting. I'd recommend someone with a good gun and can act fast to CQB encounter"

Great gun

"This is a great gun i just got it and even without a good charge it has a great ROF and range the mag capacity is great and will last you a while with 1 fill i would suggest that you keep some bbs with you when you play cuz if you run out its easier to refill the box mag than to change it. if you have the money and you want an LMG this is your gun. its about 18 pounds with ammo in it and is really sturdy.also i live in hawaii and the shipping was only 5 days as opposed to a week or 2 from other websites... bottom line. BUY THIS GUN!!!"

Great Gun

"Got it last week pulled it out the box chrono 421 a bit hot for where I was. Made a nub out of bic pen for the hop up It is just a smidge longer than the original works great. Going to look in to using a piece of auto vacume hose so not as hard on bucking should do the trick. Two screws in the box don't have a clue where they go, one screw missing from side and not either extra screws fit. Chews thru batteries but what ya expect from a stock battery."

Its a reaper

"Though this weapon goes against my covert tactics, its incredible firepower allow it to slide. If your looking for heavy weaponry then here you are. Only difficulty I had was a split wire which was a quick fix. The packaging on it was a brown mailing box and styrofoam bracing...pathetic for the price...aside from that...its a reaper. Nuff said. I am currently ordering an M702 revolver and shall add my take on that as well. "

A Truly Awesome Weapon

"The charging handle assembly design is no good. Mine fell off right out of the box, got it welded, and it still fell off even with the extra pressure holding it together! I've heard about this same problem happening to other people as well. Luckily, this part isn't necessary for any kind of function. Concerning the magazine, it works great for the most part. From time to time it will misfeed but is generally very reliable and you never need to wind like a true support weapon should be. It has three settings: "ON" which will give you the constant helicopter-like noise one of the other reviewers described. There is also "CONTINUUM" which will self-wind the mag every time a round is fired off. Definitely one of the best parts of the gun. There is also "OFF" which I'm hoping is pretty self-explanatory. Performance is fantastic. It's not extremely hard-hitting, but it doesn't necessarily need to be. It shoots extremely fast and your opponents will definitely be calling their hits."

it's definitely cool

"First off i got this AEG and loved the look about it. Read the book and then plugged in the battery, Right off the autowinding box winds up and then starts to sound like a helicopter. So i pull the box mag wire off and tried to figure out how to adjust the winding, so after i finally pulled the box out of the canvas i found the switch, with no help from the manual. Secondly, the Hop up doesn't work and it only fired at 285 for FPS. Luckily the spring is easily swapped out. All in all i love this but expected a little more out of a 300+ dollar gun.. "

so so

"This was an excellent gun while it worked. However after about 6 months of use it began to give me problem. I had to repair the wiring harness. This fix was short lived. After that the microswitch for the trigger failed and has to be replaced. Also the air nozzle at the front of the gearbox is made of plastic and it is broken and has to be replaced....All of this would not have been such a huge deal if the gun were not such a bear to take apart and put back together. Not a good choice if you are not really good at gun repair and maintenance."

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
