Our take:  The NEW A&K Full Metal M4 RIS Carbine AEG is part of A&K's new line of completely redesigned, performance oriented, metal body AEGs. These NEW A&K AEGs are built to the same performance standards as other top tier airsoft guns costing nearly twice as much.  These A&K AEGs not only feature top of the line performance in a durable metal body, but also include everything you will need to start using the rifle! The A&K M4 RIS Carbine includes an 8.4V crane stock battery, a standard wall charger, a 300rd high capacity metal magazine, two rail covers, and a vertical fore grip, and a metal replacement flash hider! The M4 RIS Carbine AEG packs a huge punch in a maneuverable and compact size, shooting consistently over 400 FPS! The tactical M4 RIS Carbine AEG is built to perform and endure in the most strenuous airsoft conditions!

The M4 RIS Carbine features a fully adjustable crane stock, which provides comfortable cheek support and makes this AEG well adapted for close quarters combat. This M4 RIS Carbine AEG can also easily hold its own in an outdoor environment. With a precision inner barrel and fully adjustable hop-up, it can easily hit targets beyond 150 feet! The M4 RIS Carbine AEG features a full metal upper and lower receiver, a full metal outer barrel, full metal front and rear iron sights, and full metal sturdy rail system  — which lets you attach rail-mounted accessories like a tactical rifle laser unit. The only plastic components on the rifle are the retractable crane stock, the carrying handle, and the motor grip. The A&K M4 RIS Carbine's construction is extremely durable, and has a realistic weight and feel.

The new A&K Full Metal Body M4 RIS Carbine has a redesigned and reinforced metal gearbox with a factory installed M120 spring, making it one of the hardest hitting stock, metal body AEGs on the market! The full metal gearbox features metal bushings, a metal ball bearing spring guide, a full steel gear set, a high torque motor, and a perfectly sealed cylinder. The A&K M4 RIS Carbine also features a full metal hop-up unit as well as a 6.04mm precision inner barrel, providing excellent range and accuracy. The M4 RIS Carbine can easily hit targets at over 150 feet away!  

Overall, the A&K Full Metal M4 RIS Carbine AEG is one of the best metal body M4's on the market, under $250. With solidly constructed full metal externals and a reinforced high performance gearbox, this AEG is able to hold its own against some of its top tier AEG competitors. The A&K M4 RIS Carbine AEG provides great accuracy and hard hitting power in a compact size. If you are looking for a top performing full metal AEG, but can't afford the top tier price tag this is definitely the AEG for you!

- Metal body (full metal upper & lower receiver)
- High performance/ High Torque full metal gearbox and motor
- 300rd Metal high capacity magazine included
- Realistic weight and feel
- Full Metal Rail System for mounting optics (rail-mounted red dot scopes) and accessories

Muzzle velocity:  400+FPS with 0.20g BBs
Rate of fire:  11 RPS (Rounds per Second) with an 8.4v battery

Package includes:  A&K M4 RIS Carbine, 300rd metal hi-cap magazine, 8.4v 1500mah crane stock battery, standard wall charger, and cleaning rod

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.

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.

5 440 FPS A&K Full Metal Airsoft M4 RIS Carbine AEG - Full Metal Gearbox *****

"This gun is absolutely incredible for the price! This gun shoots very far and very fast. It is a bit heavy, maybe 5 pounds. But it only makes the gun even more awesome! This gun is exactly how the website lists it. It is full metal, except for the stock I think is heavy plastic. I have had it for a while now, has not jammed once. This gun is just fantastic. People who say this gun is horrible are lame. Overall this gun is just great for any use! PROS: *High Cap Mag, bb's don't make lots of sound inside the mag *Full Metal *Shoots Fast *Shoots Far *Has not jammed once * There are no cons about this gun!"

Fantastic gun!

"I love this m4. I wanted to wait a year after buying this to write the review. It has been a little over a year. The gun is great. I have shot over 200,000 rounds thru it. I am just now thinking about replacing the bucking. Usually they wear out so fast. The gun is solid and well built. It has never had a problem. It shot 410 out of the box with .20. I would recommend getting a 9.6 battery for it to help your rate of fire. Like other people said the only things that are plastic are the handle and the crane. And cranes are always plastic. It comes with a tight bore, a 120 spring and a high tourqe motor. I would definently recommend this gun. It's on sale for $167 so yes,I just ordered another one as a back up/loner. Good luck!"

Great gun

"So, I got this gun for a few reasons: I wanted a comfortable gun, something less bulky then my AK47, and high fps. All of which I was satisfied with. When they said this gun shoots over 400fps out of the box, I wasn't entirely convinced. So I decided to chrono it a few days after it arrived, and it was shooting at 415. That's pretty darn good right out of the box. Its especially good for a decent priced M4. Okay, so like any Airsoft gun, it has some flaws. I found it hard to get the mags in the gun. I really had to shove it in just right or else it just wouldn't really feed BBs. This took a little getting used to, but its not a big deal to me. Overall this gun is comfy, its shooting well over 400fps out of the box, and is relatively lightweight. The range is decent, nothing special. And the mags are a bit tough to get in. I recommend you buy this if you're looking for a good M4. I also really like the crane stalk! Its a nice edition."

Excellent Gun!!!

"This M4 is all around a nice airsoft gun. Shoots a consistent 430 FPS no problem, and is very accurate at short range and long range shots. The battery compartment was a little hard to find but it's in the stock like most M4s. The trick is in the adjustable stock lever. Pull it up to take the stock off instead of pushing it down to adjust the stock. AMS also has a video on YouTube that demonstrates how to do it. This gun was 100% worth every penny and I would recommend this to anyone."

"This gun is amazing the only plastic parts on it is the Stock,Flash Hider the grip and they carrying handle it comes with but you can easily take it of and buy a metal one for 10 bucks like i did it shoots at 440fps with .20 gram bbs and has amazing range its definitely a good buy and you wont regret buying it."

great gun

"I bought this gun from this site no to long ago i have already had it in the field and had no problems all day i let the battary die after i got it out of the box and then charged it for about 4 hours and then it worked all day all of it is metal except the tip and the stock not one bb jammed all day i was hitting from 50+ feet away all day and with no missed shots the battry loads from the stock so it is a little difficult to get in but once it is in just leave it in and take the stock off to charge it is much easyer all and all fantastic gun not a problem yet and does not seem like it will have any"

Tactically Sound

"I bought this rifle because I found that it resembled the M16, and I needed a full metal gun to use outdoors. It shoots well, and once you get the iron sights sighted in (Or scope) it is accurate I'd say to about 150-200 feet. This is a rifle you really want to take the time to sight in folks, its very reliable. I don't see any problems with the battery, you may have to completely remove the stock of the gun to get to the proper compartment, from there its rather self explanatory. Though I will admit, the magazines are rather difficult to get solidly into the chamber. I had to delicately apply duct tape to them so they do not wobble. I will reiterate something another reviewer had said. TIGHTEN ANY VISIBLE SCREWS, YOU DO NOT WANT TO LOSE ANY OF THEM. "

Great gun

"Jake, it says in the description that the battery goes in the crane stock. Also, to anyone that may be wondering, the only things not metal on this gun are the crane stock (the tube is metal) and the M4 carry handle. I was mad about the carry handle but i can get a full metal one cheap enough..."

great gun

"right out of the box this gun was shooting great. i was very happy with the range and the ROF. be aware though, MOST parts are metal. the carrying handle, charging handle and other little pieces are plastic. it is quite a heavy gun, but its an m4-easy to handle. quite accurate, however, it chronoed out at ~370 with .25's. BUT DONT let this turn you away, fps IS NOT everything. and unless you're a dink and enjoy hurting people, you dont need a gun to shoot 440. Also, if it helps anyone, i do woodsball. I play at Federal Fortress, in Monson Ma if any one is intereted. overall i would totally recommend this gun to anyone PS. i bought the 9.6V nunchuck and would defiantly recommend getting that. it really improves the ROF"

the best

"I bought this to replace my old m4. the minute i took it out of the box it felt way better then any other guns i have ever used. it knocked my ak right off of its title as the best gun. the only problems that i found with it were that it doesnt come with any i had to find a video on youtube to figure out how to put the battery in. other than that its the best gun i have had."

Very Good Weapon

"I bought this as my first airsoft gun, and I was not dissapointed. I dont remember getting an instruction manual for battery installation, but I might've just lost it. no problem, i just watched AMS's video on hoe to do it. anyway, the gun feels nice, and with the battery in the stock, the gun is fairly balanced. the mags are hard to load, but all you need is a little force. Very solid. yet to officially chrono it, but the weapon, with sight adjustment, is very accurate. one thing to note, is the gun weighs in at 9.8 pounds, no BBs or battery (but i did have a scope, so that probably offset the weight.) but this means that this gun weighs about the the same, if not MORE than a real M4 Carbine. Very Solid, would reccomend to anyone who likes M4s"

Kicks Ass!

"This is my second AEG, and this weapon totally blew the other one out of the ballpark! Shoots hard and pretty accurate with .20s. I let my brother shoot me with it point blank and it left me a few good welts. (I like to know the type of pain I am inflicting to others;)) Feels very nice and heavy. Only con is the fact that the mags are difficult to get in."

"While it worked, it was quite powerful. My gun was physically impossible to sight in because for some reason the front sight was twisted and it wouldn't twist back. I tried to fix the sight problem by opening up the gun and and rotating the mock gas tube, but after 45 minutes when i finally got the upper receiver off because of the screws being to big for the openings, and the gas tube wasn't the problem. A friend of mine got this same exact "NEW 2012 Production Run Model" in November of 2011. And if you read just above the other reviews, you will see when they were posted and realize that this isn't a 2012 version. The problem that I noticed a few days ago was that the hop up buckling was BS, the gears inside of the "NEW 2012 Production Run Model" gearbox were stock and already stripped. Now I can either go out and buy another 200+ dollar stock airsoft gun or I can spend the same 200+ dollars on new internals. I'm going to record what my gun is sounding like in a little while so i'l post the link to the video on here."

"Bought this gun after reading great descriptions of power and a solid metal body. However, after attempting to fire the gun the bbs would not load into the chamber. The gun fires 2-3 shots before not allowing any more bbs to pass into the barrel. This issue is most likely due to poor construction and parts. If you wish to avoid aggravation and disapointment avoid this gun."

Best in Class Customer Service

Same Day Will Call Pickup

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
