Introducing A.M.A. (Airsoft Megastore Armory) AEGs:
Airsoft Megastore Armory AEGs are designed from the bottom up with one goal, to provide airsoft players with the most realistic and fully upgraded premium performance AEGs for the best price. We feel that we have succeeded in our mission with our line of full metal electric blowback, factory upgraded, and MOSFET enhanced AEGs.

Our Airsoft Megastore Armory AEGs are a step above other AEGs on the market, providing a high degree of realism combined with superior accuracy, power, and range. We take such pride in our Airsoft Megastore Armory AEGs, that we have emblazoned the A.M.A. logo on each lower receiver. Each A.M.A. AEG is thoroughly inspected and tested to ensure the highest level of performance. Welcome to the Airsoft Megastore Armory, where serious airsoft players load up. Your weapon is waiting!

Performance Guarantee:

All Airsoft Megastore Armory AEGs are built to outperform and outlast the competition, which is why we cover our entire line of A.M.A. AEGs with an industry leading 60 day limited warranty. Our warranty covers your AEG for twice as long as most “premium” brand airsoft manufacturers, because we know our guns are built to last. Ten to thirty days is never truly enough time to really field an airsoft rifle and ensure that it is problem free, which is why our extended 60 day limited warranty is designed to provide you with ample time to test our AEGs’ quality and performance. At the Airsoft Megastore Armory, our first priority is your satisfaction!


The AMR-4 RIS is the railed version of the standard M4A1 platform, featuring a rugged full metal hand guard rail system providing plenty of space for attaching a variety of tactical accessories.  With a sleek modern design and internal modifications and upgrades, the AMR-4 RIS truly stands out in the crowd of other railed M4 AEGs. Featuring a rugged full metal body for an authentic feel, and a powerful electric blowback system, this AMR-4 RIS is one of the most realistic M4 AEGs on the market!

Battle Ready Exterior:
From the barrel to the buffer tube, the AMR-4 RIS is built from solid and extremely durable metal with a full metal railed hand guard, and a nylon polymer motor grip and stock. We have included a functional locking charging handle to provide quick and easy access to the hop up unit, and a functional bolt release that slams the mock bolt home when pressed. The rugged lower receiver features the exclusive A.M.A. logo as well as an individualized serial number.  One of the more intuitive features of the AMR-4 RIS is its large railed hand guard, which provides plenty of space for storing most NiMH and LiPO nunchuck style batteries, making it easier than ever to swap batteries while on the field.  With a full rail interface system, the customizable opportunities are endless, and allows you to easily swap out different equipment for all types of scenarios.  The full metal chopped rear sight is fully adjustable for windage and elevation, and is also removable, exposing a long optics rail on top of the full metal upper receiver. Unlike standard railed M4 AEGs, the AMR-4 RIS features an ergonomic textured motor grip and a contoured trigger guard to relieve hand fatigue. The six position retractable nylon polymer stock is also ergonomically designed, with a rubber butt pad and larger cheek rest. It also features a small lower compartment for storing extra accessory batteries, and a bottom sling swivel. The overall external construction of this Airsoft Megastore Armory AMR-4 RIS AEG rivals top of the line AEGs, but with an exclusive and unique look that is sure to turn heads!

Revolutionary Upgraded Internals:

We have taken one of the best electric blowback Version 2 gearboxes on the market and further enhanced it by adding top of the line internal components as well as low resistance silver core wiring and an enhanced MOSFET! A MOSFET wired AEG for under $250.00 is virtually unheard of in the airsoft world, let alone an upgraded electric blowback full metal AEG! The Version 2 electric blowback gearbox features 7mm metal bearings, a bearing spring guide, a bearing piston head, a full metal air nozzle, and a powerful M120 spring! To enhance the range and accuracy of the AMR-4 RIS, we also included a 6.03 stainless steel tight bore inner barrel, giving it pinpoint accuracy and making it easily capable of hitting targets at 150 feet! The electric blowback feature of the AMR-4 RIS is crisp and loud, and provides a small but noticeable amount of recoil which adds to the realistic feel and performance of this AEG. No other stock AEG on the market comes with all of these features and upgrades installed and ready to go right out of the box! The AMR-4 RIS truly is one of the most advanced AEGs available on the market, and priced well below most “premium” airsoft guns.

Incredible Value:
At Airsoft Megastore, we are committed to bringing you the best products on the market for the lowest possible price, which is why we developed our Airsoft Megastore Armory line of AEGs. Our A.M.A. AEGs built for high octane performance with an upgraded electric blowback gearbox, a factory installed MOSFET, a tight bore barrel, and full metal construction, and priced well below other “premium” AEGs. Not only do our AEGs have more out of the box upgrades and features than most “premium” brand AEGs, they also feature an industry leading 60 day limited warranty!

Battery Charger Recommendation:  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 Airsoft Megastore Armory Metal AMR-4 RIS EBB AEG w/ MOSFET - FOLIAGE *****
Best gun I've ever seen, or owned.

"By far, this is the best AEG you can get for your money. Pros -Incredibly durable body, made EXTREMELY well -Tons of rails -Crazy High RoF (I use a 9.6v) -Great fps -Accuracy is beyond real. The 6.03 really shows, my iron sights are perfect and the bb literally flys perfectly straight with .2g's. All you need to adjust is hop up. -EBB is nice, and the gun is pretty loud from it. -Stock is very easy to adjust. -The battery is a breeze to put in compared to those that use crane stocks. It goes in the rails, and nunchuck batteries fit best with plenty of room and no overly bending wires. Great design. -Mag fits in really well -MOSFET-enough said Cons -You're going to have to restrain your yourself, otherwise you'll end up buying 5. Compared to the G&G Raider XL which I also have that was the same price, this is a much better value by far. Everything the G&G does this gun does better. "

5 Airsoft Megastore Armory Metal AMR-4 RIS EBB AEG w/ MOSFET - FOLIAGE *****
Love it!

"This is one of my favorite guns. I love the M4 styles, granted it's really over used and not as uniqe as a G36 or something. This gun is UNIQE! slap on a NcStar Precision-Grade Compact Bipod w/ 3 Mount Adapters, VISM 7-Intensity Adjustable Red Dot Scope w/ Integrated Green Laser & Flashlight, Airsoft Megastore Armory CQB Assassin Series Aluminum Mock Suppressor / Barrel Extension - 190mm. This gun will stand out! I absolutely dominate with it. The range is incredible for the FPS it runs. The EBB system runs a bit froggy, the full auto likes to feed 2 BB's some times. The Semi-auto runs great (thats what i use anyway so i dont really care). Definately rec- 9.6v Nun-Chuck runs fast and lasts all day. I definately rec this gun to anyone looking for a great M4 that they would like to make their own and customize to their likeing."

Primary weapon

"This gun is just absolutely fantastic, I'm leaving a quick review, I just want to go through the pros and cons very quickly. PROS: Full metal construction (except for the grip and stock), high rate of fire, long distance, powerful, loud, great fps, and it is durable and fun to use CONS: Can't figure out how to remove flash hider without ruining the thread yet, a little too powerful for .20g (they aren't extremely accurate with this gun), and the most important aspect of this gun that I had to get in order to find out was that it does NOT have a powerful recoil! it is weak and almost unnoticeable. Well also, this isn't a pro or con, but you MUST have nun-chuck batteries for this gun. normal batteries do NOT fit in, you have to buy the nun-chuck battery separately or buy a peq box. This gun is amazing and I would absolutely recommend it for anyone who wants an amazing gun for a low price."

Very Good

"I just got this gun and its proven to be very good. Pro Battery is easy to fit (barrel) Super accurate up to 100-150 feet (the tight bore really shows Its a much darker green makes a loud noise ROF is good with the 8.4 nun-chuck Fps is good but not incredible Con Cant find any yet we will find out sooner or later My recommendation is if your willing to spend this much check out other guns like G&G. But this gun is absolutely worth the money and I would recomend it"

4 Airsoft Megastore Armory Metal AMR-4 RIS EBB AEG w/ MOSFET - FOLIAGE *****
Great Gun.

"I have had this gun for almost a year now and It has preformed outstandingly. The only reason I am giving it four stars is because the blow back system no longer works for some reason. This however does not effect the performance of the gun and it does not bother me to much. Pro- Full metal body which makes the gun extremely durable. 6.03 Tight bor barrel makes the gun very accurate. 360-80 FPS makes the gun both field and arena worthy. Battery is the easiest to fit in. Better than any other gun. Li-po ready, makes the gun shoot at a high rate of fire. Lots of rail space for accessories. Con- Mag well is to large making the mag wobble a bit. My blow back function has stopped working. The stock is a bit wobbly, nothing to bad though."

1 Airsoft Megastore Armory Metal AMR-4 RIS EBB AEG w/ MOSFET - FOLIAGE *****

"Ok, bought this gun after ALOT of research and thought this was the best bang for the buck. Man was I wrong. Yes it is metal and yes it has a high fps rate and yes it seems like the best thing to get, but thats is about all it is. The accuracy...well...doesn't really exist, it is that bad. The high fps makes every shot go in all different directions (even with .28s). The hop up is ok but really took forever to get tuned in to an acceptable shot. The magazine wobbles and wont feed properly so you have to basically shove the mag into the gun while you shoot (whats the point?). WORST PART-- the wires wore out the first time i went to the field. Went to my local shop and they said it could not be repaired. WHAT?! I just bought the thing, used it one day, and its broken?! Turns out, this is a javelin knock off and javelin guns can only use javelin replacement parts. Well it turns out javelin isnt in the business of making replacement parts. My gun is useless now. The gun was decent when it worked, problem is that it isnt even close to being any bit upgradable and when it does break, it cant be fixed, and if it cant be fixed, it wont work, and if it doesnt work, then it is pointelss."

I love the pro gunbuilder by golden eagle!
The gunbuilder was very useful and made it easy for me to buy my first mid/high spec gun for just about $300. It gave me comfort in that i can get more parts to switch out at a later time if i wish to change anything about my rifle and that there will be compatible parts for any modifications i choose to do on it. The gun came in full working order and the hopup was even adjusted to be perfect right out of the box. I could easily hit targets over 150ft away constantly. Johnmstopka, USA
