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!

AMR-4 A1:
The AMR-4 A1 is based on the standard M4A1 platform, however it is anything but standard. With modern modifications and internal upgrades, the AMR-4 A1 truly stands out amongst other M4A1 AEGs. Featuring a rugged full metal body for an authentic feel, and a powerful electric blowback system, this AMR-4 A1 is one of the most realistic M4 AEGs on the market!

Battle Ready Exterior:
From the barrel to the buffer tube, the AMR-4 A1 is built from solid and extremely durable metal with a polymer hand guard, motor grip and stock, similar to a standard M4. 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. The full metal carry handle features a fully adjustable rear sight and is removable, exposing a long optics rail on top of the full metal upper receiver. Unlike standard M4 AEGs, the AMR-4 A1 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 A1 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 A1, 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 A1 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 A1 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.

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 Full Metal AMR-4 A1 EBB AEG w/ MOSFET - BLACK *****
Solid Gun, Great Price

"I just ran this gun through a couple of tests, right after receiving it. The gun feels very solid and well built. Several of the metal parts are a bit of a different color than the rest of the body(black). Not sure if it's supposed to be that way, but doesn't detract from the look of the gun. Also, the mag that came with the gun, is foliage colored. Again, not that big a deal, but not sure if it's supposed to be that way. UPDATE- 5/20/12 I used this gun at an all day op yesterday. First, this gun has some amazing range. I was able to hit enemy forces across a ravine about 50 yards away, with no problem. It has an amazing rate of fire with a 9.6v battery. Second, the EBB feature of this gun was awesome, while it worked. The EBB went out after about 1000 rounds. Still, the performance of the gun was flawless, despite the EBB going out. I ended up putting around 2000 rounds of high quality, 20 gram bbs, through this gun. I will be contacting megastore to see if the EBB is covered. "

5 Airsoft Megastore Armory Full Metal AMR-4 A1 EBB AEG w/ MOSFET - BLACK *****
GREAT! Blowback not working?

"I just got it yesterday, very very sturdy but also a little shorter than i expected... I have only put a few rnds through it and I heard that the blowback dosent function after about 100 shots, but very awesome over all! I do recommend that you do buy a Rail system for it though. Pros: Full metal Mosfet enhanced Retractable stock Awesome accuracy and FPS Cons Short(er) Have to buy a Rail system for more customization(besides top rail) Doesn't come with a battery Blowback going dead?"

5 Airsoft Megastore Armory Full Metal AMR-4 A1 EBB AEG w/ MOSFET - BLACK *****

"This gun is sweet! I went to a war the other day and one my friends had the KWA M4A1 and I had this gun. They were pretty much the same thing, except mine was blowback and a lot cheaper. At 180 (I got mine on black Friday for 140) it is one of the best guns that I have every seen and owned. Mosfet runs good on it, tango down grip feels... right, and it can still have the full customization. The two things I don't like about this is 1. The glossy finish on the gun's handguard 2. the blowback is not working, after about 100-200 shots it just doesn't seem to work ( I might have a dud though). I will be contacting a-meg about this problem. Good gun over all though Pros Full metal Mosfet runs beautifully runs on a 9.6v at about 15rps Tango down grip feels like a KWA detachable carrying handle to either keep on or put your own sights Cons Blowback failed on it after 100 shots (I think I just got a dud) Handguard has a glossy look to it (I was gonna change it to MOE anyway)"

4 Airsoft Megastore Armory Full Metal AMR-4 A1 EBB AEG w/ MOSFET - BLACK *****
Interesting rifle

"So right after seeing this gun i immediatley wanted to pick it up due to the fact that the price and the specs were amazing. I started out shooting this with .20s as recommended and was happy with the fps, but the accuracy wasn't that great at ranges. i dropped some .25s in to a mag and started shooting. the accuracy was phenomenal! but unfortunately the stock hop up could not get as much distance anymore and the fps seemed to drop immensely. i did not chrono it but from just using my eyes and comparing it with .20s and .25s i would say it dropped at least to 350 fps if not lower. i play outdoors so the range and fps drop sucks but i called customer service and they helped me pick out a new hop up system which is currently being shipped to my house. i will write an update on how it shoots after i install it. other than the hop up not being the best the rest of the gun is perfect. it is sturdy, a good realistic weight, easy to put a free float barrel onto, and has a very ergonomic grip. if you want more power then get a more powerful spring but that may cause your gears to strip. if you want a higher rate of fire put a battery with more voltage onto it. just some tips if you are new to the game."

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
