Our take:  This NEW Full Metal M4 RIS AEG is manufactured by CYMA, long known for their reliable and affordable airsoft electric guns, and features a hard hitting muzzle velocity right out of the box!  This realistic looking airsoft M4 Carbine features a full metal external design with a railed handguard, which allows you to fully customize this AEG to meet your mission needs.  With an included battery, magazine, and charger this complete AEG package is an incredible value and provides you with everything you need to field the CYMA M4 RIS AEG right out of the box!

CYMA has finally decided to bring their highly regarded M4 AEG series to the American market, and has specifically designed their AEGs to meet U.S. airsoft players' rigorous demands.  Each CYMA M4 RIS AEG is constructed from high grade aluminum alloy, giving the airsoft carbine an authentic look and feel.  These AEGs can easily withstand the high stress conditions of fast paced, outdoor airsoft games, and are designed to last. 

Equipped with a full metal Version 2 gearbox with a factory installed M130 spring, as well as a high torque motor, this AEG shoots well over 400 FPS right out of the box!  This AEG is designed for medium to long range outdoor airsoft combat, and thanks to its full metal hop-up unit and precision inner barrel, this AEG can knock down targets accurately at 200 feet!  This AEG's performance easily rivals many of the more expensive M4 AEGs on the market, making this AEG an incredible value!

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, 300rd Magazine, 8.4v Nunchuck Battery, Wall Charger

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 CYMA Full Metal M4 RIS AEG Airsoft Rifle w/ Ultra High Torque Motor *****
This is a fantastic airsoft gun!

"I ordered this gun as my first serious airsoft gun. I absolutely love it. It is very accurate after you adjust the hop up and really fits my play style. I am a rough player meaning that I'm not very careful with my gun during a war. I have tripped and my gun threw about 20 feet into a pile of rocks and I went and picked it back up and shot an enemy. Extremely durable, tough exterior, easy and countless customization options and an overall amazing gun. I will be using this gun for a very long time."

"Nice gun, hard hitting, easy to strip, and reliable. I upgraded it with just a 9.6 battery, bipod and forgrip, a great support and MOUT weapon"

Great gun

"Works just like the CQBR version and is still pretty heavy, I would get a sling on it if your going to put a lot of equipment on it. The FPS is great for bigginer shooters, I would raise the FPS up with a 9.6 butterfly battery and an M140 spring to raise it up, I did and it was firing 437 FPS using .2 grams. Pros: Realistic feel and look Good accuracy Full metal Very Durable Easy to customize internal and externally Cons: When I got it out of the box the first time, the rail system was wiggled a bit so it was annoying during fights. Over all, the shooting is great for starters, but the weight is for the vets."

Good, but could be better.

"I got this gun and waited over 4 hours for the battery to charge. I immediately wanted to shoot it so I did but was disappointed when I found out the ROF was so slow. It is not 15 rps like advertised. It looks good, feels good, and it's pretty realistic but the ROF was just disappointing. Going to pick a 9.6 up tomorrow and try it again."

great gun just needs some work

" I got this gun its greay but the cran stock is verry hard to get the cap on and its verry hard to swich the wireing to the front. I highly suggest that you get a smart charger and a 9 volt battery there are better guns for less."

Semi auto poorly functioning

"The gun feels realistic in construction and weight but, actual function leaves much to be desired. Full auto cycles somewhat slowly and semi auto jams predictably every 2-3 rounds. This gun is getting returned after only zeroing the irons. Hopefully it can be repaired and doesn't have inherent design flaws."

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
