Our take:  The NEW M4 RIS AEG by CYMA rocks solid internal parts and provides airsoft players with a modular platform for taking down targets in both CQB and outdoor scenarios.  Powered by a hard-hitting Version 2 gearbox, this M4 RIS shoots between 350-370 FPS (w/ 0.20g BBs) and yields incredibly tight groupings.  Combined with its high performance internals and modular capabilities, CYMA’s M4 RIS is a force to be reckoned with in any airsoft game!

CYMA, which is known for their wide variety of AK47 style AEGs, designed this M4 for both indoor and outdoor fields.  This AEG is fitted with a fully adjustable hop-up unit to ensure each round hits its target.  For optimal tactical advantage, this rifle sports more than 30 inches of rail space that allows players to attach a number of mounted accessories, including tactical foregrips, flashlights and laser units.  The front and rear iron sights are adjustable for windage and elevation, with the option to easily remove the carry handle to make space to attach aftermarket optics for improved accuracy.

The X-Tac Polymer Difference
This new CYMA Gen-4 M4 is equipped with an advanced X-Tac Polymer body, built to deliver ultra-maneuverability with its lightweight formation, while being able to with extreme wear and tear in the playing field.  Formulated with an advanced polymer composite, CYMA's new X-Tac Polymer bodies deliver never-before-seen reliability and performance for an airsoft rifle under $150, turning the airsoft market on its head.  Available exclusively at Airsoft Megastore, buy your new CYMA M4 today and experience the X-Tac Difference!

Maneuverability comes easy for CYMA’s M4 RIS as it is equipped a durable polymer crane stock that can be adjusted in six positions, improving the overall ergonomics of this rifle.  The retractable stock also makes it easy for operators to turn tight corners and clear buildings.  This M4 AEG also features a full metal outer barrel, buffer tube and charging handle to improve the overall reliability and durability of this rifle.  Additionally this AEG is built with a highly durable polymer upper and lower receiver, making it lightweight and thus reducing operator fatigue in longer games.

The NEW CYMA M4 RIS is a top-of-the-line AEG for its price and is compatible with Version 2 internal parts, giving you the option for upgrades and modifications in the future.  This rifle is perfect for all airsoft players and comes with everything you need in the box, including a high capacity magazine, bag of BBs, battery and charger!

5 CYMA M4 RIS Full Metal Gearbox Airsoft AEG Rifle - X-Tac Polymer *****
Philip Lutz III

"This gun is absolutely amazing. Says it shoots 40 to 50 meters on the box, I think it does more. Hard hitting, battery on mine has lasted for a week (hour a day use or so) and I could not have asked for a better primary. HIGHLY RECOMMEND"

Great Gun!

"For starters it is a great gun. Hard Hitting, Accurate, and has the real weight of a m4. Gearbox works smoothly, No jams, Hop up works great. My only problem with it is that about a week after receiving it, it started shooting wrong. At first I thought it was a gearbox problem but after contacting customer service it turned out that it had run out of "oil". After cleaning the barrel and spraying silicon oil into the loading dock the gun worked just fine. I would suggest this gun to anybody looking for a quality beginner or intermediate gun."

CYMA M4 RIS Xtac polymer

"Spectacular AEG. Do not waste your money on a so called "high end" airsoft guns. I've been successful in firefights against KWAs and even Polarstars with this AEG. This airsoft gun has incredible range and firepower, and the polymer is extremely durable. In the buildings or on the field, this airsoft gun is the right buy for anyone. "

This is a amazing gun

"The guns looks amazing and the rails make it possible to customize the gun a whole lot. The carrying handle/sight is removable and a great place to put a Scope. The FPS is nice and the accuracy is great. I think this is a great gun for beginners and pro players too."

Great gun

"This think shoots great out of the box and it feels realistic. Also it has rails and a nice crane stock all under 150. It's great to upgrade and to use as a backup just as it is."

Good to Start

"Great weapon for the new airsoft gamer. It delivers a light weight and durable weapon platform ready to accept many attachments. It shoots very well out of the box. I would suggest upgrading the hop up to a metal one though as the hop up broke in mine in the 3rd day of gaming with it. I also is not very compatible with other rail systems or m4 bodies. they have their own barrel/delta ring mounting system. It's very strange to me. If you're looking to get into airsoft and looking for a cheap option that will have you up to par with the local players look no further!"

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
