NOTE: This item is exempt from expedited shipment.

Our take:  The New JG M5K RIS Airsoft Sub-Machine Gun (SMG) AEG is by far one of the most compact and realistic CQB airsoft guns on the market.  Just over twelve inches long, this M5K is easy to wield in close quarters environments and is perfect for high speed room clearing.  The M5K style SMG was originally developed for covert operatives and security details that needed maximum firepower in a compact and concealable size.  JG’s M5K can be used either as a compact and lightweight primary, thanks to its accuracy and range, or as a compact fully automatic secondary for snipers or other support positions.  Unlike the traditional M5K, the NEW JG M5K RIS features a full metal quad rail system providing plenty of space for customizing the airsoft SMG with aftermarket optics, lasers, lights, fore grips, and other accessories.  Highly versatile, extremely compact, and incredibly realistic, the NEW JG M5K RIS AEG is a must have for any serious airsoft player.

Weighing just over five pounds, the JG M5K RIS is incredibly similar to its real steel counterpart.  JG has updated the design of the original M5K with the addition of a full metal rail system, which provides over 18 inches of combined rail space!  The upper receiver, mock charging handle, magazine, iron sights, and rail system are all crafted from high grade metal, giving this compact AEG a uniquely realistic look and feel.  Designed to be easily concealed, the M5K RIS features a metal single point sling mount which allows you to comfortably carry the airsoft gun hands free.  Another great feature of the M5K is its ambidextrous selector switch, making the gun easy to use for both right and left handed shooters.  The JG M5K RIS’s rugged construction and realistic design sets it above most other compact AEGs on the market.

Though the JG M5K RIS is designed for CQB length engagements, it can easily hold its own in outdoor environments.  Unlike other M5K AEGs on the market, the JG M5K RIS features a fully adjustable hop-up, allowing you to perfectly dial in your shots.  It also features a full metal Version 3 gearbox with premium grade internals, making this AEG extremely reliable.  With a CQB field “legal” muzzle velocity (shooting 330 FPS w/ 0.20g BBs), the JG M5K RIS is a must have for any serious indoor CQB field airsoft player!

The NEW JG M5K RIS by far one of the most realistic and reliable CQB AEGs on the market, and is sure to dominate in any close quarters arena.  Whether you are looking for a compact primary or a full auto capable secondary that is ready to go right out of the box, the NEW JG M5K RIS AEG is perfect for you!

Operation:  Electric Automatic

Muzzle Velocity:  310-330 FPS (w/ 0.20g BBs)

Outer Barrel Threading:  N/A
Battery Type:  8.4V NiMH Stick Type
Hop-Up:  Fully Adjustable
Weight:  5 lbs
Overall Length:  12.5” in.

NOTE:  The full metal rail system MUST BE REMOVED from the AEG in order to correctly install the battery.  This can be done easily by unscrewing all seven screws on the left side of the gun (make sure to not misplace the screws or nuts that hold the rail system in place).  The battery must be inserted with the connector facing towards the barrel of the gun.  The white hop-up adjustment lever is located along the left side of the inner barrel (inside of the rail system).

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, magazine, battery, charger, instruction manual

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 JG M5K RIS Full Metal Modular Airsoft AEG Submachine Gun SMG *****
Great gun

"This is a great gun for the money I've had it for 2 and half months and I love it. Pros heavy , iron sights are good, great rof, durable, realistic, a lot of rail space for mounting . Cons. The magazine that comes with it is good but low ammo capacity, at first it hard to close the back plate, all of the cons are very minor....I do recommend this gun to anyone."

Awesome Gun


This gun is heavy and feels great in your hands. 
Pros:Heavy, Accurate, Solid, Looks so boss, Loud, mostly metal, compact for CQB or if you run a lot while playing, good ROF, Good range, sights work, the battery loads from the back so you dont have to take the rail off but it is still a pain to load it.
Cons:The top rail is like a millimeter to thin so you have to re-enforce your mounts, some old mp5 mags dont fit it, the gun jams on semi randomly,  battery is hard to load, battery is green so you have to tape it black, the cocking device just gets the batteryout, 
This gun is pretty awesome but i am sure it will be hard to upgrade.
Hey! Thanks for the review! We are glad to hear that you are enjoying your SMG. Very sorry about the cons you have listed. Although we cannot control some of those things, 100% PREMIUM GRADE SILICONE OIL will help your SMG to not jam. If you have any concerns please contact us!

4 JG M5K RIS Full Metal Modular Airsoft AEG Submachine Gun SMG *****

"Pros: Compact, Full Metal=long lifespan, very realistic. Manual is very helpful (minus the hilariously bad english translation). It's especially useful for take-downs and general part cataloging. Very satisfying to reload and use. Does have replacement parts. Cons: Rather heavy, unless you remove the rail system. Replacement part compatibility varies. Magazine has only a good amount capacity. Ugly: Cocking handle broke. As it turns out, the metal that makes up the upper receiver (not the internals) may be a mix of a metal and some other material. This resulted in the head of the handle breaking off after being knocked using the "HK Slap". If you're constantly using the cocking handle on guns, either get some other gun or be careful with this one. Overall: Pretty good."

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
