JG M5K RIS Full Metal Modular Airsoft AEG Submachine Gun SMG

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!

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.

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.
