CYBERGUN X FN® M249 MINIMI® “MIDDLEWEIGHT” SAW AIRSOFT AEG – A&K MK II / BLACK
FN Licensed • Middleweight M249 Construction • Reinforced A&K Gearbox • Full-Length Polymer Stock • 2400rd Sound-Activated Box Magazine • Steel Folding Bipod
CYBERGUN X FN // M249 MINIMI // MK II // MIDDLEWEIGHT // A&K // SUPPORT AEG // 2400RD BOX MAG // BLACK
Get the unmistakable profile of a full-size M249 support weapon without carrying all the weight of A&K’s Standard series with the Cybergun x FN M249 MINIMI “Middleweight” SAW Airsoft AEG by A&K – MK II / Black.
Designed as the middle ground between the heavyweight Standard M249 and lightweight Featherweight series, the A&K M249 Middleweight MK II removes approximately 2 lbs of external weight while retaining the dedicated reinforced A&K M249 gearbox architecture that makes the platform so appealing to support-gunner enthusiasts.
The MK II configuration stands apart with its classic full-length polymer stock, giving the rifle a traditional full-size M249 silhouette. Combine that with FN licensing, a high-strength polymer receiver, reinforced metal gearbox, 8mm bearings, heavy-duty steel gears, steel folding bipod, aluminum outer barrel, and an included 2400-round sound-activated box magazine, and you have a purpose-built support AEG ready for extended airsoft games.
01 // FN® LICENSED M249 MINIMI® PLATFORM
The M249 MINIMI is one of the most recognizable modern support-weapon designs, and this airsoft recreation carries official FN licensing through Cybergun.
The MK II configuration captures the traditional full-size M249 appearance, complete with its long fixed-style stock, carry handle, bipod, heat-shield profile, and large box magazine.
For players who want their support AEG to look distinctly different from an oversized rifle, the M249 delivers unmistakable SAW styling.
02 // MIDDLEWEIGHT DESIGN // APPROX. 2 LBS LIGHTER
Support weapons can become exhausting during long airsoft events, especially when combined with thousands of BBs, batteries, and additional equipment.
The Middleweight series addresses this by reducing weight in key external areas.
A&K uses high-strength polymer for components including the:
Receiver
Dust Cover
Handguard
Heat Shield
Gas Block
According to the supplied specifications, this makes the Middleweight approximately 2 lbs lighter than its Standard-series counterpart.
You retain the size and presence of an M249 while reducing unnecessary external weight.
03 // FULL-LENGTH MK II POLYMER STOCK
One of the defining features of this specific model is the:
FULL-LENGTH POLYMER STOCK
Unlike compact or retractable M249 configurations, the MK II retains the classic full-size rear profile associated with traditional M249 variants.
For players building a classic support-gunner or MilSim-inspired loadout, the full stock helps complete the unmistakable appearance.
Polymer construction also contributes to the Middleweight’s overall weight-saving strategy.
04 // REINFORCED A&K M249 GEARBOX
The most important distinction between the Middleweight and lighter alternatives is what’s inside.
A&K retains its dedicated reinforced M249 metal gearbox shell, providing a robust foundation designed around the demands of a support AEG.
The gearbox features:
8MM BEARINGS
HEAVY-DUTY STEEL GEARS
Retaining the established A&K M249 gearbox architecture also means the rifle remains compatible with many A&K M249-specific gearbox components, making future servicing and compatible upgrades considerably easier.
05 // UPDATED INTERNALS FOR MODERN BATTERIES
A&K has updated the internal system to better accommodate modern higher-discharge battery technologies, including appropriate LiPo and Li-Ion batteries.
This is especially useful on a support-style AEG, where the drivetrain may experience longer firing cycles than a conventional rifle platform.
Battery compatibility still matters. Always verify the correct voltage, discharge rating, connector type, dimensions, and manufacturer recommendations before selecting a battery.
06 // 2400RD SOUND-ACTIVATED BOX MAGAZINE
A proper support AEG needs serious ammunition capacity.
Included with the M249 Middleweight MK II is a massive:
2400-ROUND SOUND-ACTIVATED BOX MAGAZINE
The large reservoir dramatically reduces the frequency of reloads during extended games.
Its sound-activated feeding system is designed to assist with keeping BBs supplied to the rifle during operation, providing a more convenient solution than repeatedly winding a conventional high-cap magazine.
For support-oriented gameplay, 2400 rounds gives the M249 the capacity expected from a dedicated SAW-style airsoft platform.
07 // M4 / M16 MAGAZINE COMPATIBILITY
The M249 offers another major advantage:
COMPATIBILITY WITH STANDARD M4 / M16 AEG MAGAZINES
Compatible M4-style magazines can serve as an alternative to the box magazine.
This can be particularly convenient if the box magazine needs to be removed or refilled.
For teams already carrying M4 AEG magazines, the shared magazine format can also provide useful flexibility during longer games.
08 // STEEL BIPOD + REINFORCED EXTERNAL COMPONENTS
Weight reduction doesn’t mean every component has been converted to polymer.
A&K retains metal construction in important areas.
The Middleweight MK II features an aluminum outer barrel, steel carry handle, and steel folding bipod.
The bipod can be deployed for supported positions and folded away when moving.
This combination gives the rifle metal reinforcement where it matters while polymer components help keep the overall platform more manageable.

FIELD NOTE // SUPPORT AEG MAINTENANCE
Support-style AEGs can experience longer firing cycles and greater ammunition use than conventional rifles. Proper battery selection, gearbox maintenance, clean BBs, and box-magazine care can help maintain consistent performance.
Avoid unnecessarily prolonged firing cycles that can create excessive heat in the motor and electrical system. Always follow your airsoft field’s specific support-weapon rules and firing-mode requirements.
