- Full metal construction
- Upgraded Gen.2 internals
- Gorgeous real wood furniture
If you're after a rock-solid AK replica with the classic aesthetic, the CYMA Gen.2 CM.048M AKM AEG is a fine choice. A stunner of a full-metal build with real wood furniture, this AK is styled after the AKM, the modernised Kalashnikov which entered service in 1956 and is still favoured by certain Spetsnaz units to this day.
Inside, this Gen.2 build is packing a lot of punch for the price, equipped with a CYMA V3 MOSFET, a high-torque motor, a CNC aluminium piston and cylinder head, and a polycarbonate piston with steel teeth. The motor is a potent high-torque example, resulting in a speedy trigger response in semi-auto, with lock-ups eliminated thanks to the in-line MOSFET. Whether you want a classic AK to fill out your collection or a robust, old-school skirmish piece, the CYMA Gen.2 CM.048M AKM AEG will do the trick!

Platform Details
Starting at the tip of the barrel, we can find a classic AKM-style "slant" muzzle brake, intended in the real AK to counteract the jarring recoil forces of the massive AK bolt carrier by redirecting the muzzle blast. The brake may look like it is not straight, but we assure you this is all part of the utilitarian AK design.
The slant brake mounts to 14mm CCW male threads at the tip of the 16.3-inch alloy outer barrel and can be swapped out for a suppressor or tracer unit if you are going for more of a Spetsnaz look for your AK. We recommend a PBS-1 Suppressor if you want the authentic Soviet look.
The front sight mounts directly to the outer barrel and provides an adjustable front post with protective wings to ensure an accidental bump or scrape does not render your sights useless. As part of the classic AK aesthetic, we can find a dummy cleaning rod running parallel to the outer barrel. This isn't intended for cleaning an Airsoft barrel, but it is an important part of the iconic AK silhouette.
Moving further down the outer barrel, we come to the dummy gas block. This connects to the gas tube, which meets the real wood upper handguard via a steel handguard cap. The lower handguard surrounds the outer barrel and is retained by its own steel handguard cap, which includes a sling point on the left side, ideally for hook-type slings. The handguards are constructed from real wood, with a deep and varied wood grain and an ultra-realistic feel.
The trunnion block follows just behind, providing the mounting point for the classic AK tangent rear iron sight, which provides multiple graduations for adjustment and a fine rear sight notch to align with the front sight post. The sight can be adjusted by pressing the buttons on either side of the sight notch and moving the notch back and forth on its base. This sight type benefits over aperture sights in its field of view, allowing you to track moving targets more effectively and avoid tunnel vision.
The lever on the right side of the trunnion block is the handguard disassembly lever. This lever allows you to quickly remove the upper handguard and gas tube, just like a real AKM. This is one of the many perks of using the VFC-style external construction over the TM style: you can strip it like a real AK for extra nerd points!
Next up, we find the receiver, which is constructed from authentic stamped steel. The receiver has standard AK-style controls on the right side, with a stamped steel fire selector lever which doubles as a dust cover when in safe mode, and a charging handle attached to an authentic black dummy bolt carrier, also made from hefty, realistic steel.
In typical AK style, the first position on the fire selector is fully automatic, and the lowermost position is semi-automatic. Each fire mode is denoted by a crisply engraved authentic Russian Cyrillic marking, adding extra realism to this already very realistic AK.
On the left side, we can find an AK quick-detach mounting rail, allowing for authentic Russian scopes to be mounted, or 20mm Picatinny rail mounts if you prefer a more modern Western optic. The receiver also provides several authentic rivets, all found in the correct place for a 70s-era AKM. The receiver top cover is also constructed from stamped steel and is the appropriate design for an AKM, with ribs stamped into the upper surface to provide additional strength while keeping the material thin and lightweight.
To access the adjustable HOP-up unit, simply hold the charging handle to the rear to reveal the alloy slider adjustable HOP-up unit. The slider unit is known as one of the best designs out there, and that is the reason this unit has not changed in design since the original Tokyo Marui AK-47 AEG. To increase the HOP-up effect, simply move the slider rearwards. Returning the slider to the front will reduce the HOP-up to its lowest setting.
The pistol grip is a standard AKM-type pistol grip made from high-density polymer, featuring diamond checkering on either side to ensure the rifle stays firmly in your grasp in any weather condition. Just ahead of the pistol grip, we can find the trigger guard and magazine release assembly, constructed from steel to provide solid magazine locking and ample rigidity.
The magazine release is placed in the centre of the receiver and is accessible from either side of the AEG, offering both left and right-handed users an easy reload process. The magazine retention system of the AK platform is a "rock and lock" motion, requiring you to first index the front "hook" on the magazine inside the receiver, then rock the magazine to engage the catch.
The stock is made from real wood and has an authentic colouration for AK furniture, with a varied grain and satin finish. The wood both looks great and perfectly matches the handguard, providing the most realistic feel from front to rear. The bottom of the stock also features a steel sling loop, which pairs well with the front sling point on the lower handguard cap, providing appropriate mounting apparatus for a two-point sling, but ideally suited to an AK-47/74 sling.
The butt plate is made from stamped steel and is appropriately untextured to match the real thing. Those accustomed to textured rubber butt plates will find that there is no room for comfort in this utilitarian design. However, you can add a rubber butt plate extension to experience a touch of Western luxury while keeping the Soviet vibes of the AKM.
The battery compartment is inside the real wood stock, accessible by removing the two screws holding the butt plate in place. With the screws removed, you can lift the butt plate free, revealing a Deans battery connector inside. We recommend a 7.4V 1450mAh LiPo in crane/nunchuck configuration for an easy fit and great performance.
Internals
Internally, we are in for a real treat with this Gen.2 variant of the CM.048. The gearbox has been fully revamped and is now equipped with CYMA's V3 MOSFET, enhancing trigger response and preventing trigger lockups if you shoot semi-auto rapidly.
Inside the reinforced V3 gearbox, we're treated to 18:1 ratio steel gears running on 8mm ball bearing bushings, backed up by a potent high-torque motor with Neodymium magnets. This provides a snappy cyclic rate in both fire modes while reducing wear and tear on the gearbox shell through its low-friction bushings.
Also inside is a CNC aluminium piston head and cylinder head, preventing air leaks and improving reliability in the long term. The piston also has a full rack of steel teeth, ensuring it can go the distance with the rest of the build!

Joule Charts
Special Instructions
These tables can be used as a reference to see if the BB weight you are using will be over acceptable joule limits at some Airsoft Sites in the UK. To check if the weight can be used chrono your weapon using the BB you intend to use, and then compare it to the chart.
FPS, Power and Joule Limits can vary from site to site, so please get in touch with where you're going to play with in advance to avoid disappointment.
Suggested limits are based on Joulage Limit rules used at Halo Mill: Proving Grounds, with a 350fps limit for Automatic Replicas, 400fps for Semi-Automatic Replicas, and 500fps for Bolt Action Replicas.
Tap the tabs below to open the relevant chart for your replica.
This table should be used for reference and cannot be used to check one weight against another, as the weight of the BB affects the power.
In order to check if the BB can be used with your replica chronograph using the weight you wish to use and then compare it against the table.
Every time you change weights you will need to re-chrono and check against the table. This is not a conversion chart between weights.
Suggested limits are based on Joulage Limit rules used Halo Mill: Proving Grounds, and is the equivalent of 350fps, using 0.20g BB resulting in an upper limit of 1.14j.
