- Alloy slide / Polymer frame
- MOSFET Edition - Snappy!
- Semi / full automatic modes
If you love a 1990s icon in winter-proof AEP form, the CYMA CM.126S MOSFET Edition will put a big smile in your face! Made with a hefty alloy slide and a high-density polymer frame, this build replicates the iconic B9 pistol, once standard issue to the US Army and favoured by action heroes like John Maclaine and the Boondock Saints.
This, the MOSFET edition of the CM.126, boasts a faster rate of fire than the original and a snappier-feeling trigger thanks to electrical efficiency improvements and the MOSFET's cycle completion function. Whether you need an affordable full-auto BB hose as a backup to your sniper rifle or you need a military-style sidearm for winter skirmishes, when GBBs can't cut it, the CYMA CM.126S MOSFET Edition is a solid choice!

Description
Quick Start Guide
- Charge your battery. This set does NOT include a battery or charger. We recommend a 7.4V 680mAh LiPo battery for this pistol and a LiPo balance charger. To charge this battery, plug the Balance connector (small white connector) into the corresponding port on your balance charger. Charging will stop when your battery is fully charged, but you should never leave it on charge unattended.
- Remove the slide to access the battery compartment. To do this, push down the mock slide release catch on the centre left of the frame, then pull back the mock hammer at the rear and lift the slide off towards the front.
- Put on eye protection. As soon as the pistol is powered, the risk of a discharge is present, even with no magazine inserted. When shooting, ensure both the shooter and any spectators are wearing Airsoft-rated eye protection.
- Insert your battery. Beneath the outer barrel, you’ll see a short length of wire with a mini-Deans battery connector. Index the connector of your battery with the connector of the AEP, and push it in until firm.
- Replace the slide. With your wiring tucked in neatly, place the slide back onto the pistol, being careful to index the barrel with the port in the front of the slide and holding the hammer back while reinstalling it.
- Load your magazine. Press the magazine release catch if your mag is inserted. Next, fill it up through the top, using a speed loader or by hand. We recommend either 0.20g BBs or 0.25g BBs for this AEP.
- With your eye protection on and the magazine filled, insert the magazine, and you’re ready to shoot. Never shoot Airsoft ammo beyond your property, at animals, or at humans who are not participating in an Airsoft skirmish on private land.
Platform Details
Starting at the front, we can find the outer barrel protruding slightly from the front of the slide, an unthreaded example with mock rifling grooves to give the enemy players a realistic view.
Moving rearwards, we come to the slide, made from hefty alloy, providing realistic weight and the cold feel of metal in the hands. On top, we have open iron sights which perfectly match the real B9 pistol, great sights for rapid acquisition and short-range firefights.
At the rear of the slide, we have a two-position fire selector switch, with the upper mode providing semi-automatic fire and the lower mode providing full-auto. This is one of the biggest advantages of AEPs: an effective full-auto mode with far better consistency and accuracy than full-auto GBB pistols.
Moving down, we come to the frame, made from robust high-density polymer with all the realistic details a B9 fan will love. On the right side, we have the dummy disassembly lever, non-functional but nonetheless included to complete the realistic look.
Next up on the right side, we have the mock slide lock/release. This doesn’t function the same way as a GBB or real B9; instead, pushing it down unlocks the slide, allowing it to be removed with the hammer held back for HOP-up adjuster and battery compartment access.
To remove the slide, push the slide lock lever down. Next, hold back the mock hammer at the rear of the frame. With this done, you can lift the slide off, revealing the gear-style HOP-up adjuster on the left side. Turning the adjuster allows you to tune the amount of backspin applied to your BBs, altering it for different BB weights and seeking the flattest possible trajectory.
Over on the right side, we have the functional safety catch, a sliding switch which locks the trigger in the rearmost position, freeing it up when pushed forward. This safety can easily be used from a firing grip, and while it doesn’t appear on the real B9, it's a great feature for safety, both in-game and at home.
Moving down, we can see the textured grip panels, providing plenty of traction for wet weather use and a comfortable shape for most hand sizes. The front and rear of the grip also feature linear grooves, adding to its superb all-weather handling qualities. The magazine release is on the left side, where the trigger guard meets the grip; a push-button design easily accessed from a firing grip.
At the base of the grip, we’re treated to a lanyard loop, a common feature on 1990s-era real steel pistols. This loop is designed to be used with a retention lanyard, tethering your pistol to your belt so it never goes missing if it slips from your holster.

Special Instructions
Safe removal of the slide
As you look at the pistol showing the slide lock/release lever, this is most important in order to not damage the pistol's frame. With the pistol in your right hand with the barrel pointing to the left, move this lever downward; it only moves a little bit, but in doing this, it allows the top slide to be moved forward around 5 mm. This is crucial in order to remove the top slide correctly without breaking the fragile rear tags that are part of the gun lower frame.
Once you have moved the slide forward on its frame, lift it up and forward to remove it from the pistol, and you can then fit your battery.
To re-fit the slide, please make sure you position the slide onto the frame in the same forward position before moving the slide backwards into its correct position. Once the slide is backward as far as it will go, ONLY THEN, move the slide lock/slide release lever back into position.
DO NOT force the slide straight down onto the gun; doing this will break the two tabs that hold the slide onto the gun and will invalidate any warranty on the pistol.

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.
