CYMA CM.121S Desert Eagle Advanced MOSFET Edition

  • Integrated LiPO
  • MOSFET Edition
  • High Rate of Fire

The CYMA CM.121S is a replica of the fearsome Desert Eagle in Airsoft Electric Pistol form with a twist. This AEP is built around a MOSFET and an integrated LiPo battery which leaves you with a savage Rate of Fire and much higher performance than a normal AEP.

Full description


This Airsoft Electric Pistol is based on the fearsome Desert Eagle. The main feature of the pistol is the MOSFET and integrated LiPo battery which makes them easy to run, and higher performance than your typical AEP. It features both Semi and Full Automatic fire modes, which are selected via the marked fire selector at the rear of the frame. The gun has a trigger lock safety which can be engaged by pressing the button above the trigger guard and sliding what would be the slide release on the other side to the safe position. It also has an adjustable HOP which allows you to backspin the BBs to increase range at the cost of accuracy. To makes adjustments, remove the top slide by pulling down the hammer and pulling the slide forwards and up. The HOP is then adjusted by the gear-style adjustment wheel on the side. The magazine holds a total of 30rnds which is more than enough to spray at the enemy in a panic, or to make a competitive sidearm for CQB situations. Please note that this AEP accepts a different magazine to standard AEPs.

The integrated LiPo Battery should be charged using a compatible LiPo Charger (with balance ports) in a Fire Proof area.

If you're looking for an easy to use and dependable sidearm as a backup or primary weapon for CQB situations, which has consistent performance due to not having to mess around with gas, then the CYMA CM.121S MOSFET Edition is the perfect sidearm for you.

Special Instruction

Please note that the battery is built into the replica and can not be swapped out at a skirmish. This replica is perfect as a sidearm rather than a main weapon as standard, but could be modified to have swappable battery. If such a modification is made please note it will void your warranty.

Please note that this AEP accepts a different magazine to standard AEPs.

The externals of the replica are metal where they would be on the real world gun. This includes things like the outer barrel, handguard, and receiver. If a real world gun has polymer parts then the gun will still be marked as full metal externals, examples of this would be an M4, where the Stock and Pistol grip are always made from Polymer.
