EMG x Daniel Defense DDM4 AEG (by Cyma – Platinum QBS Gearbox DE/Black – CM105DDL-BD)

The Daniel Defense DDM4 AEG is an EMG-licensed electric rifle built by Cyma, pairing genuine Daniel Defense branding with a field-ready Version 2 metal gearbox and CNC quad rail handguard. Finished in Dark Earth and Black, this AEG rifle gives UK skirmishers and milsim players a realistic, upgrade-friendly primary with a Platinum QBS quick-change spring system, adjustable hop-up and a 150-round mid-cap magazine straight out of the box.

Key Features

• EMG-licensed Daniel Defense branding – roll marks, laser engravings and a weather-resistant matte black finish give this AEG the authentic look of a genuine DDM4 build.
• CNC-machined Daniel Defense quad rail handguard – a free-float design that keeps the barrel unobstructed for consistent accuracy and gives full-length rail space for optics, grips and lights.
• Version 2 metal gearbox with Platinum QBS quick-change spring system – swap springs without stripping the receiver, making rate-of-fire and power adjustments fast between site visits.
• Adjustable stock, 755mm–840mm – tailor the overall length and cheek weld for different body sizes and loadouts.
• 150-round mid-cap magazine – compatible with Tokyo Marui, CCCP and Big Foot G&P magazines, so spares are easy to source.
• Dual rate of fire, 17rps on 7.4v / 28rps on 11.1v – runs efficiently on a small LiPo and picks up pace when you step up the voltage.
• Long-type motor with adjustable hop-up – reliable cycling and a tunable back-spin for a flatter BB trajectory.
• Deans-connector 7.4v LiPo wiring – rear-wired for a clean build, ready for a small LiPo battery (battery and charger not included).

Real-World Use Cases

• Woodland & CQB skirmish – the 2680g build and adjustable stock suit both open-field engagements and tighter CQB layouts at UK sites, provided you check the venue’s FPS/joule limit before your game.
• Milsim loadouts – Daniel Defense styling and a genuine quad rail handguard make this a strong PMC/modern-military impression piece for UKARA-registered milsim weekends.
• First upgrade from a starter AEG – the TM-compatible Version 2 gearbox and QBS spring system mean site-limit tuning and future internal upgrades don’t require a full teardown.

Compatibility & Upgrades

This DDM4 AEG runs on Tokyo Marui-pattern mid-cap magazines, so genuine TM, CCCP and Big Foot G&P magazines drop straight in alongside the included 150-round mid-cap. Power comes from a small 7.4v LiPo battery wired to a Deans connector – pick from our range of compatible batteries sized for the stock tube. The TM-compatible Version 2 metal gearbox and QBS spring system make it a straightforward platform for hop-up units, spring changes and other internal upgrades as your skirmishing needs change. Feed it with quality 6mm BBs suited to your site’s hop-up settings and FPS limit.

UK Legal & Site Notes

This is a Realistic Imitation Firearm (RIF) and is sold only to buyers aged 18 and over. UK law requires a valid defence to purchase a two-tone or realistically coloured airsoft RIF – typically UKARA registration or another accepted VCRA defence such as a skirmish site membership, letter or field ticket. Always confirm your site’s FPS/joule limit before your first game; this AEG’s power output should be checked and, if needed, adjusted using the QBS spring system to stay within your venue’s rules.
