Description
Cyma CM623 M4 M-Lok AEG with Mosfet and QD Spring – Two-Tone Blue (Inc. Battery and Charger)
The CM623 is an M4-pattern electric rifle from Cyma, the long-established Chinese maker known for dependable, affordable AEGs. It follows the familiar AR/M4 layout with an M-Lok handguard, and this version comes finished in two-tone blue. It is sold here as a ready-to-play package with a battery and charger.
Build and performance
The body is made from nylon fibre polymer, which keeps the weight manageable while standing up to regular skirmishing. Inside is a Version 2 gearbox driven by a long-type motor, with a mosfet fitted to protect the trigger contacts and sharpen trigger response. A quick-change (QD) spring system lets you swap the spring without stripping the gearbox, handy if you need to meet different site limits. Range is tuned through a variable hop-up, and the rifle fires in semi and full auto.

Good to know
Charge the supplied battery fully before first use, and use 0.20g or heavier quality BBs for consistent results. Thanks to the QD spring, adjusting power for a particular site is straightforward. This is a two-tone coloured version, so it can be bought without a UKARA defence, although buyers must be 18 or over. Always wear eye protection and check your site’s power limits.
