The Edge series are a new line of replicas from Specna Arms which combine their usual hardy build-quality on the externals with uprated internals, and a Gate MOSFET as standard to squeeze every drop of performance out of these rifles.  The MOSFET is an X-ASR module from Gate which serves to protect your circuits and batteries.  It also allows basic troubleshooting on the board thanks to status indicator LEDs. The Edge series equally features an ESA™ quick change spring system which dramatically reduces the amount of time to change the output power of your rifle, allowing you to change the main spring via the Buffer Tube. The externals are made from a mix of Aluminum and Zinc Alloy that have undergone a whole series of process to achieve a work-class scratch resistance finish.

The set does not include a battery or a charger.
