Hunter Airsoft gives his take on the Specna Arms SA-E09 EDGE. The SA-E09 carbine replica has a KEYMOD handguard, short RIS rails, and a standard muzzle device. It features a MOSFET X-ASR module by GATE Electronics, improving safety, trigger reaction, and the lifetime of electronics. The replica has an internal precision barrel and a new type of Hop-Up rotary chamber for accuracy. The ESA Quick Spring Change System allows for rapid power adaptation without special tools.
