Key Features and Specifications
Electric Blowback System (EBB): The airsoft gun features a strong electric blowback system that simulates bolt movement with each shot, enhancing realism during use. Reviewers note this adds immersion, though the added weight can impact battery life and rate of fire.
Durable Construction: Most external components, including the receiver, barrel, and stock assembly, are made from blackened steel for a realistic look and high durability. The pistol grip, stock, and magazines are high-quality ABS polymer to balance weight.
Internal Build Quality: It is equipped with a robust Version 3 all-metal gearbox featuring steel gears, a polycarbonate piston, 9mm bearings, and a quick-detach spring guide for reliability.
Compact Design: With an adjustable length of approximately 640mm (collapsed) to 720mm (extended) and a weight of around 3.2 kg, it is designed for maneuverability in tight spaces.
Accessory Rails: A 22mm top-mounted RIS rail on the hinged dust cover allows for secure optics mounting.
Magazine Compatibility: It comes with twin mid-cap plastic magazines, each holding approximately 50 rounds. Note that it is not compatible with MP5 magazines.
Battery: The replica is rear-wired with a mini Tamiya connector and is designed for a 7.4v Li-Po battery (sold separately).
