Compact FLEX Gen 2 SMG Platform with HAL ETU Electronics The Specna Arms FLEX Gen 2 SMG series updates the original FLEX concept with improved internal components including the AETHER PRIME reinforced gearbox shell, MAGNUS Hop-Up chamber and PRIME aluminum nozzle. The FX01 SMG delivers a compact, lightweight platform ideal for CQB environments. The HAL ETU provides magnetic Hall-effect trigger sensing, offering improved responsiveness and programmable fire-control behavior. Trigger sensitivity, pre-cocking and fire-mode selections are configured directly through the selector and trigger interface. The nylon fiber reinforced polymer receiver reduces weight while providing structural strength. The polymer M-LOK handguard keeps the front end slim and maneuverable, with a full-length Picatinny rail along the top for mounting optics. The included Light Ops Stock features anti-slip cheek panels and a curved rubber stock foot for stable shouldering. The ESA quick-change spring system enables rapid velocity adjustment without opening the gearbox. Gen 2 upgrades include the AETHER PRIME gearbox shell with reinforced alignment points, the MAGNUS rotating Hop-Up chamber for enhanced consistency and the PRIME aluminum nozzle for improved air seal reliability.
