Specna Arms SA-C28 CORE™ HAL ETU™ Gen.2 Grey

Specna Arms SA-C28 CORE Gen.2 is an electric carbine replica developed in collaboration with the American brand EMG Arms and officially licensed by Daniel Defense®. The model is built on the CORE Gen.2 platform, designed to provide players with the best possible experience at an affordable price, with superior performance straight out of the box and improved internal components for durability and consistency in the field.

Performance and Internal Systems

CORE Gen.2 replicas come factory-equipped with advanced technical solutions that enhance accuracy, trigger response, and reliability. The SA-C28 includes:

• TDC Magnus™ hop-up chamber (Top Down Center), European patent, allowing for very precise and stable adjustments.

• Helium™ Flat Hop Eraser, which stabilizes the BB's trajectory by applying a uniform underhop effect.

• Sealed aluminum nozzle, ensuring constant compression.

• Æther™ gearbox (reinforced frame, precocking, AoE window, spring release function, alignment holes, and compatibility up to M140 springs).

HAL™ ETU Gen.2

The replica is equipped with the HAL™ electronic unit, compatible with brushless motors, offering:

• magnetic sensor trigger detection (Hall)

• active brake

• adjustable trigger sensitivity (5 levels)

• adjustable precocking (6 levels)

• programmable AUTO fire modes (full auto, 3-burst, 5-burst)

• programmable SEMI fire modes (semi, binary, AUG, sniper)

• easy programming from the trigger

• low battery warning

Construction, Ergonomics, and Materials

The body of the replica, stock, and pistol grip are made from fiber-reinforced polymer for high strength and low weight. Metal elements include the outer barrel, 12.5" RIS front, flash suppressor, trigger, and sling attachment points.

The construction is precise, with no play between the upper and lower, and the use of reinforced polymer reduces overall weight, making the replica ideal for long gaming sessions or dynamic play styles.

ESA™ System – Quick Spring Change

Specna Arms has integrated the ESA™ system, which allows for changing the main spring without disassembling the gearbox. In just a few steps and without special tools, the user can adjust the replica's velocity according to field rules or personal preferences.

An additional M90 spring is included in the package, allowing the replica to be configured directly for CQB or open field.
