Specna Arms EDGE 2.0 Rock River Arms SA-E03 M4 AEG Rifle – Licensed AR-15-Style Electric Carbine

Engineered for serious performance and realism, the Specna Arms EDGE 2.0 SA-E03 delivers next-level craftsmanship and battlefield dominance. Fully licensed by Rock River Arms, this M4-style AEG rifle combines a rugged metal build with cutting-edge internals, ready to perform right out of the box. The full-metal receiver features deep-engraved RRA trademarks and a durable Nano Coating to resist wear over time, giving this rifle both authentic looks and long-term resilience.

The SA-E03 features a quad-rail RIS handguard that’s perfect for mounting your favorite mission-ready accessories. Internally, it’s a beast — built around Specna Arms' ORION gearbox with 8mm steel bearings, a steel gear set, and a powerful 22TPA high-torque motor. A built-in GATE ASTER MOSFET lets you fine-tune your trigger response and fire control, while a rotary hop-up chamber and 6.03mm precision barrel deliver impressive accuracy. The included Helium™ Flat Hop bucking adds consistency for every shot.

One of its standout features is the ESA2™ quick-change spring system — letting you adapt your FPS on the fly without tools. Whether you're playing indoor CQB or outdoor field games, this rifle adjusts to your needs with ease. Out of the box, you also get two durable S-MAG mid-cap magazines and an additional M90 spring, making it a complete loadout for any airsofter looking for power, precision, and reliability.
