Specna Arms SA-X02 EDGE Airsoft Submachine Gun – Black

If you're after a compact, tech-packed submachine gun that’s built for speed, precision, and serious versatility, the Specna Arms SA-X02 EDGE™ in black delivers on all fronts. Designed as part of the EDGE 2.0 series, this airsoft SMG combines rock-solid externals, next-gen internals, and smart electronics to create a replica that's as competitive indoors as it is reliable as a secondary for snipers or support gunners.

The SA-X02 is Specna Arms’ answer to the growing popularity of AR-style SMGs, and it hits the mark beautifully. Built on a compact platform with a PDW-style adjustable stock, it’s tailor-made for tight CQB spaces where agility matters. The slim Strike Industries licensed M-LOK handguard keeps the profile tight while still offering attachment space for lights, lasers, and grips—one of which is included in the box.

Internally, this isn’t just a cut-down rifle—it’s packed with some of the best features Specna Arms has to offer. At the heart of the build is the ORION gearbox, known for its durability and ready-to-tune internals. Inside, you’ll find reinforced steel gears, a polycarbonate piston with full steel teeth, an aluminum sealed nozzle and cylinder head, 8mm ball bearings, and a bearing spring guide. It’s designed to handle M140 springs straight out of the box—serious hardware for serious performance.

Adding to the appeal is the factory-installed ASTER™ MOSFET system from GATE, one of the most respected names in airsoft electronics. This isn’t just a trigger protector—it brings 250 levels of trigger sensitivity adjustment, optical sensors, motor and battery protection, and programmable fire modes using either the trigger or the optional Gate Control Station app. It’s the kind of smart tech that gives you an edge on the field, especially in fast-paced games where milliseconds count.

Specna didn’t stop there—the SA-X02 also features the ESA2™ quick-change spring system. No tools, no disassembly, no drama. Just pop off the stock guide and swap the spring. It comes with a spare M90 spring too, ideal for bringing FPS down for indoor sites without needing a tech bench. The system is even protected by a European patent, showing just how committed Specna Arms is to making tuning easy and field-friendly.

Accuracy is locked in with a 6.03mm precision inner barrel paired with a rotary hop-up chamber and a Helium™ Flat Hop bucking. That combo means tighter groupings, better range, and more stable shots—whether you're suppressing a hallway or picking off enemies from cover.

The rifle’s external build quality is just as good as the internals. The PDW stock keeps things compact, the flip-up iron sights are ready out of the box, and the entire upper receiver is designed to be tough but lightweight. It’s the kind of build that feels premium, performs hard, and is engineered to last.

Two 120-round mid-cap S-MAGs come in the box, each with the distinctive Specna Arms textured finish for better grip and reliable feeding, even at high rates of fire. The SA-X02 is wired to DEANS/T-plug connectors for more efficient power delivery—though you’ll need to pick up a battery and charger separately.

If you’re looking for an airsoft gun that’s smart, fast, and ready for aggressive CQB play—without sacrificing long-term upgrade potential—the SA-X02 EDGE™ deserves a spot in your kit. It’s not just a compact option; it’s a fully-fledged performance platform in a smaller package.
