Specna Arms SA-C12 CORE™ M4 Airsoft Rifle in Black with PDW Stock

The Specna Arms SA-C12 CORE™ is the definition of compact firepower, engineered for CQB dominance and designed to offer serious performance at an entry-level price point. Whether you’re just getting into airsoft or looking for a lightweight, no-nonsense rifle for close-quarters engagements, this AEG delivers solid internals, rugged externals, and user-friendly features in a sleek, PDW-style package.

Externally, this rifle features a reinforced polymer receiver with a nylon fibre blend—striking an excellent balance between lightweight handling and structural strength. Unlike some budget options that suffer from loose fits, the SA-C12 boasts tight tolerances between the upper and lower receiver, giving the rifle a more premium, solid feel in hand. The metal outer barrel, flash hider, KeyMod rail system, and buffer tube further reinforce the durability of this compact beast.

The 7-inch KeyMod alloy handguard is fitted with removable 20mm RIS / RAS rail panels, allowing you to mount accessories like grips, lights, or lasers exactly where you need them. Up top, you’ll find a 13-inch continuous 22mm RIS rail perfect for optics, complete with removable flip-up iron sights that lock into place. The PDW-style adjustable stock is perfect for CQB manoeuvres and features QD sling mounting points for ambidextrous use and quick transitions.

Internally, the rifle features Specna Arms’ ESA™ (Easy Spring Access) quick-change system, allowing you to adjust FPS in a matter of minutes. The factory spring clocks in around 380 FPS, ideal for mid-range outdoor play, but an M90 spring is included to lower output to ~310 FPS—perfect for indoor or short-range scenarios. No tools, no disassembly—just quick, on-the-fly tuning.

The V2 gearbox is reinforced with a steel gear set, full steel piston teeth, and 8mm slide bearings for smooth cycling and long-term reliability. A polycarbonate piston and full steel tappet plate keep things durable even under high rates of fire. It’s built to handle M140 springs, so if you ever want to upgrade the internals, the base is more than up to the task.

Specna has paired this with a 6.03mm tightbore inner barrel and a rotary-style hop-up unit—giving you the kind of range and accuracy you’d expect from rifles well above this price bracket. For best results, always pair with high-quality BBs to maximise precision and performance.

Included in the box is a 380-round S-MAG Hi-Cap magazine with a textured polymer body. Designed specifically by Specna Arms, this magazine feeds reliably even during high ROF sessions. The rifle is compatible with most standard M4/M16 magazines, giving you flexibility when building out your loadout.

From its rugged, no-rattle build to its tool-less spring change system and compact design, the SA-C12 CORE™ is a CQB-ready electric rifle that offers serious value and real performance—perfect for new players or experienced skirmishers who want a nimble backup or primary for tight spaces.
