Specna Arms SA-C10 M4 PDW CORE™ Airsoft Rifle in Black

Specna Arms SA-C10 M4 PDW CORE™ Airsoft Rifle – Black

Compact, rugged, and ready to rip through CQB environments like a knife through butter—the Specna Arms SA-C10 M4 PDW CORE™ is a proper workhorse of an airsoft rifle, built for players who need solid performance without weighing themselves down. Whether you're breaking corners in tight urban layouts or dashing across woodland terrain, this little beast handles like a dream.

Let’s talk externals first. The SA-C10 rocks a nylon-fibre-reinforced polymer receiver, stock pad, and pistol grip—keeping things light without feeling cheap in the slightest. It’s that sweet spot where durability meets comfort. Everything else that matters? Solid metal. We’re talking about the outer barrel, RIS handguard, charging handle, flash hider, sling swivels, and even the mock bolt carrier. This mix keeps weight down while maintaining serious toughness where it counts. And no rattling—those receivers are tight as you like. No slop, no wiggle, just a snug, confident fit all round.

Now, here’s where it gets clever—the ESA™ Quick Spring Change System. Need to tweak your FPS for indoor play or switch things up for outdoor games? No stress. Pop off the stock slide and you're in. No gearbox surgery, no need for a tech bench. It’s a lifesaver for folks jumping between sites with varying rules or just wanting to fine-tune their setup without faff.

Out of the box, this Airsoft AEG is pushing a consistent 330 FPS, thanks to the factory-installed spring. But Specna Arms include an M90 spring too, which brings you down to around 270 FPS—perfect for close-quarters play. Smooth, thoughtful touches like that are what make this airsoft rifle shine for both newcomers and seasoned vets.

Under the hood, the SA-C10 packs a Version 2 gearbox with 8mm slide bearings and properly shimmed steel gears. The polycarbonate piston features a full steel tooth rack, boosting durability big time—no stripping under stress here. Add in a Type 0 cylinder, rotary Hop-Up unit, and a 6.03mm precision barrel, and you’ve got a platform that’s seriously accurate for its size. That Hop-Up unit is particularly sweet—clicky, easy to dial in, and it actually holds its setting. Ever had that perfect shot lined up, then your BBs started veering off mid-game? Yeah, this helps.

The PDW-style metal stock is a real highlight. It’s got that no-nonsense, industrial look, but it’s functional too—adjustable length, anti-slip texture, and it doubles as your battery compartment. The battery slots into the buffer tube (LiPo-sized: 12x17x75mm), which keeps everything tidy and compact. Handy if you’re running a tight loadout and don’t fancy bulky external packs.

Top rail and RIS handguard? Check. Plenty of room for red dots, lights, or whatever accessories you fancy bolting on. The rear flip-up sight works well on its own or as backup to an optic. The 14mm CCW thread means you can screw on a tracer unit or suppressor with no hassle. Customisation is easy, and the platform takes to upgrades like a duck to water.

Bottom line? The Specna Arms SA-C10 is one of those rare finds that delivers solid gearbox internals, modular design, and real field practicality without breaking the bank. If you’re after a blacked-out, mean-looking PDW Airsoft AEG that punches above its weight, this one deserves a spot in your arsenal.
