Specna Arms SA-H11 ONE™ M4 Carbine Airsoft Rifle in Black

Specna Arms SA-H11 ONE™ M4 Carbine Airsoft Rifle in Black

If you're after a solid, full-metal airsoft rifle that doesn’t cut corners—something that feels just as good as it performs—the Specna Arms SA-H11 ONE™ M4 Carbine should be right up your alley. Built tough and specced for versatility, this airsoft gun is a battlefield-ready replica that suits both aggressive indoor pushes and long-range support roles outdoors.

This airsoft rifle’s externals are a blend of zinc and aluminum alloy, backed up with steel where it counts—pins, screws, sling swivels—so you don’t have to worry about weak points during rough use. Both the battery stock and pistol grip are polymer, keeping it comfortable and light in the right places. And that finish? Anodized and powder-coated after sandblasting, giving it a gritty, wear-resistant surface that can take its fair share of scrapes and knocks. A proper workhorse.

The SA-H11 shines with its Enter & Convert™ quick spring change system. It's one of those “thank you, finally!” features that saves time and hassle when swapping power levels. The stock M120 spring kicks out around 410 FPS for outdoor dominance. Need to tone it down? The included M90 drops it to a CQB-friendly 310 FPS. No special tools, no tech bench required—just a bit of know-how and a minute or two.

Internally, it’s just as capable. A reinforced gearbox running Version 3 internals with steel washers, 8mm ball bearings, and a steel spring guide gives you the kind of reliability you need game after game. The anti-reversal latches keep everything running smoothly, and the type 2 cylinder works in tandem with the steel circuit breaker for consistent cycling. You also get a polymer rotary hop-up chamber—tight tolerances and easy adjustments make for spot-on BB control, especially useful when switching ammo types or ranges.

Up top, there’s a 22mm RIS rail running the length of the receiver and handguard. Mounting optics? Dead easy. The flip-up iron sights are metal and removable, leaving plenty of room for a red dot or magnifier. The handguard itself has ample room for grips, lights, or lasers. And thanks to the adjustable SF-style stock with a textured buttpad, you can dial in your length of pull to suit your loadout and playstyle—especially handy in fast-paced urban environments.

This airsoft AEG includes ambidextrous controls for the mag release, fire selector, and bolt-catch release, which adds a nice touch of realism and makes it user-friendly for lefties. Plus, the functioning bolt catch isn’t just cosmetic—it adds to the immersion and makes hop-up tuning easier when you're under pressure to get back into the game.

Weighing in at about 3kg, it’s got presence without being unwieldy. The balance is spot on, and once it's slung up or shouldered, it feels lighter than it looks. If you’ve used other high-spec rifles like those from G&P or Classic Army, you’ll feel right at home here. The included 300-round steel hi-cap mag feeds reliably and keeps you in the action longer between reloads.
