Specna Arms SA-H09 ONE™ M4 Carbine Airsoft Rifle – Black

Solid, sleek, and purpose-built for adaptable gameplay, the Specna Arms SA-H09 ONE™ brings together high-grade materials, clever internal features, and ergonomic design into a highly dependable electric rifle. With a realistic M4-style build and included features that rival much more expensive models, this airsoft rifle is ideal for players looking to dominate in both outdoor and indoor scenarios.

Constructed from a mix of zinc and aluminium alloy, with steel reinforcements in critical areas like screws, pins, and sling swivels, the SA-H09 feels rock-solid in hand. The receiver and RIS handguard are anodised and then powder-coated for abrasion and corrosion resistance, giving the rifle a premium matte finish that holds up well against heavy use. The polymer SF stock and pistol grip are comfortable and durable, and the whole platform feels remarkably well-balanced, especially when slung or shouldered.

This model features the excellent Enter & Convert™ quick spring change system—allowing for spring swaps in seconds once the gearbox is removed. You’ll start with a powerful ~410 FPS, perfect for mid- to long-range outdoor play. If your site has tighter limits or you’re heading into CQB, simply swap in the included M90 spring to drop it down to around 310 FPS. It’s quick, easy, and doesn’t require a workshop’s worth of tools.

The internal gearbox is reinforced at the cylinder head and comes equipped with 8mm ball bearings, steel gears on spacers, and a steel spring guide—ideal for long-term reliability. Anti-reversal latches and a type 2 cylinder help keep the cycling smooth, and it all adds up to a system that’s ready to handle heavy use straight out of the box. The polymer rotary hop-up unit gives you precise BB control, helping to push the 360mm inner barrel’s range and accuracy to impressive levels.

On top, the SA-H09 offers a full-length 22mm RIS rail running along the upper receiver and handguard, giving you ample room for optics, PEQ boxes, or other accessories. Included flip-up iron sights can be easily detached to clear the way for your preferred aiming system. The adjustable SF-style stock includes an anti-slip pad and allows for custom length adjustment to match your gear and body type. A 14mm CCW threaded flash hider rounds things off, ready for tracer units or suppressors.

To boost realism, the SA-H09 also includes a working bolt catch that holds back the dummy bolt cover—ideal for quick hop-up adjustments and a nice immersive touch. The rifle feeds from a 300-round Hi-Cap magazine included in the box, and is compatible with most standard M4/M16 style mags from other brands.

At 3350g, this airsoft rifle has a weighty, authentic feel without becoming unwieldy, and its 840–930mm adjustable length keeps it agile whether you’re going prone, clearing corners, or sprinting between cover. While it doesn’t include a battery or charger, it’s wired for mini Tamiya and fully compatible with LiPo or LiFe batteries.

If you're looking for a durable and well-balanced rifle that’s powerful, customisable, and ready to be your primary in a variety of airsoft environments, the SA-H09 ONE™ ticks all the right boxes.
