An HK416 carbine that punches above its price

The Specna Arms SA-H09 ONE is an HK416-style carbine built for players who want a realistic, full-metal replica without stepping up to a tech-heavy EDGE build. It looks the part, handles like the real steel it is modelled on and arrives skirmish-ready in a UK site-legal configuration.

A gearbox built to be tuned

Inside is a reinforced Version 2 gearbox running steel gears and 8mm bearings. The standout feature is the Quick Spring Change (Enter and Convert) system, which lets you change the spring from the rear of the gearbox to adjust FPS for different site limits, no full strip required. It ships around 310 FPS on the supplied M90 spring, measured on 0.20g BBs.

Ready for your optics and attachments

The M-LOK front handguard and 22mm top RIS rail give you a genuinely modular platform. Add a red dot, a light or laser, an angled grip and a QD sling mount to build the carbine around your play style. The 14mm CCW muzzle thread accepts most tracer units and mock suppressors.

Power it correctly

The SA-H09 uses a Small Tamiya connector and runs happily on LiPo or LiFe packs. Pair it with a 7.4v LiPo and a quality smart charger for reliable trigger response. Grab batteries and BBs from our BBs, gas and batteries range.

Backed by a Kent workshop

Established in 2006, Platoon Stores runs an in-house repair and servicing bench, so if you ever want a spring swap, an upgrade or a service, we can do it locally. See our airsoft repair service. Remember this is a RIF and a valid VCRA defence such as UKARA is required before dispatch.

Frequently asked questions

Do I need a UKARA registration to buy this?

This is a realistic imitation firearm (RIF), so under the VCRA you must have a valid defence to buy it, such as UKARA registration, being a genuine re-enactor or holding a relevant film or theatre defence. We must verify your defence before we can dispatch a RIF. If you cannot meet a defence, look at our two-tone options instead.

What FPS does it shoot and is it site legal?

The ONE series leaves the factory around 410 FPS on the stock spring, and Specna include an M90 spring giving roughly 310 FPS on 0.20g BBs. That sits comfortably inside typical UK AEG site limits. Always chronograph on the day, as site rules vary.

What battery and charger do I need?

The SA-H09 uses a Small Tamiya connector and is LiPo and LiFe ready. A 7.4v LiPo is the popular choice for a snappy trigger. Batteries are not included, so add a battery, a suitable smart charger and a BB brand from our range.

How easy is it to upgrade the FPS or spring?

Very easy for this class. The Quick Spring Change (Enter and Convert) system lets you swap the spring from the rear of the gearbox without a full teardown, so tuning power for different sites is quick. Our Kent workshop can also do it for you.

Can I fit my own optics, sling and accessories?

Yes. The 22mm top RIS rail takes red dots, magnifiers and scopes, while the M-LOK handguard accepts M-LOK rail sections, grips, sling mounts and lights. The 14mm CCW barrel thread accepts most tracer units and mock suppressors.
