Description
Specification

A tighter seal, a better shot

The Specna Arms Aluminium Nozzle (SPE-08-023676) is an O-ring equipped air nozzle that upgrades the heart of your AEG’s air system. The O-ring forms a tighter seal against the cylinder head, improving air efficiency, shot consistency and trigger response over a plain or worn nozzle.

Correct length, reliable feeding

Machined to 21.4mm, it matches Specna Arms EDGE and standard M4 / M16 Version 2 builds, so BBs chamber cleanly for smooth semi and full-auto fire. Getting nozzle length right is one of the simplest ways to cure feeding and sealing issues.

Built to last

The aluminium construction, finished in anodised blue, resists wear far better than plastic. At around 2g it keeps cycling light while holding its shape shot after shot, making it a dependable long-term part.

Fit it right

This is an internal upgrade that suits a routine gearbox service. If you would rather have it fitted and tuned, our airsoft repair service in Kent can help, and you can find matching spares in our airsoft accessories.

Frequently asked questions

What length is this nozzle?

It measures 21.4mm, the correct length for Specna Arms EDGE and most standard M4 / M16 Version 2 builds. Always match nozzle length to your platform for reliable feeding.

Why does the O-ring matter?

The O-ring creates a tighter air seal between the nozzle and cylinder head, which improves consistency, air efficiency and trigger response compared with a plain nozzle.

Will it fit non-Specna M4s?

It is designed around Specna Arms EDGE and TM-spec Version 2 M4 / M16 gearboxes. Many TM-clone M4s share this 21.4mm spec, but check your existing nozzle length before ordering.

Is aluminium better than a plastic nozzle?

Aluminium is more durable and holds its shape under repeated cycling, which helps maintain a consistent seal and feed over a long service life.

Do I need to be 18 or hold UKARA?

No. This is an internal spare part, so there is no age restriction and no UKARA requirement to buy it.
