More length, more options

This 50mm outer barrel extension is the simple fix when your airsoft replica needs a little more reach up front. Whether you are clearing a long handguard for a suppressor or just chasing a longer, meaner profile, it screws on in seconds.

Standard 14mm CCW fitment

The extension uses the industry-standard 14mm CCW (anti-clockwise) thread found on the majority of AEG rifles and many gas pistols. Unscrew your existing flash hider or thread protector, spin this on, and your muzzle device goes on the front.

Light in the hand

Machined from aluminium alloy with a clean black finish, it adds length without loading up the muzzle, so your replica stays balanced and quick to handle. The finish blends neatly with most barrels and accessories.

No effect on performance

Because it sits ahead of the muzzle and never touches the inner barrel or hop, it changes nothing about your FPS, range or accuracy. It is purely an external fitment for length and mounting.

Build your setup

Pair it with a suppressor or tracer to finish the look. Browse the rest of our airsoft accessories to complete your build in one order.

Frequently asked questions

What does 14mm CCW mean?

CCW stands for counter-clockwise, the most common negative thread on airsoft rifles and many pistols. The extension has a matching 14mm CCW thread so it screws straight on where your flash hider or suppressor would go.

Why would I want a barrel extension?

It lengthens a short outer barrel so a suppressor or tracer unit clears the front of a handguard, or simply gives a longer, more realistic silhouette. It also lets you reach the correct length for a specific muzzle device.

Will it fit my gun?

It fits any airsoft replica with a 14mm CCW outer barrel thread, which covers the majority of AEG rifles and many GBB pistols. Check your current muzzle device unscrews anti-clockwise to confirm.

Does it affect how the gun shoots?

No. It is an external extension that sits ahead of the muzzle and does not touch the inner barrel or hop unit, so it has no effect on FPS, range or accuracy.

Can I stack a suppressor on the end?

Yes. The extension carries the thread forward so you can mount a 14mm CCW suppressor, tracer unit or flash hider on the front once it is fitted.
