Extender | M18x1 | AEA S45 | DonnyFL – Barrel thread extension adapter

This barrel extender is a thread extension adapter designed for the AEA S45 air rifle. It extends the M18x1 thread forward by 5cm, creating additional clearance for mounting suppressors or other muzzle accessories. The adapter features aluminium construction with a black finish.

Construction and materials

The extender measures 5cm in length and is manufactured from aluminium with a durable black anodised finish. Both ends feature M18x1 threading with CW (clockwise) orientation. The lightweight aluminium construction adds minimal weight to your rifle setup while maintaining structural integrity.

Application and use

This extender serves recreational shooters who need to reposition their muzzle accessories forward on the AEA S45 platform. It's particularly useful when the existing barrel thread sits too far recessed, preventing proper accessory mounting. The adapter also creates a visually extended barrel profile for aesthetic purposes.

Integration and compatibility

Specifically engineered for the AEA S45 air rifle, this extender features 18mm CW threading on the muzzle end. The M18x1 thread pitch ensures compatibility with standard airgun suppressors and muzzle devices. Installation requires simple threading onto the existing barrel thread.

Maintenance and lifecycle

The anodised aluminium construction requires minimal maintenance. Periodic inspection of thread integrity is recommended, especially after frequent accessory changes. Clean threads with a soft brush to prevent cross-threading during installation.
