Hatsan M27x1 to 1/2 UNF Adapter

Compatible calibers: 4.5 and 5.5 mm

Adapter allowing you to screw a sound moderator with the 1/2x20 UNF standard (like those offered on this site) onto your Hatsan rifle with M27x1 threading. Made using 3D printing, delivered with a protective cap.

Check compatibility

Measure the external diameter of your threading with a ruler: it must correspond to 26.5 mm (± 0.2 mm).

⚠️ Does not fit the Hatsan Bullboss, which already has a silencer with a different threading.

Installation

1. Install the sealing gasket on the adapter.
2. Screw the adapter onto the barrel, without forcing.
3. Attach the silencer without applying excessive pressure (plastic part).

The inside of the adapter allows you to reposition the spring.

FAQ

How do I know if my Hatsan is compatible?

Measure the external diameter of your barrel's threading. If it is 26.5 mm (± 0.2 mm), the adapter is suitable.

Is the sound moderator included?

No, only the adapter is supplied (with a protective cap). It allows you to mount the moderators with the 1/2x20 UNF standard available on this site.

Is it compatible with the Hatsan Bullboss?

No. The Bullboss already has a silencer with a different threading.
