Zoraki HP01-02 Converting 5.5mm caliber to 4.5mm

Yes you can. Very easy to do. Here’s where you get the barrel

.177 Zoraki Barrel

Remember when you’re removing the barrel loosen the set screw, underneath the muzzle, that holds the barrel in place. Then unscrew those 2 little screws holding the end of the barrel.
I live in Turkey and the seller does not ship to Turkey where else can I buy ?

A bit late, but the Zoraki is made in Turkey, I would try contacting the maker.

I was fortunate to be stationed in Izmir for two years with the USAF, back in 1972-74, Got to take my new wife and we had a fantastic two years seeing a lot of the ancient sites there. Ephuses, Pammukkale , the Mediterranean down near Adana, and of course Istanbul. We camped on a lot of beaches along the Agean also, never felt safer than when there. Boar hunting back in the mountains, then doves near the granaries near Izmir in the fall.
 
A bit later ... :).

Thanks for the conversion instructions and link to .177 barrel. I just ordered .177 Zoraki Barrel. It was $46 USD shipped.

My Zoraki HP 01-2 Ultra .22 Cal Black should arrive next month from MaxArmory. I chose the .22 as I knew I could also get a .177 barrel. It'll be nice to have the option to switch between the two calibers.
 
Just a follow up from my previous post..... I cancelled my order for the ,177 Zoraki Barrel. This barrel is for the Zoraki HP 01-2. It is not for the newer longer Ultra 10.2" barrel.

The OP was asking about a barrel for his Zoraki HP 01-2 which is a 7-7/8" barrel. Ultra was not even mentioned in this thread until I posted :(.

Fortunately, I was able to cancel my order before shipment. I also asked https://twchambers.co.uk/ if they had the longer 10.2" barrel for the Ultra. They said: "We have no plans to supply any parts for the ‘Ultra’ model.".

In summary:

- Zoraki HP 01-2 (7-7/8" barrel): .177 Zoraki Barrel.

- Zoraki HP 01-2 Ultra (10.2" barrel): Not available at https://twchambers.co.uk/
