Mughal,
buddy

- I'm sorry there has been no response to your post (until now). When you first posted I went out and looked for some info. on your rifle.
But waited to allow the 'american audience' (this place) to comment.
Kral, as a company seem to have existed for a fairly short time, they
are known here
in the UK but mostly for Spring Guns.
As you'll know they are a Turkish company but (to me anyway) dont seem very have much of an Internet Sales presence - I couldn't find their own company web page!
But there is a list of 'international vendors' for Kral Airguns, for which I have now lost the WWW link :-( (but it does exist, out there).
Clearly the brand is near unknown in N America and I'm thinking you should consider confining your search to Europe, the 'Middle East' & the Indian sub continent.
Best of luck with your search - some photos of your rifle would be appreciated by all (esp.me).
