Handguard

[Aktarus]

Hi boys, my name is Walter and I live in Italy. I can not buy components in the United States, but I can buy in the Czech Republic
I want to buy the andguar of TROY on which I would put a RED DOT.
I like it very much because he is Co witnes, but I read that it maintains a stable and non-zero. Can you tell me if it is true?   
I looked at these handguard http://kinggun.jansladky.cz/Modernizace-Sa-vz-58/ seem solid and well made. The fixing is like the military and should not cause stability problems but it is too big and is not co witness. :-(

What advice can you give me?

P.S. I no speack english

For US customers kinggun can not send it out of EU but you can get the same hand guard from corwin-arms in Canada or Zahal from Isreal
