Thanks Mickey and all.
How is possible to send a photo of my double in this forum?
Previously, I send a mail to "Contac Us" with this cuestón but d'not answer yet.
Both the barrels and the receiver are solid and big, but only the photos wil be speak by self.
My idea is make the reproof in England but, how?
Sorry for my bud English.
Thanks in advance.
