I received this 2 weeks ago, but when I went to install it the mounting blocks did not fit the scope. The bar is the right size, but the mounting blocks appear to be for a C8 not a C11. I sent an email and got a single response that it was in the system, but since then I have been unable to contact FarPoint. No one answers the phone and to follow up on the email requires a logon. I registered for a logon, but did not get a response to that to be able to log on.
