[Gin&Tonic]

I'm looking for a mount with a 20moa or so cant. Bassett apparrently has cant but I am unable to contact them.(doesn't return emails and doesnt answer the phone...must be a busy guy or doesn't want anymore money lol). Does anyone have any experience with the CASM mount? Durable?...holds zero?
Thanks in advance.
