Hey SDS, I was wondering about the part interchangeability of the Duo-Sys shotgun. Can you tell me what is compatible with the Benelli M3?

I've read the stocks are interchangeable with the Rem 870. Can you confirm this?

Looks like you guys are no longer importing this one?

Also curious as to how durable you guys consider this one, in your experience? Or any other info you might want to add.

Thanks.
