I ordered a Tier One FTR Bipod with a pic rail adapter, but I think I got the wrong adapter. Their website has the code T1FTR-QDPIC engraved on the adapter, but the one I received shows T1FTR-012 engraved on it. Can anyone confirm if this is right? I'm trying to get a response from Tier One, but they have been rather slow in responding to my emails.
