Cool story here, brother. When I ordered my 12" for my Mod 1, I waited a week, and called. Just wanted to know what the availability was, curious, you know? The guy told me that the 12"s were OOS, and the next production run was going to start in 3 weeks... then he says, "Can you hold for a few minutes?" Or course I can, my good man. He gets back on the line as says, "I can take a 12" rail from the guys that are assembling the full guns, and ship it out to you today." I says, No need to do that, my good man - don't rob a guy that's waiting on a full gun... He says, "They're building for stock right now, and all their guns aren't sold. But your rail is sold, so I'll send you one today..." I thanked him graciously, and accepted his offer.
Moral of the story - that's why it pays to talk to humans on a phone, and not send emails.
