An update for the SOCOM guys. From my experience front-to-back, I don't think Colt "approved" the SOCOMs for the rebate exactly. Given the speculation on the serial numbers (maybe there wasn't a definitive range and it was a true parts grab cleanup run), maybe the couldn't add an approval to the 3rd party rebate place based on a specific range. I'm giving everyone the benefit of the doubt, and I'll assume that's the case. Anyway, mine was rejected initially. I pursued it more as I found out through this thread others were getting approved. I got the 3rd party number for the rebate place (1-844-456-2658) and started there. Over three weeks ago, I called to ask about the rejection and explained other SOCOMs were being approved. I got the "let me check, and I'll call you back today or tomorrow" response. I called back at after a week, and was told they were still waiting on a reply from Colt. Going on 3 weeks, I'd heard nothing. So, I used the "need help" email link at the bottom of the rebate place to send the a 2nd inquiry. 2 days later, they replied saying it was still awaiting an answer from Colt. At this point, I reached out to Colt via Facebook. I got an IM from them a couple days later. They looked it up, approved it, and thanked me for the purchase. Shortly after, the customer service rep from the rebate place replied. They basically said that the SOCOMs were still not approved, but that Colt OK'ed my particular request as Customer Satisfaction.
So there you go. That's my experience. My rebate just went to fulfilled, so hopefully it's in the mail, and they can't pull it back after I've put the secret sauce recipe out on ar15.com.
I don't think I took it too far, and I was pleasant. After all, we're the guys dropping $1200.00 on an AR in a down market; I think we should get the freebies.
