Thanks guys. The basic problem I had with this claim is that the SPS is just a BDL with a different stock and finish on it. Since the BDL doesn't have the reputation of faulty magazines, I was wondering why the SPS would have it. So far, I haven't heard anyone but this one guy offer any complaints.

I'm starting to wonder if maybe a shipment he recieved had a few faulty ones in it and he had to deal with refunds or exchanges. That seems to be the only plausible explanation I can come up with.
