Called DSA, and ended up ordering three: two for me, and one for a friend of mine since his debit card had it's number stolen, and a new one was enroute...
By the time he gets it, these receivers will likely be sold out.
And the price on them is VERY reasonable.
So anyway, I call DSA, I get forwarded over to the sales department, and the salesperson had no idea that Type III receivers were available. We argued about it for a moment (I started reading the FAL Files forum post), then another lady overheard the conversation and advised her that yes, they were making a limited run of Type III's.
Once that situation was resolved, the order process went very smoothly. The FFL I wanted to transfer them to was even already on file, which made things MUCH easier.
As I was completing the order, I heard the other salesperson selling four Type III's to another customer, so these are going fast, folks.
Thanks DSA for offering these again. Now I've got the two correct receivers for my eventual pair of Para FAL's (one 16", and one 18").
