PMR 30
$500.00
(They are so rare, I doubt the seller would take that amount.)
They were going for about $1K post-Sandy Hook, but the hysteria is finally dying down...you can get them for about $650 on Gunbroker (still too high, IMHO).
Of course, there's no point in my wanting one, now that Colorado bans magazines over 15 round. Grrrr.
