I'll spare everyone my own hard luck story, but I managed to get two non-listed AR lowers for "normal" prices.
Crying about it on a forum ain't gonna get you one, making phone calls, doing the legwork, driving to the FFL etc. that'll get you a ticket to AR land. Seriously, buying a stripped non-listed AR lower is one of life's lesser exspenses.
Heck, you could make a phone call to Clint at
www.carricozarmory.com/lowers.htm right this very second and have him overnight a lower to your FFL to DROS tommorow. That is if someone that wanted it more than you didn't already do just that and clean him out.
Now, buck up and score that lower!
P.S. It could very well be too late to do it the way described above, I suggest going to:
www.calguns.net/calgunforum/forumdisplay.php?f=81and buying it from a stocking dealer, maybe you'll pay twice what it's worth dollar wise, but you're buying peace of mind and eternal AR joy.
Or, there's alway's the FAB-10.
Good luck.
