A FFL friend of mine has them for sale.
He's got 2, and he's asking $150 each.
Wanna play, gotta pay.
IM me if youa re interested, and I'll get you his contact info.
I have a KKF built 22 upper on a BM V-Match Flat Top with a heavy Douglas 11.5 barrel, Ciener M16 conversion with 10 30rd mags. I get a lot of e-mails from people who just want to buy the mags. After reading the above posts I know now why everyone wants the 30 rd mags.
