Just off the top of my head, for the AR's I have about 12 Thermolds, 8 steel "range mags", maybe 20 USGI 30's NIW for the future, 15 USGI 30's in varying condition for daily use, 10 USGI 20's, 10 Bushy 10-rounders, and 5 Frakenmags for future target practice.
For the M1A maybe 4 10-rounders, 2 Chinese 20's, 15 NIW 20's (busted my bank), and a couple of Thermolds.
For the FAL, something like 40 NIW 20's, 2 20's for current range use, and 4 10-rounders.
Not to mention 40 additional mags for the Glocks and HK Mk.23 and USP's.
Obviously, I went on a shopping spree in 1999. My friends thought I was nuts, but I have mags now and they don't. In fact, the used USGI 30's I bought for $9 early in 1999 they paid $125 each in December 1999. Bans make gun stores rich.
