Living in the gun-friendly state of NY we are limited to 10 rd capacity magazines unless they are pre-ban. Anyone know if there is a pre-ban 20rd magazine that will work in the OBR?
Unless you can find some old KAC pre-ban SR-25 or really old AR-10 waffle mags, you're not likely to find a legal 20 round mag in NYS that fits that pattern.
Those are available in NYS and that's the largest magazines that can be shipped into this state. Any mag made after Sept 13th 1994 that holds more than 10 rounds is banned here.
Keep a watchful eye out here, on BARFCOM and similar sites for pre-ban SR-25/old AR-10 waffle mags. Several waffle mags sold not long ago on BARFCOM for $50/mag which I thought was a STEAL for anyone behind enemy lines (such as yourself).
