Remember: years before Ruger finally decided to sell larger mags for the Mini 14 (After the '08 election) and then 30 on the US commercial market,
Not true. I bought a Mini-14 in 1983 and two 30 round magazines. All were stock items at the gun shop I traded with at that time. Ruger discontinued the sale of 30 round magazines to all but LEO use after the infamous Bill Ruger "large capacity magazine" letter ....1988(?) as a corporate statement supporting his belief that civilians didn't need high capacity magazines.
