Last I heard Ruger had stopped making 20 and 30 round Mini-14/Ranch Rifle magazines altogether (i.e. they are out of production), so the only ones available these days are either used Ruger magazines or aftermarket magazines from other manufacturers. Was this rumour incorrect? It sounded believable to me since the law enforcement .223 rifle market has pretty much gone over exclusively to the AR-15, so with Mini-14 sales to police departments pretty much ended and Ruger's official policy of only selling 20 and 30 rounders to law enforcement, there really wouldn't be any reason for Ruger to keep the 20 and 30 round magazines in production anymore.
