So The mag ban has done a wonderful job of curbing the rampant crime the state of Colorado has. My question is..... Can 10 round magazines for a .458 socom in an AR platform be legally purchased in this state now? They look an awful lot like 30 round 5.56 magazines but only hold 10 .458 socom rounds. If the mag is stamped 5.56 you couldn't buy it. An unmarked mag tho?
