Match grade mags are made to the same exacting tolerances of the high end power mag series. That measn die controlled tolerances held to +/- .001 inches (over 75% tighter tolerances than the out dated military specifications used by their competitors). The spring used in match grade mags are made from the same aerospace grade rocket wire as those used in their high end power mag series. The fixed base plate on match grade mags comes standard with two holes to facilitate the simple installation of the CMC's screw on base pads.
