Right gents and ladies, finally got a hold of the Crye precision "mag clips". Truly they are inspired. They fit perfectly on steel mags, for Pmags it takes a touch of effort (use a vice) for Tapco; well that is for the truly determined you will need dexterity and a Formica router. Note the pictures, the Tapco is the green one.
