UAC - Hi-Capa Magazine Base Type A (Black) hard kick is basically describes the backSpecification: Material: Aluminium Alloy Description: The UAC Mag Base is the result of our study of all types of mag pad on the market and combined the requirement from our master shooters. It provided a larger surface for holding and allow more room for the magazine to fit into the mag housing while reloading. Checkered surface on the side gives you more friction for a firm grip. Numbers are engraving at the bottom of the pad for idenitifcation.
