This magazine is the latest in magazine development. Made out of a very lightweight polymer modeled into a “Waffle” pattern makes for a very strong magazine that won't dent or rust. Only recently have these magazines entered the United States. They can be found in a variety of colors and different waffle type patterns, including the less common poly smooth side pattern with a waffle rib that runs down the back of the magazine. Expect to pay a higher prices for these magazines.
