Magpul
Magpul Industries Corporation is an American designer and manufacturer of polymer and composite high-tech firearms accessories.
Founded in 1999 with the intent of developing a simple device to aid in the manipulation of rifle magazines while reloading under stress.
Magpul Industries takes its name from its first product, an accessory for US and NATO armed forces STANAG magazines that aided users in pulling the magazine out of its pouch, hence "Magpul"
