These 21 round capacity magazines are constructed from a proprietary polycarbonate formula. Featuring our patented stainless steel internal feed lips, a stainless steel increased power spring and an anti-tilt follower. The translucent design allows for visible round count confirmation from any side. A textured outside surface ensures an intuitive grip for precise manipulations.

*Note: DO NOT use petroleum based cleaners/solvents or lubricants on or in the magazine body. The magazine is made of an Si-PC material. Prolonged exposure will cause the material to degrade and become brittle.
