Made to the same exacting standards as CMMG’s other AR15 pattern magazines, the CMMG 30rd 5.56mm FDE magazine stands up to the elements with its advanced polymer construction and makes use of its uniquely CMMG style to enhance grip traction in adverse conditions. The red anti-tilt follower provides a positive visual indicator when your mag runs dry and ensures smooth feeding. Raised dot stippling and 360 degree re-enforcement bands guarantee you’ve got a grip when swapping magazines.
