The Magpul CTR carbine stock in Flat Dark Earth (brand part no. MAG310-FDE) is a collapsible Compact/Type Restricted buttstock, made in the USA as a drop-in replacement for AR-15, M16 and M4 carbines. It fits mil-spec receiver extension tubes only, and the stock ships without a tube, so confirm you already have a mil-spec tube on hand. Magpul gives it a streamlined A-frame profile that avoids snagging on gear and shields the ambidextrous release latch from accidental activation. A supplemental friction lock system takes the wobble out of the stock on the tube, and an ambidextrous push-button QD mount takes sling swivels up to 1.5 inches. The Flat Dark Earth finish matches tan and coyote builds.
