The Magpul CTR Carbine Stock - Mil-Spec is a collapsible replacement stock for AR-pattern carbines equipped with a Mil-Spec sized carbine receiver extension tube. This exact version comes in Magpul's Modified Coyote Brown color, a darker coyote shade suited to coordinated rifle builds and mixed earth-tone configurations. Its streamlined A-frame profile keeps the stock compact and helps prevent it from catching on clothing, slings, body armor, or other equipment during handling. The ambidextrous release latch is shielded within the stock body to reduce the chance of an unintended adjustment while remaining readily accessible from either side. Once the desired length of pull is selected, the supplemental friction lock helps limit movement between the stock and a properly sized receiver extension, creating a steadier and more consistent shoulder interface. A sloping cheek surface provides practical contact without adding unnecessary width or bulk. Multiple sling arrangements are supported through an integral ambidextrous push-button QD socket, rear and bottom sling loops, and a toe lanyard opening. The removable 0.3-inch rubber butt-pad supplies a non-slip shoulder surface and remains useful when the stock is placed against body armor or load-bearing gear. This CTR also accepts compatible snap-on Magpul cheek risers when the host firearm and charging-handle arrangement permit their use. The stock measures up to 7.0 inches long, 5.2 inches high, and 1.7 inches wide, with an unloaded product weight of 8.9 ounces. On a standard M4 configuration, it provides an approximate 10.3-inch collapsed length of pull, a 13.6-inch extended length of pull, and 3.3 inches of adjustment. The receiver extension tube is not included, and this Mil-Spec model should not be installed on a Commercial-Spec tube. Made and engineered in the USA, it provides a practical combination of adjustability, sling versatility, positive shoulder contact, and reduced stock movement for compatible carbine builds.Specifications and Features: Modified Coyote Brown (MCB) finish Fits Mil-Spec sized carbine receiver extension tubes Compatible with AR15/M4 and AR10/SR25/M110 platforms Streamlined snag-resistant A-frame profile Ambidextrous shielded release latch Supplemental friction lock helps reduce stock movement Integral ambidextrous push-button QD sling mount 1.25-inch sling loops and toe lanyard hole Removable 0.3-inch anti-slip rubber butt-pad Maximum dimensions: 7.0 L x 5.2 H x 1.7 W inches Product weight: 8.9 oz Made and engineered in the USA Brand: Magpul Series: CTR Product Type: Collapsible Carbine Stock Manufacturer Part Number: MAG310-MCB UPC: 840815150831
