Magpul ACS Carbine Stock Mil-Spec is an adjustable carbine stock designed to enhance stability, ergonomics, and storage on AR-platform rifles. It provides a solid cheek weld and improved control for both range and field use.
The Magpul ACS Carbine Stock Mil-Spec is a drop-in replacement designed for AR15, M4, and similar platforms using mil-spec carbine receiver extension tubes. Built from high-strength reinforced polymer, it offers durability while maintaining a balanced weight for extended use. The stock features a friction lock system that reduces unwanted movement between the stock and buffer tube, improving overall stability and shot consistency. Its sloping cheek weld provides a wide and comfortable contact surface, while the rubber buttpad enhances shoulder grip and recoil management. Dual water-resistant battery storage tubes and an additional internal storage compartment allow users to carry essential gear directly within the stock. A shielded release latch prevents accidental activation, and integrated sling mounting options support various carry configurations. Available in Black and Flat Dark Earth (FDE), it is a practical upgrade for shooters seeking improved control, modularity, and onboard storage.
