AR-15 ACS-L Stock Assy Collapsible Mil-Spec. The Adaptable Carbine Stock-Light (ACS-L) is a slimmed-down, lightweight version of Magpul's ACS stock. It provides maneuverability by eliminating the ACS side storage compartments while retaining a wide cheekweld and a storage compartment in the tail. The stock includes a friction locking system to minimize wobble when extended and a reversible socket for QD sling swivels with a 1" sling loop molded in the toe. The ACS-L Buttstock Kit includes Mil-Spec buffer tube, Carbine buffer, Chrome Silicone recoil spring, Receiver end plate, and Receiver extension castle nut. Available colors include Black, Dark Earth, and OD Green.
