Magpul AR-15 ACS Collapsible Mil-Spec Stock Assembly, ODG

Adaptable Carbine/Storage (ACS) stock is a drop-in replacement for standard USGI M4 collapsible stock that gives the tactical operator extra storage options, a secure cheekweld, and an advanced dual-locking lever. Smooth, streamlined exterior contours prevent snagging on clothing, sling, or vegetation, and help ensure fast exits from vehicles without snagging on gear. Removable battery storage compartments run the full length of the extra-wide comb and hold 2 AA or 3 CR-123 batteries, and provide a wide, contoured area for an exceptionally solid cheekweld. Secure molded rubber caps keep water and dust out of compartments and face the rear of the stock for easy removal. Magpul’s dual locking system protects the release lever while allowing length of pull adjustment. The toe has a slot for a 1¼" sling. Also includes the ASC Buttstock Kit: Mil-Spec buffer tube, Carbine buffer, Chrome Silicone recoil spring, Receiver end plate, Receiver extension castle nut.
