Magpul's ACS-L (Adaptable Carbine Stock - Light) Mil-Spec is a drop-in alternate buttstock for AR15/M4 carbines using Mil-Spec-sized receiver extension tubes.
A streamlined version of the ACS, the ACS-L operates with the same centre storage compartment and cheek weld; however, the battery tubes have been dropped for a slimmer, lighter-weight package.
Made in the USA.
