The Magpul ACS-L (Adaptable Carbine Stock - Light) is a drop-in replacement buttstock for AR15/M16 carbines using mil-spec sized receiver extension tubes. This is the full kit. It consists of the stock body, extension tube, buffer, spring, castle nut, and receiver plate. A streamlined version of the ACS, the ACS-L utilizes the same center storage compartment and cheek weld but removes the battery tubes for a slimmer, lighter weight package. Made in U.S.A.
