This is a Magpul ACS-L Adaptable Carbine Stock for AR-15/M4 rifles

Built from impact-resistant polymer and designed to meet Magpul's exacting standards for battle-ready durability and performance, the ACS-L stock innovates on one of Magpul's most popular rifle accessories for improved performance in the field.

The Magpul ACS-L (Adaptable Carbine Stock - Light) is an easy-to-install replacement buttstock for AR15/M16 carbines using mil-spec sized receiver extension tubes. Streamlining the design of the popular ACS, the ACS-L retains the same center storage compartment and sloping cheek weld but removes the battery tubes for a slimmer, lighter weight package.

The larger latching storage compartment to the rear of the stock is ideal for larger storage, including tools, ear protection, or first aid supplies. Rubber butt pad helps mitigate recoil and improve fit and feel.
