Magpul's ACS-L is a lightweight, drop-in buttstock for AR-15 carbines with mil-spec receiver tubes. Features integrated storage and improved cheek weld in a streamlined design.
Fits: AR-15
The ACS-L represents a refined approach to AR-15 buttstock design. As a purpose-built replacement for standard mil-spec receiver extension tubes, it delivers genuine improvements in ergonomics and practicality without unnecessary complexity.
The ACS-L strips away unnecessary features while retaining the functional advantages that matter in the field. The center storage compartment provides practical utility without adding bulk. The streamlined profile reduces weight and snag points, making it ideal for shooters who value efficiency and responsiveness.
This stock is engineered specifically for AR-15 and M4 carbines equipped with mil-spec diameter receiver extension tubes. Installation requires no gunsmithing—simply swap it onto your existing tube.
Note: Receiver extension tube not included. Verify your rifle uses a mil-spec (1.148-inch diameter) tube before ordering.
