Magpul ACS-L Carbine AR-15 Stock Mil-Spec

Features

  • Streamlined Lightweight Design: Slimmer, lighter version of the ACS® series by removing battery tubes while retaining center storage and cheek weld.
  • Integral Storage Compartment: Positive-latching access door on right side houses small items (battery tubes removed for weight savings).
  • Sloping Cheek Weld: Provides a wide, consistent contact surface for improved comfort and repeatability.
  • Supplemental Friction Lock: Chrome-silicon lock spring minimizes play and wobble along entire length of pull.
  • Shielded Release Latch: Prevents snagging and accidental operation in confined environments.
  • Anti-Slip Rubber Butt-Pad: Replaceable 0.30″-thick pad offers traction and impact protection.
  • Multiple Sling Mounts:
    • Mid: Includes reversible Type-3 sling mount for up to 1.5″ push-button swivels (swivel not included).
    • Rear/Bottom: Integrated 1.00″ loop for traditional sling attachments.
  • Made in the USA: Precision-molded and assembled under Magpul’s stringent quality standards.
