Magpul ACS Carbine Stock Mil-Spec

Features

  • Adjustable Length-of-Pull: Tool-less, six-position adjustment from 11.60″ to 14.90″ to fit a wide range of shooters and shooting positions.
  • Supplemental Friction Lock: Chrome-silicon spring-loaded lock spring minimizes play and rattle along the entire length of pull.
  • Anti-Slip Rubber Butt-Pad: Replaceable 0.30″-thick overmolded rubber pad improves shoulder purchase and recoil mitigation.
  • Integral Storage Compartment: Positive-latching access door on right side houses small items; dual, water-resistant battery tubes on left and right for up to three CR123 or two AA each.
  • Shielded Release Latch: Low-profile lever prevents snagging and accidental deployment in confined environments.
  • Multiple Sling Mount Options:
    • Mid-Stock: Type-3 steel QD socket for up to 1.5″ push-button swivels (swivel not included).
    • Rear: 1.00″ polymer loop for traditional sling attachments.
  • Drop-In Installation: Fits any Mil-Spec (1.14″ OD) carbine receiver extension—no gunsmithing required.
  • Made in the USA: Engineered, molded, and assembled under Magpul’s exacting quality standards.
