Equipped with a Supplemental Friction Lock System for Enhanced Stability and Accuracy – One of the Best Cheek Welds of the Collapsible Stocks on the Market

The patented Magpul ACS (Adaptable Carbine/Storage) – Mil-Spec Model is a drop-in replacement buttstock for AR15/M16 carbines using mil-spec sized receiver extension tubes. A streamlined, anti-snag profile shields the release latch to prevent accidental activation. Similar to the Magpul CTR®, the ACS also features a supplemental friction lock system that minimizes excessive stock movement for enhanced weapon stability and accuracy*. Dual, rear accessible, water-resistant battery storage tubes and an integral storage compartment in the butt of the stock provides multiple storage options. The ACS comes standard with a 0.30″ thick rubber butt-pad which provides positive shoulder purchase to prevent slippage even with body armor or modular gear.

Made in U.S.A.
