    The patent-pending Magpul ACS Adaptable Carbine/Storage – Mil-Spec Model is a drop-in replacement butt-stock for AR15/M16 carbines using mil-spec sized receiver extension tubes. A streamlined, anti-snag profile shields the release latch to prevent accidental activation and the extra-power lock mechanism uses a premium chrome-silicon spring to avert auto-collapse failure by resisting spring relaxation. Similar to the Magpul CTR™, the ACS also features a supplemental friction lock system that minimizes wobble* 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.


     • Two water-resistant battery storage tubes located on the left and right sides of the stock  
     • Each tube will store up to three CR123 lithium or two AA batteries
     • Tubes are accessible from the rear via a tethered, hand-removable rubber plug
     • Storage compartment in tail of stock with positive latching access door on right hand side  
     • LOP is adjustable from 11.1 inches to 14.4 inches
