The MOE carbine stock, mil spec model (Magpul Original Equipment) is a drop-in replacement buttstock for AR15/M16 carbines using mil spec sized receiver extension tubes. Designed for light, fast action the streamlined A-frame profile avoids snagging and shields the release latch to prevent accidental activation. The mil spec model includes a standard 0.3 in thick rubber butt pad which provides positive shoulder purchase to prevent slippage even with body armor or modular gear.
