Magpul ACS Carbine Stock-Mil-Spec Black

The Magpul ACS (Adaptable Carbine/Storage) – Mil-Spec model is a drop-in replacement buttstock for AR15/M4 carbines using Mil-Spec sized receiver extension tubes. Dual rear accessible water-resistant battery storage tubes and an integral storage compartment in the butt of the stock provides multiple storage options.

Similar to the Magpul CTR® the ACS also features an anti-snag release latch to prevent accidental activation along with a supplemental friction lock system that minimizes excessive stock movement for enhanced weapon stability and accuracy*. 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 the USA.
