Magpul's ACS-L is a lightweight, drop-in replacement buttstock for AR-15 and M4 carbines with mil-spec tubes. Features integrated storage and ergonomic cheek weld in a streamlined package.
Fits: AR-15
The Magpul ACS-L (Adaptable Carbine Stock - Light) represents a refined approach to AR-platform ergonomics. This drop-in replacement buttstock is engineered specifically for AR-15 and M4 carbines using mil-spec sized receiver extension tubes.
The ACS-L is a streamlined evolution of Magpul's proven ACS design. By removing the battery storage tubes found on the full-size ACS, Magpul has created a lighter, more compact stock without sacrificing the features that matter most to shooters.
Whether you're building a carbine for tactical training, competition, or general shooting, the ACS-L delivers the balance of functionality and simplicity that serious shooters demand. The integrated storage keeps essentials within reach, while the refined ergonomics ensure consistent performance across different shooting positions.
