Magpul ACS® Carbine Stock – Mil-Spec | FDE

The Magpul ACS® (Adaptable Carbine/Storage) Carbine Stock in Mil-Spec configuration is the ideal drop-in replacement stock for AR15/M4 carbines with Mil-Spec-sized receiver extension tubes. Designed for maximum functionality and reliability, the ACS® Carbine Stock combines intelligent storage solutions with proven Magpul quality – made in the USA.

Versatile storage directly on the stock

Two rear-accessible waterproof battery tubes and an integrated storage compartment in the stock butt provide practical and protected storage for batteries, spare parts or other small items – directly on the weapon, always within easy reach.

Maximum stability and safety

Like the proven Magpul CTR®, the ACS® features an anti-snag release latch that reliably prevents accidental activation. An additional friction lock system minimizes excessive stock movement, noticeably increasing the weapon's stability and precision.

Secure hold – even with protective gear

The ACS® Carbine Stock comes standard with a 0.30" thick rubber recoil pad. This ensures a secure, non-slip fit against the shoulder – even when wearing body armor or modular tactical gear.
