Magpul ACS Carbine Stock Mil-Spec Stealth Gray

Magpul ACS Carbine Stock: Storage Meets Stability

The Magpul ACS (Adaptable Carbine/Storage) Mil-Spec Model is a purpose-built replacement buttstock designed for AR-15 and M4 carbines equipped with standard mil-spec receiver extension tubes. This is a true drop-in upgrade that transforms your carbine's rear end into a functional storage platform without sacrificing ergonomics or reliability.

Smart Storage Design

Dual Battery Tubes: Two rear-accessible, water-resistant storage compartments keep batteries, small tools, or emergency items protected and organized. The tubes are positioned for quick access without removing the stock.

Integral Butt Compartment: An additional storage cavity in the stock itself provides extra capacity for patches, cleaning supplies, or other essentials.

Stability and Control

The ACS incorporates proven features from Magpul's CTR design:

• Anti-snag release latch prevents accidental activation during tactical movement or rough handling
• Supplemental friction lock system minimizes unwanted stock movement, enhancing weapon stability and shot consistency
• 0.30" thick rubber butt-pad delivers positive shoulder purchase and prevents slippage, even when wearing body armor or modular gear

Built to Last

Manufactured in the USA from durable synthetic materials, the ACS is engineered for reliability in demanding conditions. The Stealth Gray finish blends tactical aesthetics with practical functionality.

Note: Requires a mil-spec diameter receiver extension tube (not included).
