Magpul ACS Carbine Stock MAG370 OD Green Mil-Spec AR-15 M16 M4

The Magpul ACS Carbine Stock delivers enhanced stability and storage capacity for AR-platform rifles through its dual-compartment design and friction lock system. This MAG370-ODG model combines tactical functionality with the proven reliability that has made Magpul stocks a standard across military and law enforcement agencies.

What Makes This Different

Unlike standard carbine stocks, the ACS features dual water-resistant storage compartments that hold CR123 batteries, spare parts, or cleaning supplies without adding bulk. The friction lock system eliminates buffer tube play and wobble found in mil-spec stocks, creating a solid cheek weld and consistent sight picture. The rubberized buttpad reduces felt recoil while the dual QD sling attachment points provide ambidextrous mounting options.

Key Features

• Dual water-resistant storage compartments for batteries and accessories
• Friction lock system eliminates stock wobble on mil-spec buffer tubes
• Rubberized anti-slip buttpad with 0.70-inch length of pull extension
• Ambidextrous QD sling attachment points rated for 300 pounds
• OD Green finish matches military specification color standards

• Reinforced polymer construction withstands temperature extremes

Field testing has demonstrated the ACS stock's ability to maintain zero consistency across multiple shooting positions. The storage compartments remain sealed during rapid fire sequences and adverse weather conditions. Competition shooters benefit from the stable platform during extended strings of fire, while tactical users appreciate the secure storage for mission-essential items. The stock maintains functionality in temperatures from -40°F to 140°F.
