Magpul FDE ACS-L Carbine Stock Mil-Spec MAG378FDE

The Magpul FDE ACS-L Carbine Stock Mil-Spec delivers a balance of strength, stability, and reduced weight for shooters who want dependable performance without unnecessary bulk. Built as the streamlined evolution of the original ACS, the ACS-L sheds the integrated battery tubes in favor of a slimmer, more agile profile that still maintains the rugged durability Magpul products are known for. This lighter configuration enhances weapon handling, speeds up transitions, and keeps your rifle responsive whether you're navigating tight spaces, training hard on the range, or carrying your carbine through long days in the field.
At the core of the stock’s reliability is its chrome-silicon locking spring, engineered to deliver a firm lockup on the receiver extension while also ensuring long-term service life. This design keeps the stock secure during firing, reducing wobble and providing a more stable cheek weld. The ACS-L is built to withstand heavy use and harsh environments, making it a dependable upgrade for professional and civilian shooters alike.
Compatibility is broad and straightforward. The stock fits Mil-Spec carbine receiver extension tubes (not included) from major manufacturers including Colt, Armalite, S&W, LMT, and others. Whether you're running an AR15, AR10, M4, M16, M110, or SR25 platform, the ACS-L integrates cleanly and performs consistently. Its 8-inch maximum length and 2.2-inch width keep the stock compact, while the 12.5-ounce weight strikes a solid balance between toughness and reduced mass.
Magpul’s signature ergonomics remain central to the design. The ACS-L maintains the comfortable contours and stable shooting support of the original ACS while improving speed and maneuverability. The FDE colorway provides a professional, field-ready appearance that blends well with tactical builds or outdoor environments.
For shooters seeking a lighter, cleaner, and more efficient stock without sacrificing strength or adaptability, the Magpul ACS-L stands out as a proven, high-performance choice.
