Magpul MAG400-FDE MOE Carbine Stock for AR-15/M16/M4, Flat Dark Earth, Mil-Spec Tube Compatible (Tube Not Included)

The Magpul MOE Carbine Stock in Flat Dark Earth is a proven, no-frills buttstock designed to give AR-15, M16, and M4 shooters a more comfortable, controllable shooting platform without the price tag of premium alternatives. Built on an A-frame design that's both lightweight and rigid, this mil-spec tube-compatible stock brings genuine ergonomic gains—wider comb contour, intuitive controls, and sling attachment options—to any carbine that runs a standard 1.14" O.D. buffer tube.

Magpul engineered this stock for real-world use: the release lever is protected from snagging on gear and vegetation, the polymer is reinforced at stress points to handle hard use, and the rubber buttpad won't slip on your shoulder or absorb impact. Whether you're running a duty rifle, a hunting carbine, or a range gun, this is the kind of accessory that disappears into the background and just works. It's adjustable across multiple positions, includes slots for web slings and a hole for a sling swivel, and feels solid every time you shoulder the gun.

Drop-in installation on any mil-spec platform means no gunsmithing required—as long as your tube is genuine mil-spec (note: tube not included). The MOE stock has been in service long enough that you'll find hard data on reliability, and Magpul's reputation for durability backs it up. If you've been running factory plastic or want a stock that prioritizes function over flash, this is a smart, affordable upgrade.
