Magpul MOE Carbine Stock Mil-Spec for AR15/M4

The benchmark carbine stock — A-frame strength, clean ergonomics and the best value-per-pound upgrade in the AR world.

The Magpul MOE Carbine Stock (MAG400) replaced millions of rattling, sharp-edged mil-issue stocks for good reason. Its A-frame profile adds structural rigidity while shielding the adjustment lever from accidental release, and the sloped cheek weld area gives a comfortable, consistent reference for your face — shot after shot. Multiple sling attachment options, including slots on both sides, rig cleanly for any carry style.

Built from Magpul's reinforced polymer, the MOE handles impacts, solvents and temperature swings without complaint. For a first build, a working truck gun or a fleet upgrade, nothing else delivers this much genuine improvement per pound spent.

Why shooters choose the MOE Carbine Stock

• Rigid A-frame profile — stronger structure, protected release lever
