The Magpul MOE (Magpul Original Equipment) rifle stock (brand part no. MAG404-BLK) is a made-in-the-USA drop-in replacement for factory A1 and A2 stocks on any AR-15, M16, or M4 rifle running a standard rifle-length receiver extension. Molded in durable black synthetic, it upgrades the fixed factory stock with a comfortable cheek weld, an integral 1.25-inch sling loop, and quick-detach sling mounting points on both sides for true ambidextrous carry. A replaceable, anti-slip rubberized butt-pad improves shoulder purchase, and an internal storage compartment accessible through the rear door keeps small spares on hand without added bulk.
