Magpul MAG404-FDE MOE Rifle Stock for AR-15/M16/M4 - Flat Dark Earth Synthetic

The Magpul MAG404-FDE MOE Rifle Stock is a direct replacement for standard A1 or A2 fixed stocks, bringing modern ergonomics and practical features to your AR-15, M16, or M4 platform rifle. If you're running a fixed-stock setup and want better cheekweld comfort, easier shoulder mounting, and onboard storage without a complete rebuild, this Flat Dark Earth synthetic stock delivers genuine upgrades in handling and usability.

The sloped comb is designed to support a consistent, secure cheekweld while keeping the overall profile trim—important if you're working in tight spaces or prefer a sleeker silhouette. The rubberized recoil pad absorbs impact and locks the stock firmly against your shoulder, reducing felt recoil and helping you stay on target. A hinged buttplate flips open to reveal internal storage space for cleaning patches, small tools, or other essentials you want to keep on the rifle.

Sling attachment is built in: an integral sling loop accepts a 1¼" sling, and the stock includes front and rear attachment points on both sides to mount Magpul's Type 1 Sling Mount Kit (sold separately), which enables QD swivel connections for faster transitions. Two bosses on the underside can be knocked out if you want to attach a MOE accessory rail for lights or other tactical gear. The stock is also compatible with Magpul PRS extended recoil pads if you want to upgrade the pad down the road.

Magpul's MOE line has become the standard for AR ergonomics because the design works: proven in the field, engineered for real handling, and built to last. Flat Dark Earth is a versatile neutral tone that pairs well with most builds and environments.

Specifications

Frequently Asked Questions

Will this MOE stock fit my AR-15?

Yes—the MAG404-FDE is designed as a direct replacement for A1 or A2 fixed stocks on AR-15, M16, and M4 platforms. If your rifle has a standard fixed-stock tube (not a buffer tube for collapsible stocks), this stock will install without modification.

Can I attach a QD sling mount to this stock?

The stock includes integral attachment points (front and rear on both sides) that accept Magpul's Type 1 Sling Mount Kit, which enables QD swivel connections. The kit is sold separately. There's also an integral 1¼" sling loop if you prefer a traditional sling connection.

What's inside the buttplate storage compartment?

The hinged buttplate opens to reveal a spacious internal compartment. Magpul doesn't specify contents, but it's sized for small items like cleaning patches, lubricant, spare rounds, or tools—typical field essentials you'd want to keep on the rifle.

Can I upgrade the recoil pad?

Yes. The stock is compatible with Magpul PRS extended recoil pads if you want a different pad profile or thickness later.
