The Timber Creek Outdoors Greyman Adjustable Billet Dust Cover Forest (Model GBDCF, UPC 816397028288) is a premium AR-15 dust cover upgrade designed to protect your rifle’s internals while adding a clean, custom look to your build. Machined from aircraft grade aluminum and finished in a rich Forest Green color, this Greyman-series cover combines durability, adjustability, and sleek styling to outperform standard stamped steel doors.
Adjustable Billet Dust Cover for AR-15 Uppers
The Greyman Adjustable Billet Dust Cover – Forest is built specifically for the AR-15 platform:
Platform: AR-15 upper receiver dust cover
Adjustable fit: Designed to ensure it fits any mil-spec and most billet uppers and ejection ports, so it works with a wide variety of receivers and custom builds.
The adjustment feature lets you fine-tune how the door sits and closes, giving you a precise, rattle-free fit that many basic covers can’t match.
Aircraft Grade Aluminum – Lightweight & Durable
Unlike thin stamped steel doors, the GBDCF Greyman dust cover is crafted from aircraft grade aluminum:
This gives you a dust cover that is:
More resistant to bending and denting than cheap stamped covers
Lightweight enough that it won’t affect rifle balance
Built to handle real-world range, training, and field conditions
Forest Green Greyman Finish – Clean, Modern Aesthetic
Part of Timber Creek’s Greyman series, this model comes in a stylish Forest Green finish:
Retailers list this specific color as “Forest” or Forest Green, matching other Greyman components.
Pairs perfectly with FDE, black, OD green, and other earth-tone builds.
Ideal for woodland, hunting, or general-purpose AR-15s where you want more character than plain black but still a tactical look.
If you’re already running Timber Creek rails, stocks, or small parts in Forest, this dust cover helps tie your entire build together visually.
Protects Your Rifle’s Internals from Dirt & Debris
Functionally, the Greyman Adjustable Billet Dust Cover is designed to keep your rifle running clean:
Shields the bolt carrier group and chamber from dust, dirt, sand, and debris when the rifle is slung or stored.
Springs open when the rifle is fired or manually charged, just like a standard cover, to allow reliable ejection.
Especially useful on field rifles, truck guns, hunting carbines, and defensive AR-15s that see varied environments.
A better-fitting, more durable dust cover means fewer contaminants getting in—and more confidence when it’s time to run the gun.
Easy Installation – Includes All Hardware
Swapping your dust cover is a simple, high-impact AR-15 upgrade, and Timber Creek makes it straightforward:
The GBDCF comes with all hardware needed for installation, so you don’t have to scavenge parts from your old cover.
Designed for DIY installation using standard armorer tools; if you can field-strip an AR-15 and remove the upper, you can install this cover.
This makes the Forest Greyman dust cover a great choice for home builders, hobbyists, and professional armorers alike.
Perfect Match for Other Timber Creek Greyman Parts
If you’re building a cohesive rifle, the Greyman Adjustable Billet Dust Cover Forest coordinates with the rest of the Greyman lineup:
Pairs with Greyman charging handles, buffer tubes, takedown pins, trigger guards, and more offered in matching Forest, Urban, Stealth, Desert, and Black colors.
Gives your AR-15 a consistent, high-end look instead of a mix of mismatched parts.
For builders who care about both performance and aesthetics, that unified appearance is a big plus.
