The Black Rain Ordnance FDE Upgrade Kit #1 is a coordinated ergonomic and handling overhaul for your AR-platform rifle, built around a cohesive flat dark earth color scheme. This kit bundles four core components—Magpul stock, grip, forend rail, and gas management hardware—so you get a matched aesthetic and feel without hunting across suppliers. It's built for shooters who want to refresh a rifle's controls and furniture in one go, whether you're tuning for hunting, tactical training, or range work.
The kit centers on genuine Magpul ergonomics: a UBR stock with full hardware for secure mounting, and a MOE grip that's proven itself in the field for its textured, intuitive control. The 12-inch hybrid MLOK rail—finished in Cerakote FDE to match the rest—gives you a modular platform for mounting optics, lights, and accessories without over-building the forend. The included .750 adjustable gas block and 5.56 Precision Hex Compensator (with crush washer) round out the package, addressing both gas system tuning and muzzle management. All hardware is included, so assembly is straightforward for anyone comfortable with basic AR work.
Black Rain Ordnance has packaged this kit for builders and upgraders who prefer a unified color story and don't want to cobble together parts from different vendors. The flat dark earth finish is professional and practical, blending into most field settings while staying visually coherent on the bench and at the range. This is a no-nonsense upgrade path for a rifle that's already running, or a smart start for a new build.
| Brand | Black Rain Ordnance |
| Kit Contents | Magpul UBR Stock (with hardware), Magpul MOE Grip, 12" Hybrid MLOK Rail (Cerakote FDE), .750 Adjustable Gas Block, 5.56 Precision Hex Compensator (with crush washer) |
| Color | Flat Dark Earth (FDE) |
| Rail Length | 12 inches |
| Gas Block Size | .750 inch |
| Compensator Caliber | 5.56 |
This kit is built for standard AR-pattern rifles in 5.56 chambering. The .750 gas block and compensator are calibrated for that cartridge. Confirm your upper receiver is configured for standard AR furniture before ordering.
The stock, grip, and forend rail are user-installable with basic tools and familiarity with AR assembly. The gas block and compensator installation may require removal of the barrel and upper; if you're not comfortable with that work, a qualified gunsmith can handle it quickly and affordably.
Yes—the kit includes all mounting hardware needed for the stock, grip, rail, gas block, and compensator. You'll need standard AR tools and punches if you don't already have them.
The 12-inch hybrid MLOK rail provides a modular platform for MLOK-compatible accessories. If your current optics and lights use MLOK, they'll mount directly. Standard Picatinny rail attachments will require MLOK-to-Picatinny adapters (not included).
