AR-15 5.56 “Slabside” Stripped Billet Upper Receiver (Flat Dark Earth)

Description

This stripped billet upper receiver is machined from 6061 T6 Billet Aluminum and finished in Cerakote Flat Dark Earth. It features a full-length 1913 Picatinny Rail Flat Top for optics and accessories, along with M4 Feed Ramp geometry to ensure reliable cartridge feeding. The Slim Profile Brass Deflector provides ejection management while reducing overall mass. Designed for builders who prefer a lightweight platform, this upper weighs 7 oz and omits the forward assist to save weight and simplify the design. It accepts both Milspec or Gen 3 Dust Covers, offering flexibility for various lower receiver configurations. The slab-side construction provides a clean aesthetic and reduced profile compared to traditional forged uppers. This component is supplied unassembled, requiring the builder to install the bolt carrier group, charging handle, and barrel assembly. It is engineered for 5.56 Caliber operation, ensuring compatibility with standard 5.56 ammunition and magazines. The receiver is built to strict tolerances, providing a solid foundation for a custom AR-15 build. The Flat Dark Earth finish offers durability and corrosion resistance, suitable for field use. This upper is a critical component for assembling a custom rifle, allowing for precise selection of barrels, gas systems, and handguards to match specific performance requirements.
