M-4-Style Upper With Popular Features; CNC Machined From 7075 Aluminum Forging

The same high-quality M4-style flattop upper Wilson uses in their custom AR-15s is now available to serve as the foundation for your own custom build. Comes ready for you to install the required components to meet your—or your customer’s—exact needs. Includes integral receiver rail cut to MIL-STD 1913 Picatinny specs, M4-type feed cuts, shell deflector, forward assist housing, and provisions for installing an ejection port cover, if desired (available separately). Precision CNC-machined to final dimensions from a U.S.-sourced forging of high-grade 7075 T6 aluminum alloy, prized by AR shooters for its exceptional strength, hardness, and resistance to surface wear. Hardcoat anodized for additional surface hardness, with a durable matte black finish.
