This billet upper provides a solid foundation for custom builds in 5.56 NATO, .223 Wylde, or other AR-15 chamberings. The upper features a flat-top Picatinny rail for optics mounting and accepts standard AR-15 barrel assemblies and bolt carrier groups.\u003c\/p\u003e\u003cp\u003eMachined from 7075-T6 aluminum billet, this upper offers enhanced rigidity compared to forged alternatives. The Type III hard anodized finish provides corrosion resistance and durability.
