This forged 7075-T6 flat-top stripped upper provides a solid, mil-spec foundation for custom AR builds. Its hardcoat anodized finish and installed forward assist/ejection door simplify assembly while leaving the core choices—barrel, gas system, handguard, charging handle, and bolt carrier group—up to the builder. It is well suited for competition builds, precision-oriented projects, and general purpose range platforms where durability and compatibility with M4-spec components are priorities.
