Assembled AR 15 Upper Receiver

This assembled AR-15 Upper Receiver is a high-quality, mil-spec flat-top upper built for reliable fitment and long-term durability. Machined from top-tier 7075-T6 forged aluminum, it’s shot-blasted prior to anodizing for a more consistent, uniform finish—avoiding the chalky or purplish anodizing seen on lower-grade uppers.

It comes fully assembled with a mil-spec forward assist and dust cover sourced from top-tier OEM/military suppliers, plus M4 feed ramps for dependable feeding. Small details like slightly chamfered lug holes help smooth takedown/pivot pin engagement, making this an excellent foundation for new builds or upgrades.
