Building or upgrading an AR-15? The LBE Unlimited ARUPPER upper receiver is a solid, American-made choice for shooters who want a reliable foundation without the hype. Machined from 7075-T6 forged aluminum and hard-coat anodized in black, this 5.56x45mm NATO upper receiver comes complete with forward assist and ejection port cover assembly already installed—so you're not buying a bare component and scrambling for extras. It's ready to pair with your lower and BCG, whether you're running precision rounds downrange or pushing through training cycles at the range.
LBE Unlimited has built its reputation on no-frills, honest AR parts made in the USA. The 7075-T6 aluminum is the same military-grade alloy used in combat rifles and precision builds; it's strong, proven, and significantly more durable than the 6061 aluminum found in budget uppers. The hard-coat anodizing resists wear and corrosion, holding up to dust, sweat, and the occasional neglect. The T-mark on the top rail is standard AR geometry—your optic mounts will index correctly and repeatably.
Whether you're building a hunting rifle, a competition gun, or a reliable home-defense AR, this upper receiver handles the job without cutting corners or draining your budget. No unnecessary bells, no proprietary features—just a solid piece that fits the platform and works.

7075-T6 is military-grade aluminum—stronger and more durable than the 6061-T6 aluminum commonly used in budget uppers. It holds up better under sustained use and resists stress fractures, making it a smart choice for shooters who demand reliability.
Yes, both the forward assist and ejection port cover assembly come pre-installed and ready to go. You won't need to source or install these components separately.
