TacFire UP01C Stripped Upper Receiver 5.56x45mm NATO 7075-T6 Aluminum Black Anodized Receiver for AR-15

The TacFire UP01C Stripped Upper Receiver 5.56x45mm NATO is a precision-engineered component purpose-built for AR-15 platform builders and field operators who demand reliability without compromise. This stripped upper receiver serves as the foundation for custom rifle builds, allowing shooters to tailor their weapon system to specific mission requirements—whether for law enforcement duty, tactical training, or civilian marksmanship. By starting with a quality stripped upper, you control every variable in your build, ensuring compatibility and performance alignment with your intended use profile.

Constructed from 7075-T6 aluminum and finished with a black hardcoat anodized coating, the TacFire UP01C delivers the durability expected in military and law enforcement environments. The 7075-T6 alloy is the gold standard in tactical aluminum—offering superior strength-to-weight ratio and exceptional corrosion resistance compared to standard 6061-T6 variants. Integrated M4 feed ramps ensure reliable ammunition cycling across all ammunition weights and profiles, critical for duty weapons where feeding failures are operationally unacceptable. The receiver includes both dust cover and forward assist, eliminating the need for separate purchases and reducing build time. Weighing just 0.6 lbs, the compact upper receiver design (10 inches in length) maintains lightweight characteristics essential for extended carry and rapid deployment scenarios.

This stripped upper receiver is ideal for armorer-level technicians, experienced rifle builders, and shooters seeking to assemble a custom 5.56x45mm NATO platform with precision engineering. Installation requires a separate charging handle, barrel, handguard, gas block, muzzle device, and gas tube—allowing builders full customization control. The receiver accepts standard AR-15 components, ensuring broad compatibility across the aftermarket ecosystem. Experienced operators value stripped uppers for their ability to create purpose-built systems tailored to specific threat profiles, training objectives, or competitive shooting disciplines. For those building duty rifles or precision platforms, the TacFire UP01C provides the proven materials and feed reliability needed for field performance.
