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 seeking a reliable foundation for custom rifle assembly. This stripped upper receiver serves as the core control group housing for bolt carrier operation, making it essential for gunsmiths, military contractors, and civilian shooters who demand quality components without the premium price tag. Whether you're assembling a precision rifle for duty use, competitive shooting, or home defense, a properly engineered upper receiver is foundational to overall system reliability and accuracy.

Manufactured from 7075-T6 aluminum alloy and finished with military-spec black anodize, this receiver combines lightweight durability with corrosion resistance demanded in field environments. The 7075-T6 aluminum alloy is the same aerospace-grade material used in high-stress military platforms, providing superior strength-to-weight ratio compared to commercial-grade alternatives. The black anodized finish not only delivers a professional appearance but also provides Type II anodize protection against salt spray, moisture, and environmental degradation. At 0.6 pounds, this stripped upper maintains the weight efficiency critical for ergonomic rifle handling during extended operations or training cycles.

This receiver is optimized for 5.56x45mm NATO ammunition platforms and accepts standard AR-15 bolt carrier groups, charging handles, and rail systems. Builders installing the TacFire UP01C should pair it with a compatible lower receiver assembly, bolt carrier group, and charging handle to complete the upper assembly. The compact dimensions (3.9 x 2.6 x 10 inches) ensure compatibility with standard AR-15 handguard lengths and mounting systems used across law enforcement, military, and civilian precision rifle builds. This is an ideal choice for duty rifles, competition platforms, and general-purpose carbines where component quality and cost-effectiveness intersect.
