Description
The TacFire UP01C Stripped Upper Receiver is a bare 5.56x45mm NATO upper built as a foundation for AR-15 custom builds, replacement projects, and component-level repair. Constructed from 7075-T6 aluminum and finished in a durable black hardcoat anodized coating, this stripped upper delivers the corrosion resistance and long-term durability serious shooters expect.
Featuring M4 feed ramps to ensure reliable cycling with both 5.56 NATO and .223 Remington ammunition, the UP01C gives you a clean slate to assemble a complete upper to your own specifications. The receiver ships optic ready with no sights installed, so you can pair it with any rail system, handguard, and optic combination.
As a standard stripped upper, the UP01C ships with the basic small parts installed – a forward assist assembly, dust cover assembly, and A2-style charging handle – but no barrel, bolt carrier group, or handguard. This makes it the ideal component for custom AR-15 builds, replacing a damaged upper, or building out a precision, duty, or recreational rifle configuration on a proven 7075-T6 aluminum platform.
