TacFire UP03 AR-15 Billet Slick Upper Receiver

The TacFire UP03 is a stripped AR-15 billet upper receiver featuring a "slick side" design — no forward assist and no dust cover cutout — machined from billet aluminum with a black anodized finish. As a stripped receiver without a barrel assembly, this unit does not include a barrel, handguard, bolt carrier group, or charging handle. The slick side profile reduces weight and provides a clean, minimalist aesthetic preferred for lightweight or custom AR builds. Compatible with standard mil-spec AR-15 lower receivers and components. Builders must supply all barrel, gas system, and handguard components separately.
