The TacFire BU30818 Rifle Upper Assembly brings a ready-to-run .308 Win AR-platform upper to shooters who want a straightforward upgrade. Built around an 18" black nitride barrel and a 7075-T6 aluminum receiver with a black anodized finish, it pairs a slim M-LOK handguard with an A2 flash hider for a clean, modern profile that remains optic ready out of the box. This complete upper includes a bolt carrier group, giving you a fully assembled top end that is prepared to pin onto a compatible lower.

Designed for the AR-10 style platform, this upper is well suited for range use, training, and general-purpose .308 shooting where reliability and simplicity are priorities. The free-float M-LOK handguard offers ample space for lights, bipods, and other accessories, while the 18" barrel balances velocity and handling for versatile performance. With its complete configuration and consistent finish, the BU30818 reflects TacFire’s focus on practical design and solid value for the modern AR builder.
