The TacFire BU-308-20 Rifle Upper Assembly brings a ready-to-run .308 Win AR-platform upper together in one complete package. Built around a 20" black nitride barrel and a black anodized 7075-T6 aluminum receiver, it pairs a slim M-LOK handguard with an A2 flash hider to deliver a balanced, smooth-shooting upper that installs directly onto your compatible AR-10 style lower.

This complete upper arrives fully assembled with a bolt carrier group and is optic ready, letting you add the glass of your choice on the full-length top rail. The 20" barrel length supports excellent downrange performance for range work, training, and hunting where the .308 Win cartridge shines. TacFire’s attention to detail and solid machining make this upper a dependable upgrade for shooters looking to step into or refine a .308 AR build.
