The TacFire BU3005 300 Blackout 5" Black Nitride Barrel Complete Upper Assembly is built around a compact 5 inch barrel chambered in .300 AAC Blackout, delivering a streamlined AR-15 upper that emphasizes reliability and smooth cycling. The black nitride barrel finish enhances surface hardness and corrosion resistance, while the included A2 flash hider and free-floated handguard with lightening cuts keep the package nimble and easy to maneuver. This upper ships complete with a bolt carrier group, giving builders a ready-to-install solution for their next .300 Blackout project.

With its short 5 inch barrel and lightweight profile, this upper is well suited for compact builds, range use, and training setups where quick handling and reduced overall length are priorities. The .300 AAC Blackout chambering supports versatile ammunition choices, and the nitride treatment helps the barrel stand up to extended shooting sessions. TacFire’s focus on practical design and dependable machining makes the BU3005 a solid foundation for shooters looking to upgrade or assemble a dedicated .300 Blackout AR platform.
