Why Choose This Upper
The .300 Blackout cartridge excels in short-barreled rifles, delivering effective performance at intermediate ranges while remaining subsonic-capable with appropriate ammunition. The 10" barrel length makes this upper ideal for home defense, hunting in dense cover, or tactical applications where maneuverability matters.
TacFire's complete upper approach eliminates guesswork. All components are assembled and tested, so you can focus on finishing your build with a quality lower receiver and furniture of your choice.
Building Your Rifle
Simply pair this upper with a compatible AR-15 lower receiver, add a stock and grip, and you're ready to shoot. This modular approach lets you customize your rifle exactly as you want it.
