The Tacfire Complete Upper with BCG in .300 Blackout with an 8" barrel is a ready-to-mount upper receiver built for shooters who want a compact, powerful platform without the assembly hassle. Chambered in .300 AAC Blackout—a cartridge designed for subsonic performance, suppressed shooting, and serious short-range stopping power—this complete upper comes with the bolt carrier group installed, so you can bolt it straight onto your lower and get to work. The 8-inch barrel keeps overall length manageable for close-quarters work, hunting, and home-defense scenarios where a shorter package matters.
The upper features a 1-in-8 barrel twist rate, which stabilizes the heavier projectiles that make .300 Blackout effective. The pistol-length gas system is tuned for the round's ballistics and helps manage recoil in a shorter package. Up top, you get a free-float handguard that isolates the barrel from shooter contact, promoting consistency shot to shot. The barrel is threaded 5/8x24—the standard for .300 Blackout suppressors and muzzle devices—and ships with an A2-style muzzle brake to get you pointed in the right direction.
Finished in matte black, this upper is built to go to work. Whether you're running it suppressed for subsonic work, pushing supersonic loads for hunting, or setting up a short-barrel rifle for tactical training, the Tacfire Complete Upper gives you a solid, no-nonsense platform that saves you the time and tools of upper assembly.

Yes. This is a complete upper receiver designed to mount on any standard AR-15 lower receiver. It arrives ready to install—no gunsmithing required.
Yes. The barrel is threaded 5/8x24, which is the standard thread pitch for .300 Blackout suppressors and muzzle devices. You can attach a suppressor directly once you have the appropriate adapter or direct-thread can.
Yes. The BCG is included and already installed in the upper receiver, so you can mount this to your lower and fire without additional components.
A free-float handguard does not touch the barrel, allowing the barrel to vibrate naturally without interference from the shooter's grip. This typically improves accuracy by reducing harmonics that can throw shots off target.
