TacFire
The Tacfire Complete Upper with BCG in .300 Blackout is a ready-to-mount upper assembly that gives you a functional shooting platform right out of the box. Built around the versatile .300 Blackout cartridge—a natural choice for suppressed shooting, close-range hunting, and subsonic loads—this 5-inch upper delivers the compact footprint and ballistics that make the caliber so popular among shooters who want flexibility without the bulk. The black finish keeps things clean and professional, and the included bolt carrier group means you're not hunting for parts before you hit the range.
This upper assembly is designed for AR-15 platform shooters who either need a short-barreled hunting or patrol build, or who are building a backup rifle without spending the time sourcing individual components. The .300 Blackout thrives in short barrels, making a 5-inch setup practical for close-quarters accuracy and ballistic performance. If you're already running an AR lower, this upper slides on and bolts down to complete your rifle.
TacFire offers reliable, no-frills components at a sensible price point—the kind of gear that works without trying too hard to impress. Whether you're working up a new build, replacing an upper, or experimenting with a different cartridge on your existing platform, a complete upper with BCG included cuts out the assembly work and gets you shooting faster.

| Finish | Black |
| Includes | Bolt Carrier Group |

This is a Tacfire .300 Blackout upper designed for standard AR-15 platform lower receivers. It will work with most mil-spec AR-15 lowers on the market.
Yes. The BCG is included, so you have all the parts needed to complete your upper assembly without sourcing additional components.
The .300 Blackout is widely favored for suppressed shooting, especially with subsonic ammunition. The 5-inch barrel paired with this caliber is a practical setup for that purpose.
The upper assembly bolts onto a compatible AR-15 lower receiver. No gunsmithing is required—the upper and lower simply mate together with the pivot and takedown pins from your lower receiver.
