TacFire
Building or upgrading an AR-pattern pistol? The Tacfire Complete Upper with BCG in .45 ACP gives you a ready-to-install upper assembly for short-barreled platforms. This 10-inch upper comes fully assembled with bolt carrier group included—no hunting for compatible parts or wrestling with assembly. If you're running a .45 ACP lower receiver and need a functioning upper to complete the gun, this is a straightforward bolt-on solution that gets you shooting faster.
Tacfire handles their own manufacturing, so you're looking at practical, no-frills components designed around reliability and value. The 10-inch barrel length is right at home in modern pistol caliber carbines (PCCs) and AR pistols where you want velocity but not a rifle-length platform. The upper arrives in black, matching most modern AR builds cleanly.
This is ideal for shooters who already have a .45 ACP lower receiver sitting around—or those committed to the caliber for subsonic and suppressed shooting. Whether you're into pistol-caliber competitions, home defense builds, or just want another configuration without buying a complete gun, a quality upper assembly from a manufacturer you can count on makes the job simple.
| Caliber | .45 ACP |
| Barrel Length | 10 inches |
| Finish | Black |
| Includes | Bolt Carrier Group (BCG) |
| Manufacturer | Tacfire Inc. |
You'll need a .45 ACP lower receiver and a charging handle. This upper assembly arrives complete with the bolt carrier group, so mating it to a compatible lower finishes the build.
Yes, this upper is designed for use with AR-pattern lower receivers chambered in .45 ACP. Verify your lower is compatible with this caliber before assembly.
The upper assembly and bolt carrier group are included. You'll supply the lower receiver and charging handle separately.
The 10-inch barrel and .45 ACP chambering make this a natural fit for subsonic and suppressed configurations, which is a common use case for this caliber.
