Tacfire Complete Upper W/ Bcg .300 Blackout 16" Black
$346.99
The Tacfire Complete Upper with BCG in .300 Blackout, 16" barrel, is a ready-to-run upper assembly built for shooters who want a complete, no-hassle upgrade or a foundation for a new rifle build. Whether you're assembling a subsonic hunting rig, a suppressed range gun, or a .300 BLK platform for tactical practice, this upper arrives with the bolt carrier group installed—no need to source parts separately or deal with compatibility guesswork. The 16" barrel length strikes a practical balance between velocity and handling, especially relevant for the .300 Blackout cartridge, which performs best in that barrel range and pairs well with suppressors.
Tacfire builds their uppers for function over flash, and this one is no exception. The black finish keeps things clean and utilitarian. Since this is a complete upper assembly, you're getting a matched, ready-to-mount unit; drop it onto a compatible lower receiver and you're in business. That approach appeals to builders who prefer to consolidate their sourcing, buyers stepping up from a single rifle, or anyone tired of waiting for individual parts to arrive.
.300 Blackout has earned a solid following among hunters and shooters who appreciate subsonic ammo capability, straightforward ballistics, and the fact that it runs in an AR-platform gun. A complete upper like this one removes one major variable—you know the barrel, bolt, and carrier are set up to work together from the factory.

Frequently Asked Questions
Can I use this upper on my existing AR lower receiver?
This is a complete upper assembly designed for standard AR-pattern lower receivers. Confirm your lower is chambered for .300 Blackout or is compatible with that conversion before mounting.
Does this come with a charging handle and bolt carrier group?
Yes—the BCG is included. Confirm whether a charging handle is included; if not, you'll need to source one separately.
What ammunition does the .300 Blackout barrel support?
The .300 Blackout cartridge is available in both supersonic and subsonic loads. The 16" barrel is effective with both; subsonic loads are particularly popular with suppressors, while supersonic loads deliver higher velocity and flatter trajectory.
Is this upper suitable for suppressed shooting?
The .300 Blackout cartridge and 16" barrel are well-suited to suppressed fire, especially with subsonic ammunition. However, you will need to source a suppressor separately, ensure it is rated for .300 Blackout, and comply with all local, state, and federal regulations.
