TacFire AR-15 Complete Built Upper 5.56 NATO 16"
$285.11
The TacFire AR-15 complete built upper in 5.56 NATO with a 16-inch barrel gives you a ready-to-run upper assembly that handles everything from range days to practical rifle courses. Rather than piecing together your own upper or settling for a bare receiver, a complete upper like this one comes assembled and tested, so you can mount it to a lower receiver and get to work. It's chambered in 5.56 NATO—the standard rifle round for most AR shooters—and the 16-inch barrel hits a practical sweet spot for accuracy and velocity without excess length or unwieldy gas impulse.
TacFire builds these uppers with the kind of straightforward, no-frills approach that appeals to hunters, competition shooters, and home builders who want a solid platform without paying for unnecessary extras. Whether you're assembling your first AR, building a second rifle, or swapping uppers to change your setup, a complete upper simplifies the job: no headspace concerns, no detailed bolt carrier group and charging handle sourcing, no guessing about gas tube length or handguard fit. Just bolt it on and confirm zero.
The 16-inch barrel length offers a practical balance of velocity and handling. It's short enough for vehicle storage, room entries, or transitional shooting, yet long enough to wring solid ballistic performance from the 5.56 round. If you're building a general-purpose rifle or an upgrade upper for an existing lower, this TacFire complete upper takes the guesswork out of the upper half of the equation.

Is a 16-inch barrel appropriate for hunting and tactical use?
