TacFire BU30818 .308 Win 18" M-LOK Complete Upper - Black Nitride

The TacFire BU30818 is a complete .308 Win rifle upper assembly designed to drop onto a mil-spec AR-10 lower receiver (sold separately). It is a turn-key solution for builders who want to bring up an AR-platform rifle in .308 Winchester without sourcing each major component individually, and it ships ready to run with the included bolt carrier group.

At the heart of this upper is an 18" barrel finished in black nitride for improved corrosion resistance, surface hardness, and lubricity over standard phosphate or stainless finishes. The barrel is mated to a 7075-T6 aluminum receiver finished in black anodized, giving the platform the strength and rigidity expected from a duty-grade AR-10 build while keeping weight in check. A free-float M-LOK handguard wraps the barrel, providing a slim, ergonomic platform with plenty of real estate for lights, lasers, bipods, foregrips, or other M-LOK compatible accessories along the sides and bottom.

This upper ships optic ready, allowing you to mount your preferred optic directly to the Picatinny top rail. Once paired with a compatible AR-10 / .308 Win lower receiver, the BU30818 is ready for the range, the hunt, or a long-range precision build.
