Sons Of Liberty Gun Works Broadsword-89 223 Wylde 16'' Bbl 15'' M89 Rail W/Nox

The Sons of Liberty Gun Works Broadsword-89 upper receiver in .223 Wylde is purpose-built for shooters who demand rock-solid performance under real-world conditions. This 16-inch barreled upper combines precision engineering with the rugged reliability that separates a shooter's rifle from everyone else's. The Broadsword-89 platform takes the proven design of its predecessor and adds a critical upgrade: M89-spec relief cuts on the receiver face that lock your handguard down with zero flex, even under aggressive bipod and barricade loading. That means your point of impact stays where you aim it, shot after shot.

What makes the Broadsword-89 stand out starts with reinforcement along the entire receiver profile. This beefier construction stiffens the barrel-to-optic interface, which translates to the accuracy consistency you need whether you're running precision matches or hunting. The forward-assist has been repositioned to give your charging handle more clearance for southpaw shooters—a small detail that matters when you're running drills or working through stages. The 15-inch M89 rail gives you ample real estate for mounting support gear, lights, or other optics without sacrificing the clean, purposeful aesthetics of a modern AR.

This upper ships with a Nox flash hider and a SOLGW Precision Rifle Barrel, both proven components in the field. Keep in mind you'll need to source a bolt carrier group and charging handle separately—this is the upper receiver assembly only. Built for shooters who understand that lockup and structural integrity aren't marketing buzzwords; they're the foundation of a reliable rifle.

Frequently Asked Questions

What ammunition does the .223 Wylde chamber accept?

The .223 Wylde chamber is optimized for both .223 Remington and 5.56 NATO ammunition, giving you flexibility at the range or in the field.

What's the advantage of the M89 handguard interface?
