Sons of Liberty Gun Works Broadsword FCD 5.56 NATO Rifle - 16" - HUX - 1x 30rd - AR-15 Rifle

The Sons of Liberty Gun Works Broadsword FCD 16-inch rifle puts the billet Broadsword upper receiver and L89 Drivelock platform into a full-length 5.56 NATO rifle configuration — the tightest tolerances in SOLGW's upper lineup, the most rigid two-piece handguard construction they offer, and a HUXWRX flash hider for direct suppressor integration, in a complete black rifle that delivers Broadsword precision in a standard carbine package.

The SOLGW Broadsword FCD 16-inch rifle is a complete semi-automatic 5.56 NATO AR-15 built on a billet Broadsword upper receiver and L89 Drivelock M-LOK handguard. Features a 16-inch Liberty Fighting Barrel, 4140 steel gas block with nitrided gas tube, Drivelock barrel nut system with anti-rotation tabs and internal dowel pin between upper and rail, integral steel QD cups at the barrel nut on both sides, and a HUXWRX flash hider. Finish: black. Complete rifle — BCG, charging handle, and lower components included.

The 16-inch barrel is the full-velocity configuration of the Broadsword FCD lineup — where the 14.5-inch P/W variant prioritizes a shorter overall package with a permanently attached muzzle device, the 16-inch delivers the complete ballistic output of the 5.56 NATO cartridge with a standard-length barrel that provides the most favorable gas dwell time for reliable cycling across the broadest range of ammunition and suppressor combinations. For shooters who are not constrained by overall length requirements — who want maximum velocity, the cleanest gas system starting point for suppressed use, and the option to change muzzle devices without managing a P/W configuration — the 16-inch is the correct choice. The billet Broadsword upper receiver's tighter dimensional tolerances at the barrel extension interface provide a more consistent headspace and a more precise upper-to-lower fit than a standard forged upper, establishing the accuracy foundation that the Liberty Fighting Barrel is built to exploit. The L89 Drivelock system's three-point lockup — extended barrel nut, internal dowel pin, and anti-rotation tabs — delivers SOLGW's most rigid two-piece upper-to-handguard connection, minimizing the micro-movement that degrades point-of-impact consistency for operators running laser aiming modules or VAS systems. Integral steel QD cups at the barrel nut on both sides provide hardened sling attachment without separate hardware. The HUXWRX flash hider provides direct QD compatibility with the HUXWRX FLOW suppressor series without an adapter.

16-inch barrel delivers full 5.56 NATO velocity and the most favorable gas dwell time for reliable cycling and suppressor-compatible tuning — no P/W constraint, muzzle device swappable. Billet Broadsword upper provides tighter tolerances than forging for a more consistent barrel extension fit. L89 Drivelock three-point lockup minimizes POI shift for lasers and VAS. HUXWRX flash hider provides direct FLOW suppressor QD compatibility.
