Solgw M4 L89 Bs 14.5" Nox 6arc Blk

The Sons of Liberty Gun Works Broadsword 89 with 14.5" Nox Flash Hider in 6mm ARC represents a purpose-built semi-automatic rifle engineered for precision, modularity, and field performance. This model pairs a pinned 14.5" barrel (16" OAL) with Sons of Liberty's Broadsword platform—a modern AR architecture designed around the intermediate 6mm ARC cartridge. The 6mm ARC delivers ballistic efficiency and reduced recoil compared to 5.56mm NATO, making it a capable choice for mid-range engagement, precision training, and tactical applications where energy retention matters.

Key features include the Liberty Two-Stage Trigger for controlled, predictable trigger breaks; a B5 pistol grip for ergonomic control; and the Nox flash hider, which tames muzzle flash and blast signature in low-light or close-quarters scenarios. The 14.5" barrel length provides velocity optimization for the 6mm ARC cartridge while maintaining a compact, maneuverable platform suitable for vehicle ops, building clearance, and training environments. Finished in black, the rifle comes with one 30-round magazine and weighs 12.13 lbs—a balanced weight that reduces fatigue during extended shooting sessions or dynamic drills without sacrificing handling speed.

This rifle appeals to serious shooters, law enforcement trainers, and precision-focused civilian operators who recognize 6mm ARC's advantages in terminal ballistics and barrel life. The Broadsword platform is known for its modular design philosophy, allowing future caliber swaps and accessory customization. Operators evaluating the 6mm ARC for intermediate-range work, those transitioning from 5.56 to a flatter-shooting alternative, and shooters seeking a compact, semi-automatic platform optimized for accuracy will find this rifle purpose-built for their requirements.
