The Sons of Liberty Gun Works Broadsword 6mm ARC delivers precision long-range performance in a compact 14.5-inch configuration. This upper receiver assembly transforms standard AR-15 platforms into capable long-distance shooters while maintaining maneuverability for dynamic situations. The 6mm ARC cartridge provides superior ballistic coefficients and extended effective range compared to traditional 5.56 NATO offerings.
What Makes This Different
The Broadsword upper features a cold hammer-forged barrel with a mid-length gas system optimized specifically for 6mm ARC ballistics. Unlike standard carbine-length systems, this configuration reduces felt recoil and improves accuracy through consistent gas pressure regulation. The barrel profile balances rigidity for precision shooting with weight considerations for extended carry. Chrome-lined bore and chamber construction ensures consistent performance across temperature extremes and extended firing schedules.Key Features
