Sons Of Liberty Gun Works Broadsword 89 V2 Complete Upper Features The Sons of Liberty Gun Works Broadsword 89 V2 upper is built around a 14.5 inch 4150 CMV barrel chambered in 5.56 NATO a steel alloy known for its strength and heat resistance under sustained firing. The 7-sided L89 handguard provides M-LOK attachment points across every face giving shooters flexibility to mount lights grips and other accessories wherever they are needed. A titanium barrel nut secures the handguard to the BROADSWORD upper receiver offering a lighter weight alternative to a standard steel nut without sacrificing strength. Integral QD cups built into the handguard allow a sling to be attached directly without needing separate QD mounting hardware. A low profile gas block keeps the overall profile of the handguard slim and snag free improving handling and allowing for a cleaner accessory mounting surface. The included HUXWRX flash hider serves as the muzzle device reducing visible signature when firing. Note that this upper ships without a bolt carrier group or charging handle so those components will need to be sourced separately to complete the build. Finished in black to match most AR-15 lower builds the Broadsword 89 V2 upper is available for sale at GrabAGun for builders seeking a premium well equipped upper assembly.
