The BROADSWORD-89 receivers take what SOLGW loved about the BROADSWORD and make the handguard lockup even stouter than before. With relief cuts on the upper receiver’s face, the BROADSWORD-89 upper seamlessly integrates with their M89/L89 handguards. This enhanced lockup further reduces flex, so aggressive bipod and barricade loading will have the least impact on POI shift of any combination they’ve ever tested.
