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