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 the 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. SKU: BROADSWORD-89-UR
