Sons Of Liberty Gun Works BROADSWORDSET89 Broadsword 89 Receiver Set Steel Black Hard Coat Anodized, Includes RH Bolt Release Assembly, Compatible w/M89/L89 Handguards

The Broadsword-89 receivers 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. The 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.
