Sons of Liberty BROADSWORD89UR Billet Upper Recv

The BROADSWORD-89 receivers are the updated incarnation of our beloved BROADSWORD, now with an even more robust handguard lockup. The presence of relief cuts on the upper receiver\'s face means that the BROADSWORD-89 upper merges flawlessly with the M89/L89 handguards. This advanced lockup minimizes fail flex to an unprecedented degree, ensuring that aggressive bipod and barricade loading will barely affect the POI shift. Throughout our extensive testing, this combination has consistently delivered the least impact on the POI shift.
