Exactly what I expected. by Nelson, Verified Owner, December 10, 2025
This product is excellent and pairs wonderfully with the L89-Broadsword handguard and lower FCD from SOLGW. It offers a perfect fit, and the price and service from Optics Planet are commendable.

Product Info for Sons of Liberty Gun Works Broadsword-89 Billet Stripped Upper Receiver

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 rail flex even further, so aggressive bipod and barricade loading will have the least impact on POI shift of any combination we've ever tested.image

As before, the BROADSWORD receivers have a few notable features that their standard Forged receivers do not.

Please note, with the ejection port rod being captured within the upper receiver now, the use of knurled port door rod is prevented. Please use a traditional port door rod with these upper receivers. These billet receivers are compatible with standard forged lowers, as well as their accompanying billet Broadsword lowers.

Features:

The upper receiver is significantly reinforced along its entire profile to stiffen the interface between the barrel, handguard, and mounted optics.

The Forward Assist has been shifted forward so left handed manipulations of the charging handle have added clearance.

The upper receiver is precision machined to seamlessly interface with the entire 89 series of handguard.
