Sons of Liberty Gun Works L89 V2 5.56 NATO 13.7" Upper Receiver with NOX – AR-15 Platform

The Sons of Liberty Gun Works L89 V2 is a 5.56 NATO complete upper receiver built on a 13.7-inch barrel with a pinned and welded NOX muzzle device to achieve the legal 16-inch overall barrel length. This configuration delivers a compact, maneuverable rifle without NFA restrictions. Compatible with standard mil-spec AR-15 lower receivers, the L89 V2 is designed for versatile use from home defense to duty applications.

The upper features a forged aluminum receiver with Type III hard-coat anodized black finish and a low-profile gas block for a clean sight picture. The NOX muzzle device provides flash suppression and recoil mitigation. Ships ready to install—no gunsmithing required for standard AR-15 platforms. Verify headspace and function with your specific lower receiver and bolt carrier group before live fire.
