The Sons of Liberty Gun Works SOLGW L89 SBR 12.5" 5.56 BLK is built for demanding shooters who want a refined, duty-grade AR-15. Centered around SOLGW’s forged receiver set and Liberty Fighting Barrel, this short-barreled rifle uses the L89 Drivelock M-LOK handguard with 7-sided slots and integral steel QD cups, giving a rigid, secure interface for lights, grips, and other accessories. An extended steel barrel nut and enhanced A5-length buffer system work together to keep the rifle smooth, controllable, and consistent shot after shot.

This 12.5" 5.56 NATO model features a semi-automatic action, adjustable stock, and 30-round magazine, making it well suited for range work, training, and general-purpose defensive roles where compact handling is important. The Liberty 2-stage trigger, Liberty Charging Handle, and ambidextrous safety provide a clean trigger break, positive charging, and intuitive controls. Each rifle is individually built and test-fired, reflecting Sons of Liberty Gun Works’ focus on reliability and craftsmanship.
