Sons of Liberty Gun Works M4-L89 5.56mm 14.5" Bbl Mid Gas L89 Rail P&W ASR FH Anodized BLK M4-L89 Complete Rifle M4-L89-556-145-ASR-RIFLE-A-BLK

The Sons of Liberty Gun Works M4-L89 is a professional-tier rifle built for shooters who utilize the SilencerCo ASR mounting ecosystem. This model features a 14.5-inch barrel with a Pin and Welded (P & W) ASR Flash Hider, which brings the legal barrel length to 16 inches, allowing it to be classified as a standard rifle rather than an NFA item. It is built around the high-rigidity L89 Drivelock handguard, which offers a massive barrel nut surface area for superior rail stability. Like all M4-L89 rifles, it utilizes a mid-length gas system paired with the A5 Buffer System, specifically tuned to provide a flatter shooting experience and increased reliability when transitioning between suppressed and unsuppressed fire.
