Description
The Sons of Liberty Gun Works M4-EXO3 Barreled Upper is a duty-ready, non-NFA upper receiver group optimized for use with Huxwrx Flow-series suppressors. It features a 14.5-inch Liberty Fighting Barrel with a Pin and Welded (P& W) Huxwrx Flash Hider, bringing the permanent overall length to the legal 16-inch requirement for standard rifles. The EXO3 handguard provides a slim, lightweight M-LOK mounting solution that sheds weight compared to the L89 series while maintaining the structural integrity required for hard-use applications. This configuration utilizes a mid-length gas system, providing a balanced and reliable recoil impulse that is particularly effective for consistent cycling when shooting suppressed.
