M4-EXO3-556-145-SBR-A-BLK
The Sons of Liberty Gun Works M4-EXO3 is a mission-ready Short Barreled Rifle (SBR) that balances compact handling with full-velocity 5.56 NATO performance. As part of the "Fighting" series, it features a 14.5-inch combat-grade barrel with a mid-length gas system, providing a smoother recoil impulse and reduced parts wear compared to shorter systems. The EXO3 handguard offers a slim, lightweight M-LOK mounting platform while maintaining the rigidity necessary for duty use. Internally, the rifle is optimized with the A5 Buffer System for reliable cycling across various environmental conditions and the Liberty Fighting Trigger for a crisp, duty-weighted break. Because it is a factory SBR, it does not require a pinned and welded muzzle device, allowing users to easily swap the standard A2 flash hider for their preferred suppressor mount.
