F4 Defense ARS Rail System Handguard 15,5"

The F4 Adaptive Rail System (ARS) is a purpose-built rail combining the functionality of the M1913 Picatinny rail and the adaptability of Magpul’s MLOK system. The ARS handguard features both, maintaining a seamless low profile and versatile configuration. Our Patent Pending MLOK and Picatinny hybrid system is directly integrated into the extruded profile of the rail, rather than a bulky quad rail configuration. No more adapter rails; accessories are attached directly to the rail. Strategic machining allows for maximum venting, air flow, and weight reduction while maintaining the structural integrity to maintain accuracy and repeatability. The barrel nut features an anti-rotation design. This modular system allows the flexibility to configure the rail based on the end-users individual preferences.
