A rotary-style hopup is mated to a 6.01mm fine-polished inner barrel, giving the gun consistent accuracy and hop performance.

About the ARS-Lite Rail System:
The F4 Adaptive Rail System Lite (ARS-L) is a purpose-built rail combining the functionality of the M1913 Picatinny rail and the adaptability of Magpuls MLOK system. The ARS-Lite handguard features both, maintaining a seamless low profile and versatile configuration at the first 5 inches of the rail. The middle of the rail is MLOK only. We designed this feature to lower weight and place the MLOK only section in the area of the rail that does not typically field attachments. Our Patent Pending MLOK and Picatinny Adaptive Rail System (ARS) is directly integrated into the extruded profile of the rail, rather than a bulky quad rail configuration; built into the forward end of the rail that typically fields all attachments. 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 attachment system is the most user-friendly and effective system on the market. This modular system allows the flexibility to configure the rail based on the end-users individual preferences.
