Reptilia 13" AR15 ARCA Black Handguard 100-397

The Reptilia 13" AR15 ARCA Handguard is a specialized free-float rail system that integrates a full-length ARCA-Swiss rail along the 6 o'clock position for direct attachment to tripods and precision support systems. Like the rest of the Reptilia handguard line, it features patented turnbuckle technology that uses a reverse-threaded nut assembly to apply high-tension pressure against a standard 1.25-inch barrel nut, ensuring a rock-solid, anti-rotational lockup. Precision-machined from 6061-T6 aluminum extrusion, it offers M-LOK mounting slots at the 3 and 9 o'clock positions and a full-length Picatinny top rail with angled front cuts to improve ergonomics and clearance. The system is finished in MIL-STD Type III hardcoat anodizing, providing a durable, non-reflective surface suitable for long-range precision shooting and tactical applications.
