Reptilia 15" AR15 ARCA Black Handguard 100-399

The Reptilia 15" 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 shooting accessories. Like other entries in the Reptilia handguard line, it utilizes patented turnbuckle technology and a standard 1.25-inch driven barrel nut to provide a rigid, anti-rotational lockup without the need for traditional anti-rotation pins. Precision-machined from 6061-T6 aluminum extrusion, this 15-inch rail offers a low-profile ergonomics-focused design with M-LOK mounting slots at the 3 and 9 o'clock positions and a full-length Picatinny top rail. The system is finished in MIL-STD Type III hardcoat anodizing, ensuring a durable, non-reflective surface suitable for competitive long-range shooting and professional duty applications.
