The Reptilia 15" AR15 ARCA Handguard is a full-length, free-float rail system purpose-built for precision shooters who require a seamless interface between their rifle and tripod systems. This handguard integrates a full-length ARCA-Swiss rail along the 6 o'clock position, facilitating rapid and secure attachment to ball heads and precision supports without the need for additional bolt-on adapters. Like the rest of the Reptilia handguard family, it utilizes patented turnbuckle technology and a standard 1.25-inch driven barrel nut to achieve a rock-solid, anti-rotational lockup that resists shifting during high-stress use. Precision-machined from 6061-T6 aluminum extrusion, it features M-LOK mounting slots at the 3 and 9 o'clock positions and a continuous Picatinny top rail, all finished in a rugged MIL-STD Type III hardcoat anodizing in Black.
