Reptilia 11.5" AR15 ARCA-S FDE Handguard 100-402

The Reptilia 11.5" AR15 ARCA-S Handguard is a specialized free-float rail system designed for the AR15 platform, specifically optimized for shorter-barreled precision builds. This model integrates a full-length ARCA-Swiss rail along the bottom (6 o'clock) position, providing a direct and secure interface for tripods and precision support systems without requiring extra adapters. Like the rest of the Reptilia handguard line, it utilizes patented turnbuckle technology that applies 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 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 Flat Dark Earth hardcoat anodizing.
