Reptilia 13" AR15 ARCA-S Black Handguard 100-403

The Reptilia 13" AR15 ARCA-S Handguard is a specialized free-float rail system designed for the AR15 platform, specifically optimized for precision shooting and rapid tripod deployment. This "S" (Slim/Standard) variant of the ARCA series integrates a full-length ARCA-Swiss rail along the 6 o'clock position, allowing shooters to slide their rifle onto compatible tripod heads without the need for external adapters. It features Reptilia's patented turnbuckle mounting technology, which utilizes a reverse-threaded nut assembly to create high-tension pressure against a standard 1.25-inch barrel nut, ensuring a rock-solid, anti-rotational lockup that maintains zero for top-mounted lasers and optics. Precision-machined from 6061-T6 or 7075-T6 aluminum (depending on the run), the handguard includes M-LOK mounting slots at the 3 and 9 o'clock positions and a continuous Picatinny top rail, all protected by a durable MIL-STD Type III hardcoat anodized finish.
