Reptilia 11.5" AR15 ARCA-S Black Handguard 100-401

The Reptilia 11.5" AR15 ARCA-S Handguard is a specialized free-float rail system designed for the AR15 platform, specifically optimized for short-to-medium barrel configurations. This model integrates a full-length ARCA-Swiss rail on the 6 o'clock position, allowing for seamless mounting to tripods and precision support systems. It utilizes Reptilia's patented turnbuckle mounting technology, which applies high-tension pressure against a standard 1.25-inch barrel nut to provide a rigid, anti-rotational lockup. Precision-machined from 6061-T6 aluminum extrusion, it features M-LOK slots at the 3 and 9 o'clock positions and a full-length Picatinny top rail, all finished in a durable MIL-STD Type III hardcoat anodizing.
