HILLSBOROUGH, NC – September 2026 – Reptilia Corp introduces the Arca-S Handguard, a purpose-built rifle handguard designed around a machined-in Arca-Swiss interface that provides direct-to-tripod capability without sacrificing the modularity of a modern M-LOK handguard.
Designed for shooters who rely on a tripod for stability, positional shooting, observation, or rapid rifle deployment, the Arca-S Handguard integrates a 2.8” Arca-S section at the rear of the handguard, where the rail meets the upper receiver. This location provides a rigid, repeatable mounting interface while keeping the remainder of the handguard clean and fully configurable.
“The goal was to integrate the Arca interface into the handguard rather than bolt another component onto the rifle,” said Reptilia. “The result is a cleaner, more capable system that gives the shooter direct access to a tripod while maintaining the M-LOK functionality they expect.”
At the center of the design is Reptilia’s patented turnbuckle mounting system, which provides a secure and repeatable attachment across standard AR15 upper receivers without adding unnecessary bulk. The handguard maintains full M-LOK compatibility, allowing shooters to configure their rifle with bipods, lights, and other accessories alongside the integrated Arca interface.
The Arca-S interface draws from the Arca-Swiss standard originally developed for precision photography and now widely adopted by shooters seeking fast attachment, smooth fore-and-aft adjustment, and a stable connection to a tripod. By machining the interface directly into the handguard, Reptilia eliminates the need for an additional Arca rail or adapter.
