The CTM NAVIARA Hi-Capa 5.1 series takes design cues from maritime navigation and yacht aesthetics. The name combines "NAVI," representing direction and control, with "ARA," inspired by aerial fluidity. Moving away from standard Hi-Capa frameworks, the model features a split-slide design intended to balance a streamlined appearance with functional precision.

Development focused on long-term durability and operational reliability. To address the mechanical demands of the split-slide system, prototype samples underwent stress testing involving approximately 50,000 rounds prior to production. The final build utilizes 6061 CNC aluminum and a fixed barrel design, supported by a steel guide rod and an enhanced nozzle system to maintain cycling consistency.

The NAVIARA is delivered as a comprehensive kit, including a TDC hop-up wheel, a short-stroke kit, and an ambidextrous charging handle. It features a half-ghost ring sight for rapid target acquisition and an integrated optic plate on the outer barrel for co-witnessing. Compatible with Tokyo Marui 5.1 and 4.3 specifications, the package aims to provide a complete out-of-the-box solution for players seeking a technical upgrade to their current platforms.
