The Tokyo Marui Hi-Capa 5.1 Stainless is a gas blowback replica developed for users seeking reliability, consistent performance and a refined appearance. The stainless look is achieved through steel-colored finishes on the slide, chassis and external details, while the entire structure is made of extremely durable high-grade polymer, ensuring reduced weight, excellent balance and long-term durability.

Designed around a modern custom government-style platform, this Hi-Capa features a double-stack magazine that solves the traditional capacity limits of single-column pistols. The variable hop-up system allows fine tuning of BB trajectory, while the strong blowback action provides realistic recoil and slide movement during semi-automatic firing.

The square heavy-profile slide includes an anti-reflection groove to improve sight alignment, combined with a fully adjustable rear sight for both windage and elevation. An ambidextrous thumb safety allows practical handling for both right- and left-handed users. The integrated Picatinny under-rail enables the mounting of tactical accessories such as flashlights or lasers, making this replica suitable for dynamic softair scenarios.

End-user advantages

High magazine capacity for extended gameplay, realistic shooting feedback, durable polymer construction and compatibility with standard Picatinny accessories — an ideal choice for demanding softgunners.
