Tokyo Marui Hi-CAPA 5.1 (Government Model) GBB Pistol

Tokyo Marui Hi-Capa 5.1 Government Model GBB Pistol

The Undisputed Legend. The Ultimate Custom Canvas.

Walk into any airsoft site in the world—whether it's a fast-paced indoor CQB arena or a massive outdoor woodland field—and you are guaranteed to see the Tokyo Marui Hi-Capa 5.1.

This isn't just a sidearm; it is the single most successful, relied-upon, and customizable gas blowback pistol platform in airsoft history. Engineered by the masters at Tokyo Marui, the Hi-Capa 5.1 is world-renowned for its hair-trigger speed, relentless gas efficiency, and target-dot accuracy. Whether you want a flawless out-of-the-box skirmish tool or the ultimate foundation for a fully upgraded, brightly colored custom race gun, the Hi-Capa 5.1 is the gold standard.

Why the Hi-Capa 5.1 Rules the Pistol World

1. The Snappiest Gas Performance in the Game

Tokyo Marui pioneered high-density polymer slides for a reason. Because the slide is lightweight, it requires less gas pressure to cycle backward. This yields a blistering cyclic rate, a crisp trigger reset, and unparalleled cold-weather performance. You can comfortably dump entire magazines in rapid succession without the pistol suffering from standard gas cooldown freeze-ups.

2. Massive Aftermarket Part Eco-system

The TM Hi-Capa is the Honda Civic of the airsoft world. Because it is the industry-standard design, there are thousands of aftermarket parts available from brands like CowCow, AM, Laylax, and Guarder. If you want to change the slide to lightweight aluminium, drop in a high-speed short stroke kit, or swap the entire frame to a custom colour, the sky is the limit.

3. High-Capacity 31-Round Magazine

Based loosely on double-stack 2011 race guns, the Hi-Capa features a wide, solid metal magazine that holds a substantial 31 rounds. The extra width means a massive internal gas reservoir, giving you more than enough juice to clear a whole room on a single fill of green gas.

4. Fully Adjustable Target Sights

Up top, the pistol features a fully adjustable rear target sight. Using a flathead screwdriver, you can finely adjust your windage and elevation to dial the point of aim directly into your preferred BB weight. Pair that with TM’s magical rotary hop-up system, and this pistol will easily out-range many standard rifles.

BZ Tech Team Advice: The Hi-Capa Care Guide

Keep it Cyclic and Clean

Because the slide is high-density ABS polymer, running excessively high-pressure gas can eventually stress the slide catch notch over thousands of rounds.

• The Perfect Gas Setup: In warm weather (above 15°C), stick strictly to low-pressure Abbey 144a gas to keep your slide completely stress-free while maintaining a perfect cycle. In colder winter months, step up to standard Green Gas (like Nuprol 2.0 or Abbey Ultra) to keep the blowback snappy.
• Want to shoot faster? Dropping a set of cowcow short-stroke buffers onto your recoil guide rod is the cheapest and fastest way to cut slide travel time in half, giving you insane trigger split times for CQB room clearing!
