Description.

The Tokyo Marui Hi-CAPA 5.1 Gas Blowback Airsoft Pistol in black isn’t just a reliable sidearm—it’s an institution. Ask any competitive shooter, speedsofter, or experienced skirmisher, and chances are their first or favourite pistol is a Hi-CAPA. Why? Because it delivers straight out of the box. Consistent gas performance, exceptional accuracy, smooth cycling, and massive upgrade potential—this GBB ticks every box.

This Hi-CAPA 5.1 “Government Model” is inspired by custom pistols used by elite forces, designed to reflect the latest in tactical firearm design. With a full-length build of 222mm and a comfortable 894g weight with magazine inserted, it handles beautifully. The square-profile ABS slide and metal internals create a snappy recoil cycle without dragging down your draw or slowing your follow-up shots. It may be ABS, but Tokyo Marui’s proprietary blend is robust, fast-cycling, and cold-weather friendly.

It’s all about adaptability. This model features a functional Picatinny under rail that allows you to mount lights or lasers, perfect for CQB loadouts. If you prefer a cleaner look for sports shooting, the rail can be left bare. The slide itself includes a subtle anti-reflection groove—a finely cut series of lines running along the top of the slide, reducing glare when sighting. Combined with a fully adjustable rear sight (vertical and horizontal), this pistol is more than capable of surgical precision on the field.

The grip system, constructed from a combination of polymer and a metal chassis, makes room for a generous double-stack 31-round magazine. This setup solves the traditional low-capacity drawback of government-style pistols. Marui’s gas efficiency here is exceptional—you can easily get 2–3 full mags from a single fill on 134a or green gas depending on ambient temperature. The controls are player-friendly too, with ambidextrous thumb safeties and an easy-to-rack square slide that offers excellent grip even in gloves or wet conditions.

Performance-wise, you’re looking at an average velocity of around 280 FPS using 0.20g BBs. For best results, we recommend 0.25g for improved accuracy and more stable flight paths. The variable hop-up, accessed by removing the slide, lets you fine-tune trajectory to match your shooting style or field type. Whether you're pushing corners in tight CQB or taking longer shots outdoors, the Hi-CAPA adapts and performs without fuss.

And let’s not forget: the Tokyo Marui Hi-CAPA platform has the widest aftermarket support of any airsoft pistol. Literally every component—frame, slide, barrel, hop unit, trigger, nozzle, hammer—can be replaced, upgraded, or tweaked. That’s why this pistol isn’t just a skirmish staple—it’s the base for most custom builds and race guns on the competition circuit. Straight from the box, it's one of the most skirmish-capable pistols available. Fully upgraded? It’s a monster.

Other Great Features are,

Chrome-plated outer barrel and hammer for visual contrast
Polymer grip over metal frame for balance and durability
Fast, consistent cycling with high gas efficiency
