Tokyo Marui Hi-CAPA 5.1 Gas Blowback Airsoft Pistol in Black

If you've been around the airsoft scene for more than five minutes, chances are you've heard the name: Tokyo Marui Hi-CAPA 5.1. It's not just an airsoft pistol, it's a benchmark. Whether you're looking for a sidearm that just works out of the box or the perfect foundation for a tricked-out race build, the Hi-CAPA 5.1 is where the smart money goes. Trusted by competitive shooters, CQB regulars, and tech-savvy modders alike, this gas blowback legend has earned its reputation the hard way—on skirmish fields and speedsoft arenas around the world.

The design takes inspiration from custom .45ACP handguns, blending real-world practicality with airsoft precision. Its ABS slide keeps weight manageable while delivering fast, responsive cycling with every shot. Underneath, a robust metal frame ensures durability where it matters most, while the polymer grip maintains balance and comfort during extended use. It feels solid in hand without being a wrist killer.

At 222mm long and tipping the scales at 894g (magazine in), the Hi-CAPA has just the right heft to give you that authentic pistol feel without becoming cumbersome. The 112mm inner barrel and adjustable hop-up system give it top-tier accuracy for a sidearm. Tokyo Marui's renowned consistency shines here—BBs fly straight, true, and surprisingly far for a pistol, whether you're clearing rooms or covering teammates on the flanks.

Controls are ergonomic and accessible. The ambidextrous thumb safety is easy to reach whether you're right- or left-handed, and the trigger has a clean, predictable break that feels refined and responsive. The blowback action is crisp, with each shot delivering a nice little kick that adds to the realism without shaking your aim.

Need to mount a light or laser? No problem. A built-in 20mm Picatinny rail sits under the dust cover, ready for whatever tactical accessories you fancy. It’s ideal for CQB night games or if you simply want your setup to look the business. Don’t want extras? The pistol still looks sleek and clean on its own—like a proper race gun.

Out of the box, you’re getting a 31-round gas magazine that feeds smoothly and holds its gas like a champ. On 134a gas at room temp, you can easily get two to three mags' worth of BBs per fill. That’s solid efficiency, especially for a pistol with such a snappy slide. And yes, it works perfectly with extended magazines for those who want to push capacity further.

Where the Hi-CAPA 5.1 really shines, though, is its customisation potential. From CNC-machined slides and high-flow valves to short-stroke kits and competition hammers, the upgrade options are near-endless. Whether you're going for performance, aesthetics, or both, this airsoft gun offers a modular platform that grows with you as your skills and preferences evolve.

In short, the Tokyo Marui Hi-CAPA 5.1 isn’t just another GBB pistol—it’s the go-to. It’s earned its legendary status by doing everything right, and doing it with style. Whether you're new to airsoft or a veteran looking to refine your loadout, this is the kind of pistol that never feels like a compromise.
