Atlas Custom Works LimCat Protector 5.1 CNC Aluminum Slide for Tokyo Marui Hi-Capa 5.1 GBB Pistols, Red

The Hi-Capa platform is all about customization. You start with a reliable GBB pistol and build it around how you shoot — competition, training, or just the way it looks and feels in hand. The LimCat Protector slide is one of those upgrades that changes both.

CNC aluminum, not cast. This is machined from a solid block of aluminum, not die-cast. The Red anodized coating is the finish.

The LimCat pattern. The circuitry-style lines cut into the slide give you a textured surface when racking, which helps when your hands are sweaty or you're wearing gloves.

Fit and compatibility. This slide is made for Tokyo Marui Hi-Capa 5.1 GBB pistols and platforms built to that spec. If you're running a clone or a different frame, check the fit before you buy. Hi-Capa parts are generally interchangeable within the ecosystem, but not everything labeled "Hi-Capa" follows the same dimensions.

What you're getting. Just the slide. No barrel, no inner parts, no gun. You're upgrading an existing pistol, not building one from scratch. Installation requires disassembling your GBB and fitting the slide to your frame — it's not a beginner task. If you've never worked on a Hi-Capa before, have someone who has walk you through it.

Includes the slide only. Assembly hardware and installation tools are not included.
