Atlas Custom Works CNC Aluminum Matrix Kit for Marui Hi-Capa GBB Airsoft Pistols, Red/Gold

The Hi-Capa is one of the most customizable GBB pistols in airsoft. Players chase better ergonomics, different looks, and the satisfaction of building something unique. The Atlas Custom Works Matrix Kit is a complete external upgrade that changes how the pistol looks and feels without touching the internals.

What's in the kit. You get a CNC aluminum slide set, recoil spring guide, and hammer housing. The aluminum is machined rather than cast, which means tighter tolerances and a more substantial feel in hand. At roughly 15.5 oz, this adds noticeable weight compared to the factory polymer slide, shifting the balance forward for a steadier hold during rapid fire.

The Red/Gold anodized finish is purely cosmetic. It does not indicate a performance rating or FPS band. If you want a pistol that stands out on the range, this does that.

What this does not do. This is an external upgrade only. It does not change velocity, rate of fire, or reliability. The gun will still run on the same gas and BBs as before. If you are looking for performance gains, look at inner barrel, hop-up, or valve upgrades instead.

Compatibility. The kit fits Tokyo Marui Hi-Capa series and compatible clones. Standard Hi-Capa magazines work without modification. Installation requires basic hand tools and familiarity with GBB disassembly.

Includes the slide set, recoil spring guide, and hammer housing. Gas magazines and charging handles are sold separately.
