Atlas Custom Works Aluminum "Infinity Signature" Slide for Tokyo Marui 5.1 Hi-Capa GBB Airsoft Pistols, Gold

The stock Hi-Capa slide is steel and heavy. If you're building for competition or just want a lighter carry, swapping to an aluminum slide changes the balance. The Atlas Custom Works Infinity Signature Slide replaces the factory steel with CNC-machined aluminum, bringing the weight down to 150 grams while keeping the reciprocating mass needed for reliable gas blowback cycling.

The cut pattern. This follows the Infinity Signature profile — aggressive milling that removes material without compromising the rail interface or barrel bushing seating. The result is a slide that looks purpose-built rather than just polished. The gold finish is cosmetic; it does not indicate a specific FPS rating, port size, or performance band.

What you're actually getting. Just the slide. Your pistol's barrel, hop-up, magazine, and gas system stay as they are. If you want the matching lightweight blowback housing, that's sold separately.

Fit and compatibility. Designed for Tokyo Marui 5.1 Hi-Capa platforms and clones that follow the same dimensions. It is a drop-in replacement for the stock slide — no gunsmithing required. As with any GBB part, cycle it a few times with your chosen gas to verify smooth operation before heading to the field.

This is not a complete pistol. You need an existing Hi-Capa 5.1 frame and internals to use it. If you're starting from scratch, factor in the cost of the slide plus a donor gun or complete build.
