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

If you're building a Hi-Capa for competition, start with the slide. The Atlas Custom Works Infinity Signature Slide fits a Tokyo Marui 5.1 platform and changes how the gun cycles. At 150 grams, it's machined from CNC aluminum rather than cast, so you get lighter weight without losing the strength needed for repeated gas blowback cycles.

What the weight change does. A lighter slide cycles faster and uses less gas per shot. You get more rounds from a single magazine fill and a crisper blowback feel. On a GBB pistol, that's the difference between making a match and running dry halfway through a stage.

Design and fit. The Infinity Signature profile is based on the Infinity Strayer design, with machined cuts that reduce weight while keeping the slide rigid. It's a drop-in fit for Tokyo Marui Hi-Capa 5.1 series pistols and similar GBB platforms.

What to pair it with. This slide works with the ACW lightweight blowback housing, sold separately. You'll need a gas magazine and green gas or CO2—neither comes in the box. The purple finish is part of the aluminum.

Before you buy. This is a parts upgrade, not a complete pistol. If you don't already own a Hi-Capa 5.1 platform, you'll need to source one separately. For competitive builds, plan time for tuning the hop-up and testing velocity with the new slide installed.
