Dr. Black Type W MOS Aluminum Slide for Tokyo Marui Hi-Capa 5.1 GBB Pistols

The Dr. Black Type W MOS Aluminum Slide is a lightweight, optics-ready upgrade designed specifically for Tokyo Marui Hi-Capa 5.1 gas blowback pistols. CNC machined from 6061-T6 aluminum and weighing just 78 grams, the Type W combines the durability of an aluminum slide with a lightweight design intended to keep the pistol cycling quickly and efficiently.

The Type W features an aggressive modern profile with strategically placed slide cutouts that reduce reciprocating mass while giving the pistol a distinctive competition-inspired appearance. Partially knurled gripping surfaces provide additional traction when manually cycling the slide, making manipulation easier during loading, maintenance, and gameplay.

Unlike a conventional Hi-Capa slide, this MOS version incorporates an optics-ready mounting area directly into the slide design while retaining provisions for iron sights. This makes the Type W an excellent foundation for players building an optics-equipped Hi-Capa without relying on a large frame-mounted optic system. Pair it with the appropriate Dr. Black Type W / Type Y red dot adapter plate to configure the slide for a compatible micro red dot sight.

Available in Dr. Black's full range of anodized colors, the Type W is equally at home on a lightweight competition build, speedsoft pistol, or fully customized Hi-Capa. At only 78 grams, it provides a substantial aluminum construction while keeping reciprocating weight low for responsive blowback operation.
