Gunsmith Bros Aluminium ST Style Rear Sight For Marui TM Hi-Capa 5.1 GBBP Series

This Gunsmith Bros rear sight is a direct-fit upgrade for the Tokyo Marui Hi-Capa 5.1 GBB pistol series, giving you a precise sight picture for range and competition use. Its ST-style profile matches the look of custom race guns, while the CNC-machined aluminium construction keeps the part light and stable on the slide.

Because it is designed specifically for the Hi-Capa 5.1 platform, installation is straightforward and the fit is consistent with the pistol's original mounting points. The aluminium body resists wear from repeated cycling, making it a practical choice for shooters who want a durable, low-profile rear sight without adding bulk.
