Tokyo Marui Hi-Capa 5.1 Series Custom Slide Kit
Recoil Shock Reduction & Short Stroke for High-Speed Sniping!
No Sway While Rapid Shooting!
Enhanced Expansion with Upper and Lower Rails!
This Hi-Capa 5.1 High Speed Sniping System is compatible with the Tokyo Marui Gas Blowback Hi-Capa 5.1 series.
 
[POINT 1] Unmatched High-Speed Shots
The slide is divided into front and rear sections, and with dedicated internal parts, it achieves both lightweight and short stroke. This design increases blowback speed while significantly reducing recoil shock, allowing you to shoot rapidly without swaying and keep hitting the same point consistently.
 
[POINT 2] Functional Modular Structure of Slide and Front Block
The front part of the slide (front block) is made of aluminum alloy, functioning as a counterweight to minimize sway during rapid firing. The cut-out position for the slide stop is adjusted to ensure it functions properly, even with a short stroke.
 
[POINT 3] Equipped with Accuracy Ring and Expandable Rails
An internal accuracy O-ring helps to securely hold the outer barrel in position. The underframe comes standard with a Picatinny rail, and additional rail panels can be installed on the front block.
 
[POINT 4] Independent Split Structure Enhances the Effectiveness of Expansion Parts
Since the front block is independent of the slide, adding optical devices and other attachments does not affect slide operation. Attach a foregrip or dot sight, and your handgun will deliver firepower that is beyond expectations!
 
[POINT 5] Comprehensive Set with 11 Dedicated Parts and Screws
The kit includes specially designed parts not only for the slide and front block but also for the recoil spring, piston, and more. The extensive set is sure to satisfy heavy Hi-Capa users, offering a rewarding customization experience.
