Marui HI-CAPA 5.1 150% Spring | Ra-Tech

Marui HI-CAPA 5.1 150% Spring | Ra-Tech – for your replica

This recoil spring for the HI-CAPA 5.1 gives your pistol increased recoil and ensures faster slide cycling. As a standard upgrade for GBB pistols, a stronger spring helps to consistently return the slide, especially when using green gas or CO₂. Replacing the recoil spring is a common upgrade when you have modified other internal parts or when the original spring is worn out.

Technical specifications

The Ra-Tech 150% spring has a higher spring force than standard springs. The material is spring steel with a grey finish. The spring is specifically designed for the dimensions of HI-CAPA frames and slides. With 50% higher tension, this spring provides more resistance when pushing the slide back.

Compatibility and application

This spring fits Tokyo Marui HI-CAPA 5.1 models and compatible variants. Installation requires disassembly of the slide, during which you remove the guide rod and buffer. For technicians with basic experience in GBB maintenance, this is a straightforward upgrade. The spring performs best in combination with reinforced internals and when using more powerful gases.
