Compatibility: Tokyo Marui 5.1/4.3
The AIP Enhanced Recoil Spring essentially short strokes the pistol, disabling the slide from travelling all the way back. This keeps the slide from locking while also increasing fire rate since the travel distance is shorter.
- Decreases travel distance of slide
- Increases fire rate
