Compatibility & Upgrades
The EVE-4 uses standard P90 AEG magazines; King Arms branded magazines are recommended for optimal feeding reliability. The V6 gearbox is a widely-supported platform—experienced technicians can upgrade the motor, spring, and internal components to boost fps or improve trigger response without major modifications.
The 20mm RIS rail system accepts industry-standard optics, laser modules, and foregrips, letting you tailor the rifle to your role and skirmish environment. Hand-accessible hop-up adjustment means field tuning takes seconds.
UK Legal & Site Notes
The KWA EVE-4 is a two-tone airsoft rifle (available in black or pre two-tone pink) and complies with UK airsoft site safety limits. Always check your local site’s fps and magazine capacity rules before attending. The 100-round magazine is typical for CQB environments; some outdoor sites may impose stricter capacity limits. Never remove the two-tone finish on the live version.
