Product information

The KWA Originals EVE-4 is a compact M4-pattern AEG designed around KWA’s adjustable-power drivetrain. A UK retailer lists approximately 21–26 inches (about 533–660 mm) overall length and a UK-facing configuration around 330 FPS on 0.20 g.

The model uses M-LOK furniture, Deans wiring and KWA’s variable-performance system. The record keeps the UK retail configuration separate from higher factory adjustment ranges.

Enter FPS and BB weight to calculate muzzle energy.

Published figures are a reference, not your replica’s chrono result. Equivalent speeds assume the same energy; changing BB weight can change measured energy. Check your own readings and your field’s limits.

Magazine notes

Uses standard M4/STANAG AEG magazines; KWA supplies a 120-round magazine.

A shared pattern or interface helps narrow your search; it does not guarantee fit across every brand or revision. Follow model-specific notes.
