What is the KO: EVE-9 FDE?
The EVE-9 is the longer of the KO Eves, made to rival KWA’s Ronin T10 without the kick of the recoil system, and a nod back to KWA’s original Ronin 10 SBR. Its high-strength polymer receiver set and M-LOK handguard keep it light (5.6 lb) and well balanced. This version is finished in flat dark earth.
The side charging handle makes hop-up adjustment convenient, the integrated pistol grip is shaped for comfortable handling, and KO’s slim line vertical grip and a PTS stock give it a sleek look. Inside is the same adjustable-FPS (VPS) gearbox used in the Ronin TK.45c, Ronin T6, QRF Mod series and Ronin 47, ready for an ETU when you want one.
Who it is for: players who want a longer, light KO rifle for mid-range games, with FPS they can tune for each field.

How the KO: EVE-9 FDE works
Adjusting FPS with VPS
The Variable Performance System changes power at the gearbox. On the EVE-9 you adjust it with the included VPS tool, within 330–380 FPS.
Fields set velocity limits, often lower indoors than outdoors. Set the rifle for the field you are playing and confirm it at chrono.
Which magazines to use
The EVE-9 takes M4/AR15-style AEG magazines. It comes with one KWA MS120 120-round magazine, and MS120 3-packs in Ice, Mint and Midnight are sold separately.
Ready for an ETU upgrade
The gearbox is drop-in ready for popular electronic trigger units, so an upgrade needs no gearbox modification.
If you would rather start with an ETU already installed, the Ronin T6 and T10 ship with the KWA ETU.
Choosing a battery
The battery and charger are not included. This rifle takes 11.1V Li-Po batteries with a T-plug (Deans) connector.
Match the connector, check that the battery fits the stock or battery space, and charge it only with a charger made for that battery type. Ask KWA if you are not sure which size fits.
Hop-up, explained
Hop-up puts backspin on the BB so it lifts and flies flatter and farther. Too little and BBs drop early. Too much and they climb.
- Start with the hop-up at its lowest setting.
- Fire a few shots at a target at your usual distance.
- Add a little hop at a time until BBs fly flat before they drop.
- Back it off if BBs start to rise. Re-check whenever you change BB weight.
Compare the KO family
