What is the CM4 C4-10?
The CM4 C4-10 brings licensed Centurion Arms trademarks and engravings to KWA’s AEG 3 recoil system. The Kinetic Feedback System simulates recoil, and with KWA’s switchable 30/120-round ERG, AEG 2.5 and AEG 3 magazines the cut-off stops the rifle electrically when the last round is fired. If you want to skip the cut-off, any standard AEG magazine fits.
PTS furniture comes standard: the Enhanced Polymer Grip Compact, Enhanced Back-Up Iron Sights with elevation and windage adjustment and dual apertures, the Enhanced Polymer Magazine and the Enhanced Polymer Stock with storage compartments. A quick-change spring system lets you tune FPS to your needs.

How the CM4 C4-10 works
The Kinetic Feedback System
KWA’s electronic recoil system replicates the movement of a reciprocating bolt, so you feel a kick with every shot while keeping the reliability of an AEG.
In semi-auto every shot kicks. In full auto it adds a rhythm you can feel at 19+ rounds per second.
How the cut-off works
When the magazine runs empty, the cut-off gearbox stops the rifle from firing. Insert a fresh magazine, disengage the mock bolt catch and keep going.
It builds reload muscle memory for training and games.
Which magazines to use
Standard M4 AEG magazines work in this rifle. To use the cut-off, run KWA’s designated cut-off magazines: the K120C or MS120C.
The included PTS Enhanced Polymer Magazine toggles between 30 and 120 rounds with the flip of a switch.
Choosing a battery
The battery and charger are not included. This rifle takes NiMH or Li-Po/Li-Fe batteries with a Tamiya connector (2020 version), rear-wired. It can handle 11.1v Li-Po batteries.
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.
